| Kai's verdict | S-tier in its category. The first AI music tool I'd actually listen to. | S-tier for builders. The right primitives. What Kai is built on under the hood. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
