  1. hedgehog
    Good one

    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.

    👍 Pros:    Fast|Accurate
  2. Go longhorns
    · Bachelor of Computer Science at UT Austin ·
    By far the most detailed AI detector I've ever used

    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. So, Polygraf was the only one that showed that I had used AI but it was Grammarly.

    👍 Pros:    Shows whichai you used|Shows and highlights the section of the ai content|Shows humanized content
    👎 Cons:    File upload was not available when i was using it|Their website can be a little more student friendly
