Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-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.B-tier. Still early. Manus is more flexible for less money.
