Kai's verdictS-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.B-tier. Still early. Manus is more flexible for less money.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
