Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
