Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.
