Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
