| Kai's verdict | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
