Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
