Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for builders. The right primitives. What Kai is built on under the hood.
