Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier for realtime. If latency matters more than voice catalog, start here.
