Point your pen. Comment. Improve.
AI builds it.
You stay in control.
See how your app works, what changed, and what needs fixing.
Powered by your own Claude Code, right inside VS Code.
I vibe-coded my apps. They worked.
But did I really understand them?
Run it again.
See what changed.
Your project changes. Pen Wiki helps you keep up.
Check your project
Claude reads your code and creates a clear report about your features, architecture, security, or anything else you want to understand.
Check it again
After your code changes, run the same check. Pen Wiki compares the results and shows what's fixed, new, or worse.
Decide what to fix
Point at a finding, leave a comment, or ask Claude to fix it.
Review the plan, approve the change, and run the check again to verify the result.
Point. Comment. Improve.
Your rules. Your Claude. Repeatable results.
Write once. Run whenever you need.
A Guide is a Markdown page that tells Claude what to check or document.
Run it against your project today, next week, or after a release. Each run creates a report you can review and compare with earlier results.
What can you do with Guides?
Document its features, architecture, components, and dependencies.
See what was added, changed, or removed since the previous run.
Discover new risks, resolved issues, and problems that still need attention.
Compare your code against your own architecture, security, or quality rules.
Check what changed, what passed, and what still needs attention.
Your guides and reports are Markdown files. Keep them with your project and use them again.
From findings to fixes.
Found something that needs attention?
Point at it in your report and choose Fix with Claude.
Claude shows its plan and waits for your approval before making changes on a separate branch.
Review the changed files and test results, then run your Guide again to confirm the issue is resolved.
You decide. Claude does the work. You verify.
