Documentation Generator

Pushpen generates README files, API documentation, changelogs, and onboarding guides from your actual source code. Every doc is generated from what your code actually does — and stays updated with every push.

Most documentation generators produce a one-time snapshot. Pushpen is different: it runs continuously against your repository, detecting changes and producing targeted updates. Your README reflects your current API. Your changelog captures every release. Your onboarding guide matches your actual setup process. Documentation stops being an artifact and starts being a live artifact of your codebase.

The problem

Documentation is the first thing to rot.

One-time generation isn't enough

Most teams generate documentation once at release and it immediately starts decaying. A week of commits later, the docs no longer match the code.

Documentation debt accumulates silently

Unlike technical debt in code, documentation debt has no compiler warnings. It accumulates until a new hire spends three days debugging against outdated setup instructions.

How it works

From repo to docs, continuously.

Pushpen connects to your GitHub repository, analyzes your codebase, and generates documentation across the full surface of your project.

FAQ

Frequently asked questions

What types of documentation can Pushpen generate?

Pushpen generates README files, API documentation, changelogs, release notes, onboarding guides, developer contribution docs, and inline docstring suggestions. It covers the full documentation surface of a software project.

Does Pushpen work with any programming language?

Yes. Pushpen supports Python, JavaScript, TypeScript, Go, Rust, Ruby, Java, and many more. It automatically detects your project structure and adapts the generated documentation to your language and framework conventions.

How does Pushpen keep documentation up to date?

Pushpen runs on every push to your repository. It compares what changed against the existing documentation and generates targeted updates. Instead of rewriting everything, it produces incremental PRs that reflect only what changed.

Can I use Pushpen with private repositories?

Yes. Pushpen works with both public and private GitHub repositories. Code is read-only and never stored or used for model training.

How is this different from a static site generator like Docusaurus or GitBook?

Static site generators require you to write and maintain Markdown files manually. Pushpen generates the content for you from your actual code and keeps it synchronized. You can still use Docusaurus or GitBook to render the output — Pushpen handles the content creation and maintenance.
