Kai's verdictA-tier. HeyGen wins for creators, Synthesia wins for enterprise.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
