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 No more stale READMEs or outdated API docs.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.
Start freeThe problem
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.
Developers who hit errors because of stale documentation lose confidence in your project. Support tickets pile up. Onboarding slows down.
How Pushpen works
Pushpen reads your repository structure, parses source files, and builds a live documentation model that updates with every commit.
One-click OAuth installation. Pushpen gets read-only access to your repository and pull requests.
AI scans your project structure, reads route definitions, extracts function signatures, and maps your documentation surface.
No new commands or workflows. Every push triggers an incremental analysis of what changed.
Pushpen generates a PR with updated documentation. Review, approve, and your docs stay in sync forever.
Features
Auto-generated README that reflects your current API, install steps, and usage. Updates when your project changes.
Endpoint listings, request/response schemas, authentication requirements — extracted from your route code.
Commit messages translated into categorized, human-readable release notes following Keep a Changelog format.
Quick-start guides and setup instructions generated from your project structure and dependencies.
Contribution guides, environment setup steps, and architecture overviews tailored to your repository.
Suggestions for docstrings and comments based on function signatures and implementation patterns.
FAQ
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.
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.
Pushpen processes your code through its own models. Code is only used to generate documentation and is not retained or used for training.
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.
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.
