“In Grading your last three assignments I have opened my own account for Chat GTP [sic],” the teacher wrote. “I copy and paste your responses in this account and Chat GTP will tell me if the program generated the content. I put everyone's last three assignments through two separate times and if they were both claimed by Chat GTP you received a 0.”
Sigh. The big problem is while this is obviously very very silly, there are plenty of tools that claim to be AI detectors. They don't work.
