Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.A-tier in its niche. The only one that actually gets emotion right.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. Niche but beloved. If you've outgrown Notion, try this.
