How to Choose the Best Plagiarism Checker?

Every plagiarism checker is the same while also being different at the same time.

But the difference is created by how they allow users to use their facilities and how they make plagiarism checking less time-consuming. Thus, choosing the best plagiarism checker is of utmost importance for a blogger, writer, student, website owner, business person, or anyone who creates, proofreads, or publishes content.

Free Doesn’t Mean Cheap

Many people think that if a product or service is free, it is not worth using as it must be of low quality. But, it doesn’t hold true in the case of Plagiarism checkers as there are some wonderful checkers which are free of cost and work better than many paid checkers. Duplichecker is an example. So, check a product based on its features, not on its price.


English is the universal language, but when you create content for your local audience, you need a plagiarism checker that can understand your language. Scribbr supports 20 languages, while Plagramme supports 129 languages. If your content is multilingual, so should be your plagiarism checker.

Fit for All

There are some checkers that are free for educators. Some are for students, but businesspersons can’t use them as their databases mostly consist of scholarly articles and books. Some don’t have any scholarly articles at all. So, choose a plagiarism checker tool that can aid a blogger and work for a business organization, one that can help a student write a plagiarism-free paper while assisting the educator in detecting students’ tricks. It should be fit for all.

Multiple File Format

You don’t want to pay for a checker that only supports a particular file format. What if you have to check an epub file but your checker doesn’t support it? Paying several dollars for such a service is not impractical. A good plagiarism checker should support multiple file formats, including doc, docx, txt, epub, html, RTF, etc.
