A Free Markdown Editor for Mac: Meet Markdown Writer
Markdown Writer started as a markdown editor that lives in a browser tab. Today it is also a native markdown editor for Mac: a small, fast app with the same live preview, the same rendering, and your documents stored on your own machine.
Download Markdown Writer for Mac — free, about 6 MB, requires macOS 26 or later.
If you would rather not install anything, the web editor is still one click away and always will be.
Why build a Mac markdown editor at all?
The browser version covers most days. But a few things only a real Mac app can do well:
- It is there when the network is not. Documents live on your Mac, so the app opens instantly on a plane, in a tunnel, or when the Wi-Fi is having a day. It is an offline markdown editor first and a synced one second.
- It behaves like a Mac app. A real menu bar, standard shortcuts, a proper Settings window, native text editing, and light and dark appearances that follow the system.
- It is one keystroke away. Press
⌃⌥Nfrom any app and you are typing in a new document.⌃⌥Mshows or hides the window. Both shortcuts are yours to change. - No Electron. The app is written in Swift with SwiftUI and AppKit. It launches quickly and the download is smaller than most web pages’ hero images.
What you get
Live preview, three ways
Write on the left and watch it render on the right, or switch to editor-only when you want a distraction-free writing app, or preview-only when you just need a markdown viewer on your Mac. The preview uses the same renderer as the website, so what you see is what you will publish.
GitHub-flavored markdown and the extras
Tables, task lists, strikethrough, and autolinks all work. On top of that:
- Syntax highlighting for code blocks
- KaTeX math, inline and block
- Mermaid diagrams rendered in place
[[wiki links]]between your documents, with suggestions as you type
New to the syntax? The markdown cheatsheet covers all of it on one page.
Collections that nest
Group documents into collections, and nest collections inside each other by dragging them in the sidebar. A command palette (⌘K) jumps to any document or command with fuzzy search, so large libraries stay quick to navigate.
Bring your existing .md files
Wondering how to open an .md file on a Mac without it showing up as raw text? Drag the file into the Markdown Writer window. It is imported as a document and rendered immediately.
When you need your writing somewhere else, export any document as Markdown or as a standalone HTML file. For a PDF, the web app’s markdown to PDF converter produces print-ready output.
Publish with a link
Sign in, press ⇧⌘P, and your document becomes a clean, shareable web page. Update or unpublish it whenever you like.
Sync and AI, if you want them
The Mac app is free. A Pro account adds:
- Sync between the Mac app and the web editor, so a draft started on one is waiting on the other
- An AI writing assistant (
⌘J) that drafts from a prompt or refines the passage you have selected, with the change shown inline before you accept it - Image uploads: drop an image into the editor and it is uploaded, linked, and kept in a library you can reuse across documents
None of it is required. Without an account the app is a complete, local markdown editor.
Private by default
Your documents are stored in the app’s sandboxed container on your Mac. Nothing leaves the device unless you sign in to sync or choose to publish. The app is signed and notarized by Apple, and it updates itself in the background, so you stay current without visiting a download page again.
How it compares
People looking for the best markdown editor for Mac usually end up choosing between a few familiar names. Here is where Markdown Writer sits:
| Markdown Writer | Typical alternatives | |
|---|---|---|
| Price | Free, optional Pro | Often a paid license or subscription |
| Built with | Native Swift | Frequently Electron |
| Live preview | Split, editor-only, or preview-only | Varies |
| Math and diagrams | KaTeX and Mermaid built in | Often plugins, or missing |
| Works offline | Yes | Usually |
| Web version | Yes, same documents with Pro sync | Rare |
| Publish to a link | Built in | Rare |
If you have been searching for a Typora alternative or a MacDown alternative that is still actively developed, it is worth ten minutes of your time.
