Point your Pen. Comment. Improve.

AI builds it.
You stay in control.

Turn your vibe code into a wiki you can understand, review and improve.

  • In VS Code — connects your own Claude Code with your Markdown files. Point your pen, comment, and it changes the document or the code.
  • On the web — run reviews against your guides, bring your team in, and get their comments back in your editor.

I built it with AI. It worked.
But did I really understand it?

Pen Wiki in VS Code: a sentence selected, a comment typed on it, and the kinds of answer to choose from

One wiki. Two places.
Your Claude Code.

Your documentation connects your code, your AI, and your team.

1
In VS Code

Understand & Improve

Open any Markdown file, or let Claude create one from your code. Point to something you don't understand. Ask Claude to explain it — or change it.

2
On the web

Share & Review

Give others a link to your wiki. They explore and review your project without installing VS Code or Claude Code.

3
Back in VS Code

Act on feedback

Comments from the web appear in your editor. Reply yourself, or let Claude Code investigate, fix the issue, and update the documentation.

Review the changes. Keep improving.

More than documentation.

Claude Code can document your whole project. Three Markdown files, three ways to use them.

architecture.md
Understand your code

Let Claude explain your project's architecture, components and dependencies.

security-standards.md
Set your own rules

Describe how your project should work. Your standards, written in plain Markdown.

security-review.md
Review against your rules

Let Claude find gaps between your code and your standards. Fix the issues and verify the results.
