What I've done a few times is have the AI provide feedback, and then I rewrite myself based on the feedback. So I don't use what the AI suggests directly, just the essence if I agree.

That's a good approach. My sin is that if I like the sentence, I keep and don't rewrite. Because if I see it is good, I don't feel I should. And probably I don't see that "prose" is bad each time it is indeed bad.
