Kai's verdictS-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier for sales teams. B-tier for solo users.
