Kai's verdictS-tier for realtime. If latency matters more than voice catalog, start here.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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
