Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
