A good use I've seen for AI (or particularly ChatGPT) is employee reviews and awards (military). A lot of my coworkers (and subordinates) have used it, and it's generally a good way to fluff up the wording for people who don't write fluffy things for a living (we work on helicopters, our writing is very technical, specific, and generally with a pre-established template).

I prefer reading the specifics and can fill out the fluff myself, but higher-ups tend to want "how it benefitted the service" and fitting in the terminology from the rubric.

I don't use it because I'm good at writing that stuff. Not because it's my job, but because I've always been into writing. I don't expect every mechanic to do the same, though, so having things like ChatGPT can make an otherwise onerous (albeit necessary) task more palatable.
