Kai's verdictS-tier for realtime. If latency matters more than voice catalog, start here.S-tier for designers. The only one that takes vectors seriously.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
