Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier if you already pay Gemini. B-tier standalone.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
