| Kai's verdict | B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | S-tier for text-in-image. Use this for posters, Midjourney for art. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
