Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.A-tier for designer-led sites. S-tier if animations matter.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier. Niche but beloved. If you've outgrown Notion, try this.
