Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
