Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many professional writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my paper for plagiarism and then to hire a professional writer to fix your task quickly if you’re busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue working on their assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before. Unlike copying and pasting each passage individually into Google, simply upload the whole file into our plagiarism checker free for students, and you don’t have to do anything else. All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.

1. Unicheck

Our expert review:

Reasons to buy

Reasons to avoid.

Unicheck provides a high-quality service by combining high-end technology with smart design, and it clearly works – more than 1,000 academic institutions worldwide use this app.

This tool has access to more than 91 billion pages and library files, so you can be sure that it’s checking every source available for plagiarized material. And don’t worry about being overwhelmed with data once the app has searched the web, either: results appear in a straightforward interface that displays sources and color-codes copy, and each piece has a plagiarism score that’s adjusted as you edit the article.

Unicheck’s 99.9% system uptime means you’ll be able to check for plagiarism when you need it, and its authorized, encrypted accounts deliver high-level security for users.

The versatility and power continue elsewhere. A personal dashboard is perfect for managing loads of sources or articles, and Unicheck integrates with Office 365, Google Docs, and Chrome, so you can check for plagiarism without ever leaving those apps. It’s got an accessible API, too, so the tool integrates with other services.

Unicheck doesn’t have to be expensive, either. Its Personal package costs as little as $5 and scales up depending on how many pages you’d like to check, and there are more extensive packages for educational establishments and businesses. No matter which one you choose, though, it’s clear that Unicheck remains one of the best plagiarism checkers on the market.

Scribbr provides a plagiarism checker that is part of a wider suite of tools that include an academic proofreading module and an APA reference generator. Unsurprisingly, the products on offer here will appeal to students and academics, and the site helps craft dissertations, essays, and thesis documents.

The plagiarism checker does a stellar job. Scribbr partners with Turnitin, which can detect everything from precise word and phrase matches to language where synonyms have been to used, and Scribbr checks writing against a database that covers 91 billion web pages and 69 million publications. Impressively, you can upload old assignments or referenced works to compare, too – perfect if you want to check your writing against something that won’t be in Scribbr’s database.

Beyond plagiarism, Scribbr offers expert editors who can edit essays, thesis documents, funding proposals, and literary reviews – it’s ideal for making sure that your academic work is top-notch, no matter the subject. Scribbr also provides a generator and checker for APA citations so you can be sure that no-one will question your sources.

Scibbr’s plagiarism checking service ranges in price from around $20 / £14 / AU$27  to $40 / £32 / AU$63, depending on the length of the document, and you’ll get your checked document within ten minutes.

The lack of dashboard and security features, when compared to other services, means that Scribbr isn’t suitable for large enterprises. But if you’re a student or academic, it’s well-designed and potentially invaluable.

3. Grammarly

Grammarly is one of the world’s most popular writing assistants, and no wonder: it does a fantastic job of checking written work for linguistic accuracy alongside its readability and tone. It’s also available as an app, as a plug-in for most word processing tools and as a browser extension.

It works in email clients , on social networks, and even in Slack and Discord too – so you’ll always be able to rely on this tool.

Grammarly has a great plagiarism checker, too. It uses the academic papers in ProQuest’s database and more than 16 billion web page sources to check for plagiarized text, and if the app detects copied language or phrases then you’ll get an alert in your document.

Grammarly’s plagiarism checker is free to use, but we don’t recommend this option – it will tell you if you’ve plagiarized, but it won’t show you where.

Instead, we recommend signing up to Grammarly’s paid tiers – you get its grammar, spelling, and punctuation tools alongside its clarity, engagement, tone, and plagiarism detection. Grammarly is one of the best linguistic tools on the web.

Grammarly’s prices start at around $11 / £10 / AU$16 per month.

4. PlagScan

PlagScan is a robust plagiarism deterrent focused on the academic circle. While used by many other fields as well, the features that make PlagScan stand apart among other plagiarism tools seem geared in this direction.

Pricing is pretty reasonable, with plans per word for individuals and some business plans as well. Prices can vary from $6 - $50 or more on average. On the higher level plans, there are advanced features including API abilities, support and more. There is also the ability to create more detailed reporting and integrate with tools you are already using.

Compared to other tools, PlagScan is pretty good about picking up possibilities, albeit sometimes too good. There are the occasional mistake, as in it notifies of a plagiarized item that is not actually there, however all around this tool is fairly accurate.

PlagScan itself even will say that the only true way to see if something is plagiarized is to utilize human support, confirming what PlagScan finds. But, without this tool, you would take much longer to find these similarities!

Lastly, there are easy color-coding highlights that help show what kind of infraction is found in offending pieces of writing.

Read our full PlagScan review .

5. Plagramme

Plagramme has a range of features that goes beyond what you’ll find with many other anti-plagiarism tools. It doesn’t just check billions of sources – it highlights your article with plagiarism risks, potentially paraphrased sections, poor citations, and textual similarities. Combine this with a straightforward scoring system, and you’ll be able to quickly see how much of any article is at risk.

This system is multilingual, so it can detect issues in different languages, and Plagramme also offers an authenticity service where its own editors check and fix documents manually. This does cost more, but it’s ideal if you have an important document that needs perfection. And, at the other end of the scale, there’s a free plagiarism checker – although this performs a quick check without the in-depth reporting or database access of the full product.

Once you’ve signed up for an account then you’ll be able to see Plagramme’s full range of services. It’ll cost a few dollars to skip the queue and a few more to get an in-depth report, and you can buy credits that work on any of Plagramme’s services.

This credit-based system and the emphasis on individual documents mean that Plagramme may not suit large organizations, but it’s well-suited to individuals and small businesses. 

Quetext has plagiarism detection algorithms that use a system called DeepSearch, which relies on word placement, deep learning, and contextual analysis to deliver smarter and more sensible results when you scan a document.

This tool can check for plagiarism in academic documents, news articles, blog posts, and webpages, so it’s versatile. It’s easy to use too: potentially plagiarized words or phrases are highlighted using a color-coded system with bolder shades for more significant issues. Side-by-side displays mean you can see exactly where the plagiarized text originated. And, at the end of the process, content gets a score so you can see how it’s performed.

Quetext also prizes itself on its straightforward pricing. If you pay for the basic package that allows you to check 100,000 words. The Plus package doubles the cost and increases the word allowance to 250,000, and there’s an Organization option that’s ideal for companies. Impressively, every product includes every feature – the good stuff is never held back for those who are willing to pay more.

Plagiarism checker FAQs

What is plagiarism.

Simply put, plagiarism is cheating. it refers to the act of copying one’s content and passing it off as your own. Grabbing someone’s photo and using it without permission and/or proper credits can be considered an act of plagiarism. Taking some text from a source and using it on your website without proper citation is also an act of plagiarism. 

In college, getting caught plagiarizing can lead to expulsion and can ultimately end any plans you have for your future. Stealing content for your own blog is not considered a form of flattery either, nor is it legal. Copying content for your own website can get you reported and your website taken down. 

What are the common types of plagiarism?

There are a couple of ways to commit plagiarism, but here are the five most common types:

1. Verbatim plagiarism - This is a common crime wherein a text or content is copied exactly as it is written without any form of credit or citation. 

2. Mosaic plagiarism - This type of plagiarism involves copying content from different websites or sources and combining them without any form of credit or citation. 

3. Global plagiarism - This means deliberately claiming someone else’s entire work as your own. 

4. Self plagiarism - This is when you resubmit your own work when you’ve already used it. It’s also known as auto plagiarism.

5. Accidental plagiarism - This occurs when you unintentionally commit plagiarism by paraphrasing a content and failing to cite or add credits. 

As content is a vital ingredient in SEO ranking which is always a neck to neck competition, websites are usually trying to come up with more content than they likely would have expected to be needing. A team of writers usually solve the problem, but it’s also where a new problem arises - monitoring the content.

Whether it’s an intentional copying of content or a missed citation, quote or credit, plagiarism isn’t as easy to detect if you’re dealing with tons of articles to check. The good news is that there are resources available - plagiarism checkers - that you can utilize to make it an easier task.

How to choose the best plagiarism checkers for you?

When choosing the best plagiarism checker for yourself, you'll want to start with assessing whether you want a standalone plagiarism checker or something with more features to improve writing. 

You'll want to consider the tool's user interface and learning curve. The simpler it is to operate, the more efficient you can be with your checking. 

If you're working alone, you may do well with a certain type of plagiarism checker, but the same tool may not be suitable for larger organizations. 

You'll also want to take the plagiarism tool's pricing into consideration, check how many users it can support, and analyze how well it integrates with third-party apps. 

How we test the best plagiarism checkers

To test the best plagiarism checkers, we first evaluated whether the tools are standalone plagiarism checkers or if they offer a suite of language improvement tools. 

We analyzed how large their content database is, whether there's citation checking, and what third-party apps they integrate with.

We assessed the tools' user interface and learning curve, and the kind of algorithm they were using to effectively spot plagiarism. We also considered their pricing plans, the number of users supported on each plan, and what type of client they'd be ideal for, among other things.

Best Plagiarism Software for Thesis: 8 Top Options (2024)

Discover what to expect from the best plagiarism software for thesis.

Several years ago, I completed a postgraduate degree. My tutor underlined the importance of consulting a range of primary and secondary sources with correct citations. I spent almost as much time checking my citations and references as I did writing the first draft! Thankfully, students can save significant time on this part of thesis writing using plagiarism software.

Turnitin is the most popular plagiarism software in academia, but not every student has access. It’s not freely available online either, but a workaround exists. I’ve spent dozens of hours testing and using popular plagiarism tools. I use them to check blog posts, articles, books, essays and technical papers. In this article, I profile the best plagiarism tools for your thesis.

4. quillbot, 5. prowritingaid, 6. copyscape, 7. paperrater, 8. correctenglish (ce), what is the best plagiarism software for a thesis, why you can trust us, our testing criteria, what is the best alternative to turnitin.

Use for: accessing Turnitin Pricing: $19.95 to check 7,500 words

Turnitin is the number one plagiarism tool used by academic assessors. If you have access to this tool, stick with it. Unfortunately, TurnItIn isn’t widely available outside of academia. Enter Scribbr. It’s powered by Turnitin and scans web pages and over eight million publications. That sets it apart from other tools here. Our reviewer found Scribbr easy to use, insightful and relatively accurate. It also includes a citation generator. It’s ideal for checking a thesis for plagiarism.

QueText is aimed at teachers, academics and general writers. Like Scribbr, it checks for plagiarism against web content and online textbooks.

QueText’s key selling point for thesis writers is its DeepSearch technology, which checks against gated content. It took us about two minutes to review a 754-word essay extract, which is somewhat slower than other tools. Interestingly, this DeepSearch feature found references to our essay on Twitter and web.archive.org. Some of the other tools featured here didn’t check these sources.

QueText also supports multiple languages, including Spanish, French, Polish, German, and Dutch. It also includes a citation assistant. Thesis writers can check up to 500 words for free once they sign up.

• Free (albeit limited) version available
• Checks against some gated academic content
• Fair pricing
• Supports multiple languages
• Monthly payments only
• Grammar checks lag behind competitors
• Somewhat slower than other tools

Use for: general plagiarism and grammar checks Pricing: $30 per month

Grammarly Premium excels as plagiarism software. It’s ideal for most students and thesis writers, with some caveats.

Grammarly’s strength is it works across platforms and devices, including Windows and Mac, and browsers like Chrome, Firefox and Safari. I regularly use the Gmail, Chrome extension and Google Docs plugin to run plagiarism checks on articles and essays.

However, thesis writers must use Grammarly Premium, as the free version doesn’t include plagiarism checks. It took us about 20 seconds to check 754 words. You’ll need to paste or upload each chapter rather than the entirety of your thesis.

Grammarly only checks against articles freely available online. So, don’t expect it to check your work against gated academic papers. It also lacks a dedicated citation manager. The grammar checker excels, though.

To learn more, read our Grammarly review.

• Quick and easy to use
• Best-in-glass grammar and plagiarism checker
• Works on most popular devices
• Pricey for students
• Plagiarism check included with Grammarly Premium only
• No citation manager

We tested dozens of grammar checkers, and Grammarly is the best tool on the market today. It'll help you write and edit your work much faster. Grammarly provides a powerful AI writing assistant and plagiarism checker.

Use for: Plagiarism checks, building a bibliography, managing citations Pricing: $19.95 per month, $7.45 per page

Quillbot is an excellent all-around academic writing tool.

Creating a good reference and bibliography for a thesis is key if you want to avoid accusations of plagiarism. We liked Quillbot’s citation generator as it saved us time creating these for a paper.

This generator formats any link, document or reference based on a student’s preferred style and generates the correct citation. Quillbot customers also get access to other premium tools for rewriting and summarizing. Remember to cite your sources, though!

The plagiarism checker works similarly to Grammarly, except it’s billed per page. A page is approximately 300 words, and 25 pages cost $7.45, with discounts available. It’d cost $25–50 to check a thesis of average length (say 35,000 words). It took us about two minutes to check 754 words. The accuracy was on par with Grammarly but not as deep as QueText.

To learn more, read our Quillbot review.

Quillbot is a best-in-class essay checker and paraphrasing tool. It's a great choice for essayists, academics and content writers.

• A plethora of valuable tools beyond plagiarism reports
• Fast and easy to use
• Excellent citation generation
• Grammar reports lag behind Grammarly
• Plagiarism checks are billed per page

Use for: Basic plagiarism and grammar checks Pricing: $70 per year; plagiarism reports start at $10 for ten checks.

ProWritingAid is an excellent alternative to Grammarly for fixing grammar issues in a thesis. However, it’s less useful as an academic plagiarism checker. Firstly, it’s slower to use than the tools above. Secondly, in our tests, ProWritingAid missed some instances of plagiarism that other devices caught. Billing for plagiarism checks is also somewhat confusing.

To learn more, read our ProWritingAid review.

ProWritingAid is a powerful, accurate grammar checker and style editor. It's suitable for non-fiction and fiction writers and doesn't require a monthly subscription. Save 20% per month or year.

• Excellent grammar reports
• Supports long-form documents
• Volume of reports may overwhelm new users
• Less suitable for academic plagiarism checks

Use for: plagiarism checks for online content, on a per-page basis Pricing: 3 cents per search, up to 200 words

Copyscape isn’t a purpose-built plagiarism tool for a thesis writer, but we’d be remiss to exclude it. It scans text for instances of plagiarism, accidental or otherwise. It doesn’t require a monthly subscription. A $100 in credits is more than enough to check any thesis, as these last a year.

Like other tools, it only scans against content freely available online. It’s great for sourcing missing citations and cheaper than Grammarly. Don’t expect it to dig behind academic paywalls, though.

To learn more, read our Copyscape review.

• Excellent plagiarism report
• Credits last a year
• No grammar checker
• Small learning curve
• Less suitable for academia

Use for: checking essays and college submissions on a budget Pricing: $7.95 per month

PaperRater helps students write better essays and articles. It was founded in 2009 and is owned by Barnes and Noble Education. PaperRater relies on artificial intelligence to check a thesis for spelling mistakes and plagiarism issues.

Our reviewer tried it. He reported that Paperrater missed mistakes in his essays. It also missed other plagiarism issues Grammarly caught. He also missed general proofreading reports from other apps. Still, it’s relatively affordable, and you can check some of your thesis for free (several hundred words).

To learn more, read our Paperrater vs Grammarly comparison.

• Free plagiarism checker
• Questionable accuracy

Use for: Checking essays, applying style guides Pricing: $24 per month

Correct English is a lesser-known plagiarism and grammar tool for the academic market. It’s aimed at students writing in English as a second language via support for nine languages.

We uploaded extracts from Google Docs and Microsoft Word essays. The user interface is like software from the early 2000s, prompting us to save repeatedly.

We tested our paper using the tool’s Original Detector. Despite several attempts, we couldn’t get the plagiarism report to work correctly and had issues with document control.

At least the grammar checker is good. Correct English supports various writing style guides, including APA and MLA. We’ve yet to find another comparable tool with a similar feature.

• Supports nine languages
• Supports academic style guides
• Supports sharing and collaboration
• Insightful writing stats
• Document control issues
• Plagiarism report buggy
• Lacks plugins and apps for browsers
• Clunky user-interface

Use Turnitin if you have access to it. If not, after testing proofreading software extensively, we found most thesis writers will get value from Scribbr or QueText.

These tools check a thesis against published academic content. Scribbr is ideal as TurnItIn powers it and is open to anyone to use. We liked QueText’s DeepSearch tech.

Grammarly works everywhere and has a best-in-class writing assistant. The plagiarism checker is fast, if not as deep as other tools listed here.

Quillbot is a runner-up thanks to its citation manager. Try PaperRater if you’re short on funds. Your mileage will vary with the other options.

I worked as a professional sub-editor for several national newspapers and completed several proofreading courses. I also completed several post-graduate courses, including a Masters in Disability Studies at Trinity College Dublin, for which I wrote a forty-thousand-word thesis.

On Become a Writer Today, I worked with writing software reviewers to profile many of the best tools and apps, including the thesis plagiarism tools featured.

We regularly update this roundup of plagiarism tools. We test new features by checking articles, book chapters and blog posts for grammatical mistakes and other issues.

These articles and other writing samples range from several hundred to several thousand words. Typically, we test them using the web, desktop and browser apps and plugins.

Scribbr is the best alternative to Turnitin as it’s powered by Turnitin but anyone can use it. If you must use another tool, try Quetext. Its DeepSearch technology is ideal for plagiarism checkers for students in academia. Grammarly is good for general grammar and plagiarism checks.

Frequently asked questions

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker. Plagiarism checks can be bought separately — prices depend on the size of your document.

Similarities in your document are highlighted for quick and easy review. Each colour corresponds to a source in your Sources Overview at the right side of your report.

Information can often be found in more than one place. For this reason, other sources citing the same information you used can come up in your Sources Overview.

The important thing is to make sure you’ve cited the source of the material. Try to find the original source, but if you can’t find it, it’s best to cite the source where you found the information.

Scribbr’s free plagiarism checker estimates the risk of plagiarism by calculating the percentage of text in your document that’s similar to other sources.

A moderate or high risk of plagiarism means that the plagiarism software detected several similarities worth reviewing.

Note that similarities are not necessarily plagiarism. You will need to decide on your own whether your text needs revision or citation.

The free report tells you if your text contains potential plagiarism and other writing issues. The premium report gives you the resources you need to review issues in detail and resolve them.

Yes, Scribbr offers a limited free version of its plagiarism checker in partnership with Turnitin. It uses Turnitin’s industry-leading plagiarism detection technology and has access to most content databases.

Run a free plagiarism check

If you’re a university representative, you can contact the sales department of Turnitin .

If you’ve correctly cited all the sources you used, then you do not need to use a plagiarism checker before submitting your paper to your instructor. However, it is very easy to commit plagiarism accidentally, even if you’ve been very careful. To ensure that you didn’t forget to cite anything, you should use a plagiarism checker yourself.

A  plagiarism checker works by using advanced database software to scan for matches between your text and existing texts.

To help you decide which checker to use, we conducted in-depth research comparing popular plagiarism checkers to find out which one is best.

Best plagiarism checker comparison

Your work should not contain any  plagiarism . Even if your score is 1%, you will need to review each similarity and decide whether it’s necessary to revise your work.

But  contrary to popular belief, plagiarism checkers work by detecting not plagiarism, but similarities . Not all similarities found by the Scribbr Plagiarism Checker constitute plagiarism. Our check sometimes flags the following:

• Properly cited quotes
• In-text citations or your reference list
• Commonly used phrases

What should I do with a found similarity?

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

Here’s a guide to navigating plagiarism checkers and ensuring your writing is original:

Understanding Plagiarism Checkers:

• What they do: Plagiarism checkers are software programs that scan your text against a massive database of web pages, articles, and academic journals. They identify any significant matches, highlighting potential plagiarism.
• Peace of mind: Knowing your work is original reduces stress and avoids accusations of plagiarism.
• Catching unintentional mistakes: Even paraphrasing without proper citation can be flagged, prompting you to double-check your references.
• Not perfect: Plagiarism checkers are powerful, but they can’t catch everything. For instance, they may miss paraphrased content that retains the original meaning.
• Limited databases: Free checkers might have smaller databases, potentially missing less common sources.

Using a Plagiarism Checker:

There are several free and paid plagiarism checkers available online. Here’s a general process for using them:

• Choose a checker: Consider factors like features, database size, and cost. Free options are great for basic checks, while paid services might offer more in-depth analysis.
• Upload your text: Most checkers allow you to copy and paste your text or upload a document file.
• Run the scan: Initiate the plagiarism check and wait for the results.
• Analyze the report: The report will highlight any matches. Review each flagged section carefully.

Beyond the Checker: Avoiding Plagiarism

• Proper citation: Always cite your sources correctly, following the appropriate style guide (e.g., MLA, APA).
• Paraphrase effectively: Don’t simply copy and change a few words. Rephrase the information in your own words, but still cite the source.
• Focus on understanding: The goal of research is to learn and develop your own ideas. Don’t rely solely on copying others’ work.

Plagiarism is a serious offense that can hurt your academic or professional career. To avoid accusations of plagiarism, it’s important to use a plagiarism checker to ensure that your work is original.

Ensuring the originality of your content is essential, and the best plagiarism checkers mentioned above can assist you in avoiding the severe consequences associated with plagiarism.

By considering factors such as content database size, user interface, additional features, and pricing plans, you can select the most suitable plagiarism checker to meet your specific needs. Invest in these reliable tools to enhance your writing integrity and achieve peace of mind.

Many plagiarism checkers are available, so it’s important to choose the right one for your needs. In this article, we’ve compared the best plagiarism checkers of 2024 and helped you choose the one that’s right for you.

We hope this article helps you to choose the right plagiarism tool to check your thesis, research manuscript, and assignments.

Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

• Scans your paper against billions of sources.
• Identifies text that may be flagged for plagiarism.
• Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

• A chart or graph from another source
• A paraphrase of an original source
• Several sources’ ideas summarized into your own paragraph
• A direct quote
• All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level. You’ll be notified of which phrases are too similar to current research and literature, prompting a possible rewrite or additional citation. You’ll also get feedback on your paper’s inconsistencies, such as changes in text, formatting, or style. These small details could suggest possible plagiarism within your assignment.

And speaking of citations, there are also  EasyBib citation tools  available. They help you quickly build your bibliography and avoid accidental plagiarism. Make sure you know which citation format your professor prefers!

Great! How do I start? 

Simply copy and paste or upload your essay into the checker at the top of this page. You’ll receive the first five grammar suggestions for free! To try the plagiarism checker for free, start your EasyBib Plus three-day free trial.* If you love the product and decide to opt for premium services, you’ll have access to unlimited writing suggestions and personalized feedback.

The EasyBib plagiarism checker is conveniently available 24 hours a day and seven days a week. You can cancel anytime.  Check your paper for free today!.

If you are writing scientific papers or academic thesis, one of the most critical aspect of your work is avoiding and reducing plagiarism from your papers. In this post we will break down the most useful plagiarism checker for research work and journals. 

The recommendations in this article have a data-base of thousands of papers from medical, engineering and other domains and AI capabilities to offer plagiarism reports.

Recommendation Plagiarism Detectors for Research

• Turnitin (Only registered students and researchers can use it. Not available for public)
• Plagiarism Checker X ( Available in 7 languages including German; Used by top Universities and companies )
• Grammarly ( Grammar checker and Plagiarism detection tool; Now available on Mac and Windows )
• ProWritingAid ( Plagiarism and Grammar error correction; Loved by Millions of Authors, Writers and academicians )

Hunting plagiarism in research papers is more daunting than a personal website or a blog.

Where you can have a fair excuse and the luxury of <blockquote> , which help other search engines to know that you have copied online, you don't have such an option while working on your thesis. Here we are writing about the best software tools to prevent plagiarism in research work.

Plagiarism is unacknowledged copying or an attempt to misattribute original authorship, whether of ideas, text or results.

source: https://www.nature.com/authors/policies/plagiarism.html

There can be multiple ways to plagiarise your hard-worked content. We have already talked a lot about accidental plagiarism and ways to protect it in our previous articles.

You can also test your knowledge by taking a simple plagiarism quiz which will help you to understand and avoid plagiarism in a better manner.

Other is, as you know, intentionally. No matter, how are you messing up with the act, it will be equally offensive.

Steps to Avoid Plagiarism in Research Work

• The best way to stay original is: staying original. Don't get me wrong. All I want to say is, think with your own imagination. Paraphrasing is actually detectable if it is not done properly. Also, if you are doing it, you should not forget to add an in-text citation properly.
• Another important thing is to keep track of your work from the very beginning of your work. You can use cloud services like Evernote and Pocket to keep track of URLs, PDFs, Blogs, Websites, and Other Works.
• Unorganized papers often lead to plagiarism. You should be very careful while copying word-by-word. You can use "Quotes" to highlight the part which is copied with a source.
• Never trust Free services. Writing about the thousandth time, Do not use free tools. They will only lead you to false results and the risk of getting plagiarized with your own work. Paying someone to check your work on Turnitin will only lend you to hazard.
• If Your paper is an assignment, always do everything as instructed by the professor.

Best Plagiarism Checker Tools for Research and Journals

Without any doubt, Turnitin is a good tool to detect a similarity between the strings, whether it is a research work or an assignment. It has a huge database of research work and it is capable to find similarity in your content with the previous works.

A common myth about Turnitin is that it is a perfect tool. It is Not! Also, it is not a deciding tool   that you have actually plagiarized. Instead, it shows results to your professors for possible similarity among previously submitted work. That depends on the setting teachers are using. Only the examiner and you (human) can judge whether you have plagiarized or not.

Plagiarism Checker X

Plagiarism Checker X is the best alternative to Turnitin for many reasons. It provides some of the coolest features for students and professors. Some of them are bulk uploading, side-by-side comparison, automatic citation and multiple language support. It is the only tool on the planet which provides offline check after two consecutive checks.

You can play with the free version to test the waters before going for a premium one which is also available for less than $40 for a lifetime. It is being used by several universities and top companies as their standard tool.

PlagiarismcheckerX supports All Windows Platforms and you will be required to download .exe file to work with this plagiarism checker for academics.

Grammarly is one of the biggest companies working closely in education and industry. Hundreds of companies, schools, and universities are using Grammarly for proofreading, plagiarism checking, and learning English Grammar. They have a great database and constantly learning algorithms that are becoming better with time.

Not to forget, Grammarly is a safe tool (forget rumors) and they don't sell your data to anybody. With the provided browser extension, Android support, and native applications, it gives much power to you as an academician.

It supports macOS, Android, iOS, Windows, Google docs, and have a web application.

Plagiarisma.net

After a considerable amount of research, I came to the only Free tool which is safe to be used for research work. It uses Google Scholar search results to detect similarities in your content. Plagiarisma.net is able to detect more than 10 billion (as they claim) search engine results and it can be used from their website as well via their Windows application. But take this advice with a grain of salt.

Note that Plagiarisma only supports Windows operating systems.

ProWritingAid

Loved by some of the best selling writers, ProWritingAid is a decent grammar editor and contextual writing editor. In the premium version of the software, which is available on Apple devices, Windows, Google Doc, and Scrivener, has an integrated plagiarism checker.

ProWritingAid comes with fair pricing and great features, it can be on your radar if you are looking for a plagiarism checker for avoiding accidental pitfalls.

MOSS - Plagiarism checker for Code

(Measure of Software Similarity) or popularly known as MOSS is a tool that is very specific to the task of finding copied content for programmers. It is the (perhaps) best possible plagiarism checker ever created to detect plagiarism in software codes and programs. It was created in the Stanford labs in 1994. Since its inception, it is being used in several classrooms and research works to detect similarity in codes.

Bottom Line

The best way to protect your research is to keep it confidential. The above tools are tested and provide at most security to your data. Plagiarism can ruin your career and is unbearably frustrating. I hope the above tools will help you to write better assignments and get better grades.

Best wishes.

Plagiarism Checker by Quetext

Free plagiarism checker: how it works, enter text into plagiarism detection tool.

We make it simple. Just copy and paste all content from your document into our plagiarism checker and hit the ‘Check Plagiarism’ button to get started.

Evaluate text for plagiarism

Our plagiarism detection tool uses DeepSearch™ Technology to identify any content throughout your document that might be plagiarized. We identify plagiarized content by running the text through three steps:

• 1.) Contextual Analysis
• 2.) Fuzzy Matching
• 3.) Conditional Scoring

Accurate plagiarism results

After evaluating the text against billions of internet sources, you will be provided with a plagiarism score showing the percentage of text that is an exact or near-match to existing text online.

Resolve plagiarism risk and use citations

Our ColorGrade™ feedback feature highlights exact matches vs. near-exact or “fuzzy” matches with corresponding colors. From there, you can resolve plagiarism issues by deleting or altering the at-risk copy. Or, you can use our handy “Cite Source” feature to generate citations in MLA, APA, and Chicago formats and insert the citations directly into your document.

Plagiarism Checker Benefits

Whether producing original content or verifying that of others, there’s a lot to gain from using a plagiarism checker. Accurate, automatic detection of duplicate content facilitates the copy-checking process for teachers, students, content writers, and more. Results showing the exact percentage of plagiarized content allows users to see exactly how much text has been copied and where they need to re-word.

For Teachers

Before homework can be graded for quality, it must first be confirmed as original. Our easy-to-use tool arms teachers with a simple, effective way to verify and grade students’ work. Educators at all levels can benefit from ensuring academic integrity through a comprehensive plagiarism check. From K-12, all the way through higher education, teachers are faced with the task of verifying the originality of the work of dozens, if not hundreds, of students each year. Automating this process frees teachers up to focus on the quality of work, rather than be bogged down by its originality.

For Students

While the prevalence of academic plagiarism is on the rise, much of it is arguably unintentional. A simple, yet accurate and comprehensive, plagiarism checker offers students peace of mind when submitting written content for grading. It is much easier to do a quick check for potential plagiarism before submission rather than convince a teacher after the fact that your academic integrity is not in question. And Quetext even takes checking for plagiarism a step further, helping students identify and cite the source itself with our built-in citation generator.

For Copywriters

Plagiarism risk is not restricted to academia. Anyone tasked with writing for an individual or business has an ethical and legal responsibility to produce original content. On top of that, content writers are often tasked with producing content on topics outside of their wheelhouse, leaving them reliant on the work of others for their research. Our plagiarism checker gives content writers a quick and easy method to prevent copyright infringement. Checking even lengthy pieces of writing takes only a few minutes, keeping companies’ public content in check and writers’ integrity intact.

Types of Plagiarism

It’s important to understand that plagiarism expands far beyond just copying someone else’s work word-for-word. There are several different types of plagiarism that should be avoided.

Self-Plagiarism

Many believe that, as long as they produced the work at some point in the past, they can include it in future pieces. However, even if you were the original author, that original work must be cited in order to not be flagged as plagiarism. Treat your past self as a totally separate author; be sure to include all relevant citations and quotations, the same as you would for any other source.

Patchwork Plagiarism

Patchwork plagiarism is the act of piecing together a "patchwork" of existing content to form something new. Assembling unoriginal content in this manner often involves some paraphrasing, with only slight changes. This type of plagiarism can be tricky and can certainly occur unintentionally, especially in academia. Since academic writing is largely based on the research of others, a well-meaning student can inadvertently end up plagiarizing.

Mosaic Plagiarism

Mosaic plagiarism is synonymous with patchwork plagiarism. It describes the process of loosely rearranging or restating another's work without issuing proper credit. It can occur accidentally or intentionally. For authors, mosaic plagiarism endangers their academic integrity or reputation as a writer. For those checking content originality, such as teachers, mosaic plagiarism can easily appear to be original content, which can make mosaic plagiarism especially difficult to detect manually.

Accidental Plagiarism

Plagiarism doesn’t have to be intentional to still be considered plagiarism — even in early academia, where students are just learning how to properly cite others’ work. While there may be no ill intent from the student, most schools have policies explicitly treating accidental plagiarism the same as intentional plagiarism. Students are expected to know how to properly issue credit to other authors. Similarly, content writers risk damage to their reputation if they produce plagiarized content, regardless of intent.

Plagiarism Checker FAQ

What is plagiarism.

Plagiarism is representing someone else’s work as your own. In educational contexts, there are differing definitions of plagiarism depending on the institution. Plagiarism is considered a violation of academic integrity and a breach of journalistic ethics.

What percentage of a paper can be plagiarized (or copied) and still be considered unique?

Generally speaking, similar or exact copies of another source should be kept under 15% for the total text of the article/paper/essay. As a best practice, citations should be used whenever using another source word-for-word.

What’s the difference between deliberate and accidental plagiarism?

Deliberate plagiarism is purposely copying works from books, articles, webpages, or someone else’s paper and representing it as your original work. Alternatively, accidental plagiarism occurs in a few different ways:

• Incorrectly citing another person’s works
• Failing to paraphrase another person’s works - even when citing it correctly
• Reusing your own previous papers and inadvertently representing it as a new idea

What are the consequences of plagiarism?

The consequences for plagiarizing another person’s works vary. But broadly speaking, the types of consequences can be grouped by person and profession.

Plagiarism consequences for students

Maintaining academic integrity is a top priority for every educational institution. As already mentioned, ignorance of how to properly cite sources is not an excuse for plagiarism. It is the student’s responsibility to ensure they are submitting work that has not been plagiarized.

Failure to do so can result in disciplinary action, including an automatic failed grade, removal from a class, or expulsion from a school or university. Students who are allowed to continue at their institution following an act of plagiarism may encounter mistrust and additional scrutiny from teachers and instructors.

Plagiarism consequences for copywriters

Copywriters stake their reputation (and by extension, that of their client or company) on their writing. All copywriters must produce completely original content for their clients.

The consequences for plagiarism here are clear: Copywriters who plagiarize the content of others will quickly find it difficult to obtain paying assignments. Similar to academic situations, it is the copywriter’s own responsibility to ensure that their content is 100% original.

Plagiarism consequences for journalists

Journalists are held to exceptionally high standards of integrity in their writing. A journalist who produces plagiarized content jeopardizes the trust of their readers and publishers. Plagiarism can instantly reduce a journalist’s career by a large margin. The ethical and legal standards issued to journalists are clear: Produce original, well-cited content or find another field.

In the next step, the extracted text will be transferred to a temporary database and will be divided into individual sections according to language statistics.

The plagiarism checker then reads the individual sections and searches the World Wide Web for matches. In the last step, a plagiarism report will be generated, in which plagiarized areas are marked in color and the link to the original source is given. If you’re not sure why something has been marked as plagiarism, check out our blog post to find out more about what constitutes plagiarism . But don’t worry! Because 24 hours after using the plagiarism checker online, your data will be deleted – completely in line with data protection requirements!

Do I have to register for the plagiarism checker first?

No! It’s incredibly easy! You can just upload your document, choose your payment method, and then use the plagiarism checker without a user account or registering. Start your plagiarism check now.

Which sources will be used by the plagiarism software?

All publicly accessible online sources will be used in the plagiarism check. Databases where payment is required are excluded. If a book is online in a publicly accessible database, then the plagiarism software will also find this source. Have trouble organizing and citing your sources? Take a look at our blog posts. We have APA citation , Harvard referencing , and more.

What’s the difference between the BachelorPrint plagiarism software and Turnitin?

The BachelorPrint plagiarism software doesn’t save any uploaded work for data protection reasons, unlike Turnitin. Accordingly, we don’t rely on the same database as Turnitin.

However, our plagiarism software searches billions of publicly available sources on the World Wide Web.

Information : If the work is scanned for plagiarism in advance with Turnitin, and the university also uses Turnitin, there is a considerable potential risk for the writer. As Turnitin saves the uploaded work, this will then be in their database. If the university scans the same work on it, it will then be classified as complete plagiarism. This has already been heard of a few times. The student’s work therefore failed in the first instance, and they had to prove that they had written the document saved by Turnitin.

I haven't received an email with the plagiarism software. What should I do?

It’s possible that the email from the plagiarism software has gone into your spam folder. In extremely rare cases, our e-mail with the plagiarism report from the plagiarism software might have been blocked by your e-mail provider and haven’t been received. Please contact us at [email protected] . We will resend the plagiarism report right away.

Too few pages are shown in the plagiarism report. Why?

For an overview, only text passages that might contain plagiarism are shown in the plagiarism report. The other pages where no plagiarism is suspected will not be shown. So fewer pages in your plagiarism report is a good sign!

Why is a section marked as suspected plagiarism even though I have cited the source?

It’s possible that a section of text is marked as suspected plagiarism even though it has already been correctly cited, for example from a book. This happens if the software finds a further online source. In this case, the suspected plagiarism can be ignored and this serves merely as extra peace of mind. To learn more about properly citing your sources, read our blog post about how to cite a book .

Why should I use the online plagiarism software?

It mostly happens unintentionally. Mistakenly. Unknowingly. Due to time constraints. Even though every single student knows, or should know, that every source from a different author must be identified in an academic paper. Not complying with this principle is committing plagiarism. Therefore, you should use the online plagiarism software just to be sure.

There are well-known examples that indicate how rigorously academia deals with plagiarism. Writers of a Bachelor’s thesis, Master’s thesis, and other academic work didn’t have to fear being disqualified from their Ph.D. program or even public exposure. However, this is of little consolation to someone who has failed their bachelor’s thesis because of a few “forgotten” citations.
