Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
