Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier if you already pay Gemini. B-tier standalone.
