Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
