Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier if you already pay Gemini. B-tier standalone.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
