Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for builders. The right primitives. What Kai is built on under the hood.
