Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for fast prototypes. Competitive with Lovable — try both.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
