Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
