Best Free Plagiarism Checkers For Writing Unique Content

If you’re into blogging, content writing, and academic writing, then you will know how crucial is plagiarism checking. Plagiarised content can be harmful to your website as will negatively affect your blog SEO. Similarly, an academic thesis or a scientific manuscript should be free from all sorts of plagiarism.

Thankfully, a number of internet softwares are available that can instantly scan through the internet and compare your pre-written content with all published articles across the world, and show you the possible plagiarism involved.

While the popular grammatical error checking tool Grammarly includes an inbuilt Plagiarism Checker along with its premium version, it is not accessible for free. But don’t worry. I have put together a list of the best free plagiarism checkers online that can help you instantly scan any unintentional plagiarized content.

Here are some of the best free plagiarism checkers for writing unique content and prevent accidental duplications:


quetext plagiarism checkerQuetext is by far the best plagiarism checker available in the market. I personally use this tool to check plagiarism before publishing any posts. It has both free and paid plans. You can check your text for plagiarism, search the text for other errors in writing, and quetext will help you build citations and support you with any other writing issues. It uses DeepSearch™ technology to scan your documents at lightning-fast speed. Within seconds you can check your content for any plagiarism and errors.

The free version allows you to check 2500 words of content, and after that, you have to buy the paid plans. However, believe me, if you’re into content writing, then it’s worth buying. The paid plan costs $9.99 a month and allows you to check 1 Lakh+ word of content. For PRO users who have exceeded their monthly search quota, additional credit can be purchased directly from your account if you have exceeded your search quota.

Duplichecker plagiarism checkerThe free tool Duplichecker is one of the most popular. It also includes other automation related to the content, such as spellchecking, grammar checking, and plagiarism checking. The interface is simple to use. All you need to do is copy your content and paste it into the Duplichecker website and click on Check Plagiarism.  From there, all you need to do is wait a couple of minutes for the results to appear, and there is no need to provide an email address or get an account. The maximum number of words per search is 1000, but this doesn’t seem to be a big worry.

A free, easy-to-use, and effective plagiarism checker with an easy-to-follow interface. Its paid version starts from $10 to $200 a month, getting more searches for more dollars.

plagscan plagiarism checkerWhile PlagScan is mainly for students, it is also useful for online content. However, the interface is a little cluttered and requires you to create an account to check the plagiarism. During this ‘free trial,’ you receive 20 free credits to run 20 scans.

PlagScan keeps the import process simple by supporting URLs, local files, and plain text input. With additional information like word counts and dates, the scans are saved to your account so you can access them whenever you want.

PrepostSeo Plagiarism Checker:

prepostseo plagiarism checkerThis tool is pretty much similar to SmallSeotools checker. You don’t need to log in and Register to check the plagiarism. However, it’s not as accurate as Quetext paid tool, but it is still good for small corrections. You can also exclude quotes and URLs from the post as Quotes are something you can’t change from your post. I find this feature pretty useful.

Apart from the Plagiarism checker, the Prepostseo offers a Grammar Checker, Paraphrasing Tool, and word counter that will help you in some way.
