Kai's verdictA-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-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. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
