Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for builders. The right primitives. What Kai is built on under the hood.
