| Kai's verdict | S-tier for solo + free. The best free option, hands down. | S-tier inside Photoshop (Generative Fill). B-tier standalone. | S-tier for builders. The right primitives. What Kai is built on under the hood. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. |
