Having used AI to write docs before, the value is in the guidance and review.

I started out with telling the AI common issues that people get wrong and gave it the code. Then I read (not skim, not speed, actually read and think) the entire thing and asked for changes. Then repeat the read everything, think, ask for changes loop until it’s correct which took about 10 iterations (most of a day).

I suspect the AI would have provided zero benefit to someone who is good at technical writing, but I am bad at writing long documents for humans so likely would just not have done it without the assistance.
