Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for text-in-image. Use this for posters, Midjourney for art.
