Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
