Kai's verdictA-tier. HeyGen wins for creators, Synthesia wins for enterprise.S-tier for designers. The only one that takes vectors seriously.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.
