Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for builders. The right primitives. What Kai is built on under the hood.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
