Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Close second to Cursor. If $5/mo matters, start here.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
