Kai's verdictB-tier. Still early. Manus is more flexible for less money.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. The right answer if you want open-source + terminal-native + model-agnostic.
