AI Documentation Generator

Connect your GitHub repository and Pushpen automatically generates, updates, and synchronizes documentation on every push. No more stale READMEs or outdated API docs.

Documentation is the first thing developers check and the last thing teams update. Traditional doc generators produce a snapshot that rots the moment code changes. Pushpen takes a different approach: it lives alongside your repository, analyzes every push, and updates your docs incrementally. The result is documentation that always reflects what your code actually does.

The problem

Documentation degrades the moment you merge.

Manual updates don't scale

Every new endpoint, changed parameter, or refactored function creates a gap between code and docs. Teams that ship daily can't keep up with manual documentation.

Outdated docs destroy trust

Developers who hit errors because of stale documentation lose confidence in your project. Support tickets pile up. Onboarding slows down.

How Pushpen works

From GitHub repo to updated docs, automatically.

Pushpen reads your repository structure, parses source files, and builds a live documentation model that updates with every commit.

01

Connect your GitHub repo

One-click OAuth installation. Pushpen gets read-only access to your repository and pull requests.

02

Pushpen analyzes your codebase

AI scans your project structure, reads route definitions, extracts function signatures, and maps your documentation surface.

03

Push code as usual

No new commands or workflows. Every push triggers an incremental analysis of what changed.

04

Docs update automatically

Pushpen generates a PR with updated documentation. Review, approve, and your docs stay in sync forever.

FAQ

Frequently asked questions

How does an AI documentation generator work?

It analyzes your source code — routes, functions, schemas, and comments — and generates human-readable documentation. Pushpen goes further by running on every push so docs never go stale.

Can AI documentation replace a technical writer?

It handles the mechanical work: endpoint descriptions, parameter tables, changelogs. A technical writer can then focus on tutorials, guides, and high-level architecture docs that AI still struggles with.

Is my code sent to an external AI service?

Pushpen processes your code through its own models. Code is only used to generate documentation and is not retained or used for training.

What languages and frameworks are supported?

Pushpen supports most major languages and frameworks including Python, JavaScript, TypeScript, Go, Rust, Ruby, and Java. Framework detection is automatic for popular tools like FastAPI, Next.js, Django, Rails, and Express.

Do I need to change my workflow to use it?

No. Install the GitHub app, push code as usual, and Pushpen generates or updates documentation automatically. No new commands, no build steps, no manual triggers.
