Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
