| Kai's verdict | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | S-tier inside Photoshop (Generative Fill). B-tier standalone. | A-tier. Close second to Cursor. If $5/mo matters, start here. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. |
