I've seen a lot of talk on the SE metas (metae? metapodi?) about AI answers, but I haven't seen any methodology for detecting it. I've run a few answers (that looked suspicious: really well-written from new members) through an AI checker.

What is the formal approach for us (specifically as users, I don't have an interest in some secret SE algorithm) in detecting AI?

    $\begingroup$ Are you aware of the false positive error rate of such screens? I have not checked, but a post on main meta (admittedly old but still official) debates the usefulness of detectors and concludes their high error rate makes them unreliable. OTOH AI generation features tend so far not to be hard to discern and user flags and comments are welcome. $\endgroup$

I would encourage users to evaluate the quality of the answer. Currently, AI-generated answers are mostly not that good, so down-vote low-quality answers. If you are fairly certain an answer is AI-generated, flag it with "in need of moderator intervention", adding you suspect generative AI use.

Depending on the tools moderators have available and how much of a signal they give, we might delete the flagged answer. If we don't delete it, at least the score indicates it is not the best answer.

In cases where you have a better answer, I encourage you to post it. With enough eyes on the AI-suspected answer and on your answer, yours might float to the top.
