Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier if you already pay Gemini. B-tier standalone.
