Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Still early. Manus is more flexible for less money.S-tier for builders. The right primitives. What Kai is built on under the hood.
