Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
