Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier if you already pay Gemini. B-tier standalone.
