Kai's verdictS-tier for solo + free. The best free option, hands down.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.A-tier. HeyGen wins for creators, Synthesia wins for enterprise.
