Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier for social/casual. B-tier for serious work. Good entry point.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
