Kai's verdictA-tier. HeyGen wins for creators, Synthesia wins for enterprise.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
