Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
