Kai's verdictS-tier for solo + free. The best free option, hands down.S-tier in the agent category. The first one I'd give to a non-technical friend.B-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.
