Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. HeyGen wins for creators, Synthesia wins for enterprise.S-tier for open-source model APIs. The default in this space.
