| Kai's verdict | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | 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. | A-tier for creators training custom looks. B-tier for general use. |
