  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

    · 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

    Recently, I've seen lots of posts about VS Code extensions. But did you know that many of the posts are outdated? How, you might ask? They were only shared yesterday! Well, let me explain. Many posts in the listicle format are AI-generate. ChatGPT's training makes it tend to write about a few general topics when you ask it “write an article for my coding blog”.
