Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
