Nanomachines son!

Well I think it's not a good idea to use these sketchy detectors but you do you I guess...

Yeah I did try them out before and GPTzero gives out false positives pretty frequently even saying that my past essays are AI generated even tho I wrote it myself and for GPT 2, it can be easily bypassed by rephrasing a few areas. As for asking students to explain the content in the essay, can't they just read and understand what chatGPT generated before submitting them? I think using these detectors can do more harm than good especially given the amount of false positives they give. But I guess students who use chatGPT to cheat are the types that are too lazy to proofread them so there's that.

Wait how are you catching them? Doesn't chatGPT give unique responses and what hard evidence do you have?

The student can edit it into their style or feed their past essays into chatGPT and write a new essay mimicking how they write. They can also just read their essays and learn the information contained inside them although I highly doubt they would.

Even if they were, it's pretty unrealiable. I tried using GPTzero and it marked ALL of the essays regardless of it being written by a human or chatGPT as AI generated. And what's to stop students from using GPTzero to edit their AI generated essays until it's detected as human?
