#A fast Markdown viewer for Mac

You have folders full of Markdown — notes, READMEs, documentation, AI chat exports — and macOS gives you two bad options: Quick Look's bare-bones text preview, or opening a heavyweight editor just to read a file.

MD Flow is the third option: a native Mac app that treats Markdown like what it is — files — and renders them beautifully the moment you click.

#Browse folders, preview instantly

Connect any folder — a project repo, your documentation tree, an iCloud folder, an Obsidian vault. MD Flow shows a clean, native file browser next to a live preview pane:

• Click a file, see it rendered instantly — no open/close cycle
• Syntax-highlighted code blocks, tables, task lists
• Mermaid diagrams rendered inline — flowcharts, sequence diagrams, Gantt charts
• KaTeX math, callout blocks, and YAML frontmatter shown as a tidy header
• Table of contents for long documents, find-in-document, folder search

#Native, not another Electron app

MD Flow is built with SwiftUI. It launches fast, feels like a Mac app, and stays light. There is no indexing step, no database, no workspace concept — it reads your folders directly, so it works with the structure you already have.

#Private by default

Your files never leave your Mac. No account, no cloud processing, no lock-in. What MD Flow reads stays on your machine.

#Made for the AI-files era

If you save Claude or ChatGPT outputs, generated research, or project docs as .md files, MD Flow is the reading layer for that growing archive: browse it, search it, reopen recent files, and export any document as a polished PDF with MD Flow Pro.

MD Flow is free on the App Store, with a one-time Pro unlock — no subscription. It also runs on iPhone and iPad with the same purchase — see Markdown on iPhone and iPad.
