Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier in its category. The first AI music tool I'd actually listen to.S-tier in the agent category. The first one I'd give to a non-technical friend.
