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 for local inference. If you care about privacy or want to tinker, install this today.A-tier in its niche. The only one that actually gets emotion right.
