I often ask for ai to give only grammar and spelling corrections, and then only a change set I apply manually. In other words the same functionality as every word processor since…y2k?
I sometimes also ask for justification of why I should change something which I hope, longer term, rubs off and helps me improve on my own.
Sometimes I use incorrect grammar on purpose for rhetorical purposes, but usually I want the obvious mistakes to be cleaned up. I don't listen to it for any of its stylistic changes.
