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.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
