The accuracy just isn’t there, which isn’t surprising. I’m feeding it Star Wars reviews from both ChatGPT and IMDb, and for sure the answers are correlated. The false negative rate is OK, although I’ve hit plenty of them. But man, it sure does think a lot of people were using ChatGPT to write reviews back in the 2000s. Again, it’s definitely correlated, even strongly correlated, but that’s not good enough for plagiarism detection. You can’t go accusing students of academic dishonesty based on a tool that gets it wrong multiple times on a couple dozen samples.
