Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier for text-in-image. Use this for posters, Midjourney for art.
