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.S-tier in its category. The first AI music tool I'd actually listen to.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
