It's been super helpful when checking sources on the internet to see if it was done by AI. The detector accuracy has been on point for me, so I use it to check news sources, and particularly social media to know what content out there I can actually trust

I do a lot of freelance writing for various organizations, a lot of which involves research around health and well being, something I have to be very meticulous about when it comes to stating facts. With AI becoming such an issue in the last year, I needed something that helped me identify if any of the research I was reading online was generated by AI so I will know to find other sources to ensure accuracy. The Copyleaks Chrome Extension was a life saver because I could easily check content right in the browser without having to jump around to various windows. Since I started using it a few months ago, it's only gotten better and operates more smoothly, so I appreciate that they are always working to improve and update the product. Definitely recommend.

AI detection is much more accurate than all others I have tested, is easy to use, and quick to provide results. Def. recommend.
