I'm incredibly impressed with this software. It's a must-have if you want your writing to be genuinely original. Use it for anything—work, creative writing, or class assignments—and you'll never face issues with AI detection or plagiarism again. give it a go!

I wish they would provide the ability to give 0 or negative stars. This extension is wholly unreliable. The Share button does not function most of the time and consistently fails due to unknown errors. Do not waste your time with this extension or GPTZero for that matter. Google its reliability as an AI checker.

Was great, but no longer working for some reason. 1/5.
