Pro Markdown Viewer for Mac

Pro Markdown Viewer icon

Coming soon to the Mac App Store

Free. No account, no subscription, no telemetry. macOS 11 (Big Sur) or later.

Pro Markdown Viewer is a fast, native macOS reader that turns any markdown file into a clean, readable document. Double-click a .md file and read it the way it was meant to look: real typography, a table of contents sidebar, images, tables, footnotes, working links, and Mermaid diagrams rendered inline. It's a reader, not an editor: keep writing in VS Code, vim, Cursor, or TextEdit, save, and the rendered view updates in place.


A markdown checklist with inline validation banners flagging a broken link

Validation that reads with you: broken links and malformed structure get inline banners next to the block they belong to

A Claude agent definition with its frontmatter card and the Explain panel open

Knows what an agent, a skill, or a CLAUDE.md is: frontmatter becomes a card, and every field is one click from a plain-English explanation

The AI Library window showing annotated configuration examples

54 annotated AI examples across Claude, ChatGPT, Cursor, Gemini, and Copilot: search, filter, and save any one as a clean starter

Two markdown documents open as native macOS tabs in one window

A Mac app through and through: native tabs, Quick Look from Finder, find inside the rendered document, print


Private by design

No account, no analytics, no telemetry. The renderer is bundled into the app, so displaying a file makes zero network requests and everything works offline. The whole policy fits on one page: read the Pro Markdown Viewer privacy policy.

More from Alec

If you present from your Mac, Pro Mouse highlights where you point and Pro Stage keeps you on screen. And KeyPeek shows every keyboard shortcut of the app you're in.
