Margo: Markdown Editor

A native Markdown editor for Mac, iPad, and iPhone. Built entirely in SwiftUI — not a web app in disguise.

YOUR FILES, NOT OUR VAULT Margo opens .md files from your filesystem. No proprietary database, no locked-in library, no special folder structure required. Your files stay yours, readable by any app, synced by any service. Edit a file in Margo, open it in another editor — it just works.

ONE APP, EVERY APPLE DEVICE The same full-featured editor on Mac, iPad, and iPhone. Not a desktop app with a stripped-down mobile companion — real feature parity across every screen. One purchase covers all your Apple devices.

LIVE PREVIEW WITH BIDIRECTIONAL SCROLL SYNC See your Markdown rendered in real time. Scroll the editor and the preview follows. Scroll the preview and the editor follows. Both directions, always in sync.

MATH, DIAGRAMS, AND 30+ LANGUAGES — OFFLINE LaTeX equations via MathJax. Flowcharts and sequence diagrams via Mermaid. Syntax highlighting for 30+ programming languages via Prism. Everything is bundled inside the app. No internet connection needed, no external CDN, no tracking.

EXPORT TO WORD, PDF, EPUB AND MORE Turn any document into a Word file (.docx), an EPUB ebook, RTF, a styled HTML page, or a print-ready PDF — right from the toolbar. Word export keeps real heading styles, so your outline and table of contents carry over to Word, Pages, and Google Docs.

MAKE IT YOURS 11 preview themes and 15 editor themes. Adjust font size, tab width, tabs or spaces — every preference is live-applied, no restart needed.
