I would actually agree with that, too. Grammarly certainly isn't perfect (it still occasionally struggles with the nuance of some idioms or proper nouns), but it does better than LLMs (I use MacWhisper with its "CleanUp" AI prompt for dictation). But Grammarly's inline use is actually pretty handy (even in this text box, I pause typing for a moment, and there's a Tab prompt that will auto-edit my text live).
