Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier. Category-defining UX. If you take notes in meetings, switch this week.B-tier. Still early. Manus is more flexible for less money.
