Hmm, can I RegEx this?

[\s-]AI[-,\.\s]

This is assuming it’s not at the start of the article.

EDIT: Thinking about it 2 more seconds, this might actually be more precise:

[\W_]AI[\W_]

Doing more, like \WAI would filter words like “ailment”. Haven’t found a word matching AI\W yet, but I’m careful atm.
