Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
