Kai's verdictS-tier for speed. When latency is the product, start here.B-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 multilingual video. If you sell courses or speak at events, this is a cheat code.
