Kai's verdictS-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.B-tier. Still early. Manus is more flexible for less money.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
