Kai's verdictA-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.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
