| Kai's verdict | S-tier inside Photoshop (Generative Fill). B-tier standalone. | A-tier. HeyGen wins for creators, Synthesia wins for enterprise. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier in its niche. The only one that actually gets emotion right. |
