Top 5 Best Free Plagiarism Checkers Online

1. Grammarly Plagiarism Checker

One of the best free plagiarism checkers online that I personally use every day is Grammarly. It is by far one of the most accurate plagiarism checkers you can find online.

However, since Grammarly is a paid tool, you cannot expect much from its free plagiarism checker online. It only provides limited information, which might not be enough for you to decide on whether or not you should push the content.

Grammarly is highly accurate when it comes to plagiarism detection. It helps you remove plagiarism word by word. Moreover, it protects your data, as it is one of the most reliable and trusted tools in the market.

Overall, Grammarly is one of the best free plagiarism checkers available online, but it comes with 10,000 words in the free version. But if you think that the free version is working accurately for you, I would suggest you upgrade to the paid version, which provides accurate information.

2. Quetext Plagiarism Checker

Upnext on the list that I trust the most and I believe provides the most accurate information besides Grammarly is the Quetext Plagiarism Checker.

Sometimes Quetext also left Grammarly behind when it comes to checking plagiarism. This is because Quetext uses word-to-word AI detection algorithms. On the other hand, all the other plagiarism detectors detect plagiarism sentence to sentence. This gives Quetext an upper hand and makes it the best free plagiarism checker online.

However, everything best has limitations, and so is the case with Quetext; it ain't free like Grammarly. It comes with paid plans, and the basic plan costs $8.80 per month, which is reasonable if you do a lot of plagiarism checking online.

3. PlagiarismDetector.net

If you are looking for a completely free plagiarism checker online with a minimal user interface and fewer ads, then look no further than PlagiarismDetector.net.

PlagiarismDetector allows you to check a document by uploading it to its site or simply pasting the document URL for hassle-free plagiarism checking.

I have run multiple tests on PlagiarismDetector.net, and as far as my testing results, it is one of the best free plagiarism checkers available online in 2024.

You can compare it to other free plagiarism checkers like Duplichecker and Small SEO Tools' plagiarism detectors and it provides far more accurate results than those free checkers.

PlagiarismDetector.net uses a technology called "deep search," which helps us achieve those great results. While it's a completely free-to-use tool, and you can scan up to 25,000 words per month with the tool without even creating an account on the site, if you do more than that, consider upgrading to the premium plans.

4. CopyLeaks Plagiarism Checker

CopyLeaks plagiarism checker is one of the most underrated plagiarism checkers in the market. This plagiarism detector uses advanced AI and machine learning technologies to detect plagiarised content. The cherry on the cake is its broad support for over 100 languages, which isn't available in any other plagiarism detector out there.

The fact that many reputed universities and companies take use of Copyleaks Plagiarism Checker makes it one of the best free plagiarism checkers online.

Even though it's free, it has limitations with its free plan. However, you can upgrade to the monthly plan, which costs $8.99, which is very reasonable for the accurate results it offers. You can make use of Copyleaks, even if you are a developer, with its extended API support for cloud computing.

With the CopyLeaks free plan, you can scan up to 20 pages per month, and you can even detect whether or not the content is written by AI, which is another amazing feature of this tool, not found in any other plagiarism checker.

5. QuillBot Plagiarism Checker

QuillBot is an excellent plagiarism-checking tool. While mainly it offers other services like paraphrasing, refining, and improving your content. Over time, it has developed its plagiarism checker, which is breaking the internet right now with its mind-boggling results.

The sad part is that QuillBot charges you $8.33 with its monthly plan if you want to utilize all the premium features of the tool, including the paraphrasing tool.

Either you can copy and paste your text, or you can also upload various types of files, including PDFs, DOCs, TXT, and even HTML. Similar to CopyLeaks, Quillbot has also extended its support for over 100 languages, making it one of the best free plagiarism checkers online.
