Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
