Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for solo + free. The best free option, hands down.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
