| Kai's verdict | A-tier. Close second to Cursor. If $5/mo matters, start here. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for ops automation. B-tier for simple copy (use Claude). | S-tier for builders. The right primitives. What Kai is built on under the hood. |
