| Kai's verdict | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. | S-tier for teachers. If you teach K-12, start here this week. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
