Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier in its category. The first AI music tool I'd actually listen to.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
