Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.
