I am absolutely no fan of Twitter or its owner(s), but Grok* actually is pretty good at this overall. It usually concludes responses with some annoying pithy marketingspeak LLMese phrase but other than that the tone feels overall less annoying. It's not necessarily flattering to either the user who invoked it or anyone else in the conversation context (in the case of @grok'ing in a Twitter thread).

*Before and after the Hitler arc, of course.
