| Kai's verdict | A-tier for real-time. B-tier for everything else. Worth checking when news breaks. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | 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. |
