AI can take a rough draft, clean it up and shorten it as much as you want. The suggestions very often expose ambiguities in the original text. If you think the LLM got it wrong, it’s nearly often the LLM overreading some feature of the original that you failed to catch, which is precisely what you’d want out of your proofreader.

Yes, LLMs reduce the individual charm of prose, but the critique itself carries a romantic notion that we all loved the idiosyncratic failures of convention and meaning which went into highly identifiable personal styles, and which often go missing from LLM-edited work.
