Yes, they do work.

Pass enough of someone's work through one, such as Pangram with a low FPR, and you can gain confidence.

Add in your own intuition plus multiple scans of someone's work, plus any weird claims they make, and you can raise the certainy bar.

There is room for error, but come on. To say they don't work at all and you can't combine multiple methods to come to reasonable conclusions?

I'll accept it is with fault. The problem could be alleviated if people just were honest about the use of generative AI usage and others didn't judge so harshly the use rather than the outcome.

I said at the start I don't care if it was used. I just want honesty.
