Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.B-tier. Still early. Manus is more flexible for less money.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.
