Kai's verdictB-tier. Still early. Manus is more flexible for less money.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
