Kai's verdictS-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.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for solo + free. The best free option, hands down.
