Let’s review each of these tools in detail below!
1. Quetext
Quetext is another free plagiarism checker that writers can swear by. Its powerful technology finds sources of plagiarised content within minutes.
Using Quetext is also super easy. You only need to visit the site, paste your content and click on check for plagiarism tap. The free version does not support any other text formats. But copy-pasting does the work without making you feel the need for other text upload choices.
However, the free version only allows you to check 500 words at a time, which is a bit of a bummer for those who want to check lengthy documents.
While testing the tool, I checked my text in different fragments, which took some time but served the purpose.

Duplichecker has a clean user interface that makes using the tool even easier. You can copy and paste the content or upload .tex, .txt, .doc, .pdf, .rtf, .docx, and .odt files. The tool also has a free grammar checker, which is an added benefit.
My only complaint with Duplichecker is that the tool is a little slow. It takes a bit longer to complete scanning the whole text.

It reviews your file against its huge database and brings your original sources of the plagiarism. The color-coded format makes it easier to identify sentences or paragraphs that contain plagiarism and fix it quickly.

Final Thoughts: Duplichecker is The Best Free Plagiarism Checker
Here is an extensive list of free plagiarism checkers to ensure your written texts are 100% authentic and original. My top three picks are SmallSEOTools, Duplichecker, and Quetext because of their accuracy, simple user interface, and support for multiple text formats.
Even though the free versions of all these tools have some limitations, they do the job of detecting copied content and preventing claims of publishing plagiarized content.
FAQs
Duplicker, Quetext, Small SEO Tools, Plagiarism Checker, and Unicheck are a few free, very accurate tools.
Your text needs to be 100% original, and you must not ignore even a single percentage. Review the result to find out the source and what changes you should make to eliminate even that 1% of copied text.
Yes, you can use Scribbr plag checker for free, but it has word limitations and shows the full report only when you purchase the premium plans.
No, self-plagiarism is also strictly prohibited and must be avoided at all costs.
