ProWritingAid is another heavy hitter that aims for world-class status. As one of the best grammar and plagiarism checkers, ProWritingAid is perfect for novelists, authors, and creative writers. The tool checks manuscripts, literary works, and other forms of full-length materials. It also tests for proper punctuation, grammar, and style issues.

The 11 Best Plagiarism Checker tools in 2021 (4)

It works right inside MS Word, which makes it very handy to use. It also integrates with Google Docs and Scrivener for easy access. ProWritingAid is compatible with Windows, Mac, and integrates with Chrome and Apple browsers. However, ProWritingAid is somewhat pricey at $10 for ten scans per month.

  • Compatible with all browsers.
  • Checks full-length manuals, manuscripts, and even novels.
  • Helpful integrations for Scrivener and Google Docs.

⛔️ CONS:

The Best Plagiarism Checker Overall

In the plagiarism checker contest, Grammarly wins the race. The program uses sophisticated algorithms to check for proper grammar, punctuation, tone, and plagiarism. Grammarly also checks for conciseness, readability, and also suggests vocabulary enhancements, and genre-specific writing style tips. They have three pricing plans for the Premium service (monthly, quarterly, and annually).

The 11 Best Plagiarism Checker tools in 2021 (5)

Grammarly works on the web, or you can download an app to your phone, tablet, or other devices. They also offer plug-ins for most browsers and email clients, so Grammarly is continuously checking your content, whether you are drafting a text message, emailing, writing a contract, or putting together a Word document. Grammarly basically always has your back!

When checking copy for free, you can simply paste the text into Grammarly’s plagiarism checker tool and see the results. Grammarly is in partnership with ProQuest’s academic databases and relies on them as a backbone for the plagiarism piece of their software.

Grammarly’s plagiarism checker is by far the most accurate. Writing professionals and publishers swear by Grammarly’s plagiarism checker for accuracy. Although you can scan text for free, if you want to review the full results, and get access to all the fancy tools, you will need a paid plan. Grammarly offers three-tiered levels to choose from.

  • Works on the web in any browser or using an app.
  • Easy to use.
  • Helpful for academics (uses ProQuest’s academic databases) to check for plagiarism.
  • Most accurate plagiarism checker.

⛔️ CONS:

  • Need a paid plan to get all the benefits.

3. Copyscape

Best for Bulk Plagiarism Checking

Another plagiarism checker online that you can try out for free is Copyscape. You can enter a URL and let it compare the content on that page to the rest of the web. The free version is fine if that is all you need to do, but the Premium version offers a lot more bang for your buck.

The 11 Best Plagiarism Checker tools in 2021 (6)

Copyscape includes things like bulk checking, managing plagiarism cases, the ability to copy/paste text to evaluate, testing your entire website at once (up to 10,000 pages), and other tools like an API to check content on your site automatically.

They charge 3 cents per search (up to 200 words) and then another 1 cent for each additional 100 words. Copyscape may be a solid alternative to Grammarly, but if you need to check a lot of content, it could get pricey quick.


  • Built-in, side-by-side comparison tools.
  • Super easy to use.
  • Quite effective at detecting plagiarism.

⛔️ CONS:

  • Affordable even for students on a budget.

  • Accurate.
  • Easy to use.
  • Doesn’t save your documents (privacy) in their database.

⛔️ CONS:

  • The free version limits you to 1 page.
  • Lacks advanced editing tools.

5. Duplichecker

Best Free Plagiarism Checker

Another great contender is Duplichecker, which works best for teachers, students, and budding, young writers. It’s completely free, so you don’t have to pay a dime to use it. To use Duplichecker, you only need to copy and paste your text in and click the button to run the process.

The 11 Best Plagiarism Checker tools in 2021 (8)

Some of the tools you can use with Duplichecker are a plagiarism checker, a word counter, spell checker, and grammar checker. The interface is a little old-school, but the system works well, and again, it’s entirely free to use. The only limitation is you can only check 1000 words at a time.

  • Great for students, teachers, and young writers.
  • Super easy to use.

⛔️ CONS:

  • Works on all web browsers.

Another very effective way to check your text for plagiarism is SmallSEOTools. It is not as powerful or effective as Grammarly, but it is free and includes some bonus features like a grammar checker, word counter, spell checker, paraphrasing tool, and a language translator.

They even have a whole cache of SEO tools to help with keywords and density when creating content geared towards website traffic building.

⛔️ CONS:

  • Ad-heavy website.
  • Not super intuitive to use.
  • Not as effective as other plagiarism checkers.

8. Copyleaks

Everyone has competition, and Copyscape’s worst enemy is Copyleaks. Not only does Copyleaks scan the internet for any duplication of your content, but it also acts as a copyright protection tool. Even if your content comes out clean, you may find that your original text shows up elsewhere on the internet because someone borrowed it without your permission.

The 11 Best Plagiarism Checker tools in 2021 (11)

One of the strengths of Copyleaks is that it finds those indiscretions and points them out to you so you can address them. The program allows you to check 100 pages/essays at a time, so it works great for teachers. They have a mobile app and a language translator, but you are limited to only 2500 words in a month unless you pay for the premium version.


  • Check 100 pages at a time (great for teachers).
  • Mobile app included.
  • Built-in translations.
  • Copy protection tool.

⛔️ CONS:

  • The free version limits you to 2500 words per month.
  • Paid business plan limits you to 100 pages per month.

Although not the best plagiarism checker around, Quetext is a very good alternative. It is simple to use and offers a free trial. However, the free trial is limited to only 500 words.

Quetext compares documents against online sources and books but not scholarly articles, so it’s missing a big piece of the puzzle. That makes it much less useful for teachers and students.

The 11 Best Plagiarism Checker tools in 2021 (13)

It may work fine for other applications, but without an extensive database to compare text against, it might miss things that other plagiarism checkers will not. If your needs are simple, Quetext may work for you.

What is a Plagiarism Checker?

A plagiarism checker is online software that checks a sample of text against thousands of online sources, books, academic articles, and scholarly papers looking for verbiage that has been re-used or stolen without permission. Good plagiarism checkers can find even nuances that indicate stolen content. Most charge a fee, but you can also use some plagiarism checkers for free.

Why Use a Plagiarism Checker?

Most people use a plagiarism checker to review content to make sure no part of it has been plagiarized. Sometimes academics use them to ensure that students have cited references and quotes correctly.

Benefits of Using Plagiarism Checkers

There are many benefits to using a plagiarism checker. The most common reasons someone would use a plagiarism checker are:

  • Ensuring the uniqueness and originality of content provided by others.
  • Checking your own writing to make sure you aren’t plagiarizing anyone else’s work.
  • Scanning for paraphrasing and re-using content without citing proper references.
  • Use the bonus tools like grammar, spelling, usage, wordiness, style, and punctuation correction.

Best Plagiarism Checker FAQS

What is plagiarism in simple words?

According to the Merriam-Webster online dictionary: to “plagiarize” means: To steal and pass off (the ideas or words of another) as one’s own. To use (another’s production) without crediting the source. To commit literary theft. In the simplest of terms, plagiarism is a fraud, and the consequences can be very serious.

What are the four types of plagiarism?

There are four different types of plagiarism: direct, self, mosaic, and accidental. Direct implies that the writer knew they were copying. If you re-use the content of your own that has already been submitting, that is self-plagiarism. Mosaic is when someone takes bits and pieces of a bunch of different articles and pieces it together to make it seem unique. Accidental is just that, someone forgets to cite a reference correctly or give credit to the original author.

What software can I use to check plagiarism?

There are dozens of tools out there, and the information may be confusing. To make things easier, check out our list of the best plagiarism checkers to help narrow it down to find the best plagiarism checker for you.

Which plagiarism checker is the best?

Most online users rate ProWritingAid as the best online plagiarism checker. Coming in a close second is Grammarly and following on its heels, Copyscape and Duplichecker. Some of these are free or offer free trials, and some require paid subscriptions.

Is there any free plagiarism checker?

Yes, there are a few free plagiarism checkers, but most carry limitations such as word count or how often you can use them. The paid versions are typically much more robust and helpful. Depending on what you need, there is probably a subscription plan that will work for you.

What is the best free plagiarism checker?

The best free plagiarism checker depends on what you need it for and how you intend to use it. Grammarly stands out as a leader in the industry, but you can also get good results using ProWritingAid and others like Copyscape and Duplichecker.

Is the plagiarism checker reliable?

Most top plagiarism checkers are reliable, but the accuracy level will depend on the checker you use. Some are better than others, and you might want to check reviews and compare stats before signing up for a plan.

What is a good plagiarism score?

Typically, you would hope for a 0% score, which would mean the entire document was plagiarism-free and completely unique. However, most editors and academics consider anything less than 15% to be okay in terms of acceptability.


Depending on your needs, one or a combination of the tools above should give you everything you need to make sure your content is error and plagiarism-free. Most will help you clean up any mistakes and enhance your verbiage so that you sound your best no matter what you are writing.
