Kai's verdictA-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier if you already pay Gemini. B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
