Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. HeyGen wins for creators, Synthesia wins for enterprise.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for builders. The right primitives. What Kai is built on under the hood.
