| Kai's verdict | S-tier inside Photoshop (Generative Fill). B-tier standalone. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for realtime. If latency matters more than voice catalog, start here. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. |
