| Kai's verdict | 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. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | A-tier for creators training custom looks. B-tier for general use. |
