Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in its category. The first AI music tool I'd actually listen to.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
