Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier. Still early. Manus is more flexible for less money.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
