| Kai's verdict | 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. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. |
