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.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
