Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
