Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier in its niche. The only one that actually gets emotion right.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.
