Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Still early. Manus is more flexible for less money.
