Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier for data teams. S-tier if you already live in SQL + Python.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.
