Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for solo + free. The best free option, hands down.S-tier in the agent category. The first one I'd give to a non-technical friend.
