That's not the kind of thing I'd trust to a language model: I'd expect it to persuade me to change something correct to something incorrect more often than it catches a genuine error. But ymmv, I suppose.
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.
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.
