Penify streamlines the documentation process for Git repositories by automating it. Whenever a code change is merged into the "main" branch, Penify leverages a Large Language Model to create documentation that reflects the modifications made. This automation encompasses various layers of documentation, such as InCode Documentation, API Documentation, Architectural Documentation, and PR documentation, each aimed at enhancing different facets of the development workflow. By managing the comprehensive documentation process, Penify addresses the prevalent issue of documentation lagging behind code changes as software evolves. As a result, developers can focus more on coding while ensuring that their documentation remains relevant and up-to-date.
