Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
