Penify (formerly Snorkell.ai)
Penify (formerly Snorkell.ai) is a GitHub and Bitbucket app that generates and updates code documentation when pull requests merge. It handles docstrings, API docs, and architecture documentation for Python, Java, TypeScript, JavaScript, and Kotlin repositories so teams spend less time writing docs by hand.
The app installs directly on your repository and tracks code changes after each merged PR. It identifies new classes and functions, refreshes existing documentation, and can analyze pull requests before they ship. A knowledge base and chat agent let product managers, analysts, and QA staff query the codebase in plain language.
Penify is built for development teams that want documentation to stay current without slowing down shipping. It suits backend engineers, platform teams, and technical leads who need accurate reference material that reflects the latest code.
