Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.B-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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
