| Kai's verdict | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic. | 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. |
