This tool has one of the best ai (model) detectors, it really saved me when I was submitting my essay (it was 87% AI lol). Extension + web version is convenient, especially for students.
I transitioned from Turnitin to gptzero to Polygraf. they were all useless, as I got almost suspended due to my school almost failing me for using Grammarly. I can almost swear that that I did not use any other thing....
