Wikipedia has a cheat sheet of well-known tells for identifying generated text. (With an appropriate warning not to over-index on minor ones as absolute proof) https://en.m.wikipedia.org/wiki/Wikipedia:WikiProject_AI_Cleanup/AI_catchphrases

The more detailed the list becomes, the easier it is to simply adapt AI generated content to avoid these things, eventually making it harder and harder to tell if something is written by AI.
