Turn AI-generated code into something you and others can understand, review and improve —
in your editor, with your own Claude Code. On the web, when others should weigh in.

“I vibe coded it — and, as usual, realized I don’t understand so many things in it.”
One loop, where you already work. Pen View opens any Markdown file in VS Code the Pen Wiki way: point at a sentence, a picture or a diagram, say what should happen, and your Claude Code chat does it — in your repo, with your permissions, nothing running in the background. Team mode puts the project on the web, so the people who never open an editor can read, comment and review it; their comments come back to your Claude Code here.
