# MuM

> Read, search, and render Markdown projects in a native Mac app.

MuM is a native Markdown reader for Mac that keeps several projects open with quick switching between them. It remembers reading positions and provides file search, full-text project search, document outlines, and navigation history. Opening a single file hides the project sidebars for a simpler reading view.

The app can export a document as a long PNG or paginated PDF, including page-break hints from the source. Its command-line tools expose the same rendering engine and return structured results for outlines, searches, and checks, making them useful to coding agents as well as people. MuM is open source and also reads several common document and data formats.
