Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
