Kai's verdictA-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.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
