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.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.B-tier. Still early. Manus is more flexible for less money.
