Kai's verdictA-tier. HeyGen wins for creators, Synthesia wins for enterprise.S-tier for text-in-image. Use this for posters, Midjourney for art.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
