Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Still early. Manus is more flexible for less money.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
