| Kai's verdict | S-tier for text-in-image. Use this for posters, Midjourney for art. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for builders. The right primitives. What Kai is built on under the hood. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. |
