What MD Flow does, and why each piece matters.

#Browse folders in a file-first interface

Connect any folder on your Mac, iPhone, or iPad. MD Flow shows a clean, native file tree. Nothing to import, no database, no vault. More on how that works: browse a whole folder of Markdown files on Mac.

• Expand and collapse folders inline
• Drill into any folder to focus on its contents
• Filter to Supported files (Markdown) or show All

#Preview Markdown instantly

Click a file. Read it. That is the whole loop. What it renders, in detail: a fast Markdown viewer for Mac.

• Rendered Markdown with a clean reading typography
• Images inside your documents render in place; tap one to see it full screen and zoom in
• [[Wikilinks]] open the file they point to
• Edit in another app and the preview follows each save, without losing your place
• Auto-generated table of contents for long documents
• Recent files always one click away

#Stay local and private

Your files never leave your device unless you choose to share them.

• No account, no sign-in, no cloud sync requirement
• Works offline
• No telemetry tied to your content

#Cross-device by design

Same workflow on Mac, iPhone, and iPad. Native on each, not a single Electron shell repackaged three times. On the smaller screens: read Markdown on iPhone and iPad.

• macOS: keyboard-first navigation, native file-browser chrome, and a rendered Quick Look preview when you press Space on a Markdown file in Finder (how the spacebar preview works)
• iPad: two-pane layout with touch and pointer support
• iPhone: drill-in navigation optimized for one-handed reading

#Search that respects your files

Search file names for free. With Pro, search inside your documents too — matches show the line and its number. Everything is scoped to the folders you have connected, with no background indexer eating your battery.

#Built for Markdown-heavy workflows

• AI-generated exports from ChatGPT, Claude, and Cursor (and where to keep what your AI writes)
• Exported notes and wiki dumps
• Obsidian vaults, opened as they are: a lightweight reader for your Obsidian vault
• Technical documentation and specs
• Research folders, reading lists, and archives

#With MD Flow Pro

The free version is fully usable on its own. Pro is a one-time unlock for people who live in Markdown-heavy folders all day:

• Unlimited connected folders. Connect as many as you want.
• Higher volume of recent and loose files. Surface more of what you have been working on across all connected folders.
• Search inside your documents. Not just file names — find the line you wrote, with its number, across every connected folder.
• Email drafts, one tap from your mail app. Give a Markdown file a to: line in its frontmatter and MD Flow treats it as a draft — it opens prefilled in Mail, Gmail, or Outlook with the subject, recipients, and formatting intact. You press Send.
• Export polished PDFs. Math, diagrams, callouts, tables and images survive the page.
