| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | S-tier inside Photoshop (Generative Fill). B-tier standalone. |
