I have seen examples that shows otherwise, including from a client that tested it extensively by paying people who thought they were paid to help detect AI generated content. They did little more than what I described. It works very well. Some people still insist they are able to tell the difference, but in the tests I saw, people did little better than random chance.

Some of it you could probably tell with statistical analysis, but actualy people are far worse at judging whether content is AI generated than they think they are.

If you need to beat an AI testing tool, you need to do marginally more work than to stop people from recognising it, but not all that much.

The nature of it is that you don't "see" most of the stuff that is well done because few people want to talk about it.
