8 Popular Plagiarism Detectors To Consider For Your Content

There are several reliable plagiarism detection tools available that can help you identify copied or duplicated content. And some are to (additionally) help with detecting if something is written by AI or if it’s written by a human.

But before we dig into some of these available tools, just know that there is a gray area amongst some of the results they produce. As an example of that, some results with AI detection might say it’s written by AI – when in fact it’s (sometimes) not — it’s just close to another article.


Here are some of the best plagiarism detectors widely used:

Common FAQs About Plagiarism & AI Detection

Q: Does Google not want to see any AI content on your website/blog?

A: Google doesn’t care as long as it’s valuable. Read this article.


Q:  Should I just crank out articles and content using an artificial intelligence software and call it good because it looks good?

A: Absolutely not. Sure, it might look good right out the gate, but that doesn’t mean any of it is strategic for your brand, your SEO, or for conversion. You will need to manually do some quality assurance to ensure everything is on point.



Plagiarism Detector Tools Conclusion

When using any plagiarism detection tool, it’s important to keep in mind that no tool is perfect, and a manual review of the results is necessary to determine whether the flagged instances are actual cases of plagiarism. Additionally, each tool may have different features, limitations, and pricing structures, so it’s advisable to explore and compare them to find the one that best suits your needs.
