Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
