Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
