Ask HN: Request to add an [AI] tag to posts?

This is such a great website, but it's becoming less interesting by the minute.

Can we have a title detection system, similar to the existing automatic "[YEAR]" and "How to" → "" rules, which just marks a post as AI related?

I know this might be a far harder task than I think, since AI is now the defacto topic.

Or, can anyone suggest a Firefox addon that filters out post based on a blocklist of words?
