Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
