HOW IT WORKS
Open a file.
Follow the document.
Follow links. Find your way back.
Follow links between your documents, then go back to where you left off. Move to the next or previous document without leaving the window.
See how relative links workKeep the headings in view.
A readable page at the center. Your files to one side, the heading outline to the other. Everything in its place.

The file changes.
You stay on the page.
Read a plan, report, or README while your coding agent works. When the open file changes on disk, Aero Markdown reloads it and keeps your place. If you have unsaved edits, they stay intact until you choose to reload.

An optional local setup command lets Claude Code, Cursor, and Windsurf open the Markdown they write in the existing window, in the background. Codex is not included in these hooks. Aero Markdown has no AI chat or model calls.

What is Aero Markdown?
Aero Markdown is a native macOS Markdown reader for files already on your Mac. Open a file or a folder and read with a file tree, rendered page, and heading outline. It requires macOS 14 or later.
Does Aero Markdown need an account or a cloud library?
No. There is no account or cloud library. Files stay on your Mac, the app works offline, and nothing in a document is sent to a service.
How do links and navigation work?
Relative links between Markdown files inside the opened folder open in the app. Back and forward remember your place. You can also move to the next or previous document and copy a relative link to the current heading.
Is Aero Markdown available to download?
Not yet. Aero Markdown is $14.99 USD, one-time, for a lifetime Aero 1.x license for one Mac. Download and checkout are not available yet. Meanwhile, you can read a Markdown file in the free online reader.
Your files are already there.
