Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier for data teams. S-tier if you already live in SQL + Python.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
