What is mMDd?

mMDd is a clean, light, and free Markdown editor for macOS and Windows. It started as a simple viewer and grew into a minimal but capable editor — no bloat, no subscription.

Features:

  • Obsidian-style tabs with drag-to-reorder, keyboard shortcuts (?1–9), and a right-click menu (Reveal in Finder, Duplicate, Close Others, etc.)
  • GFM rendering with syntax-highlighted code blocks
  • Split view (editor + live preview) with a draggable divider
  • Collapsible outline sidebar for quick navigation in long documents
  • Find (?F) and Find & Replace (??F)
  • Opens via drag-drop or file association (.md, .markdown, .mdown, .mkd)
  • Built-in help and keyboard shortcut guide

mMDd is free to use, with an optional one-time Pro unlock (5 themes + 6 fonts) for readers who want to customize their writing environment. The default Newsprint theme — warm cream paper, vintage red accents, Times serif — is the app's signature look.
