Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for solo + free. The best free option, hands down.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.
