Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier for designer-led sites. S-tier if animations matter.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
