Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Still early. Manus is more flexible for less money.
