Markdown Studio — Offline WYSIWYG Markdown Editor

Markdown Studio

A distraction-free Markdown writing desk with three ways to work — and zero accounts.

Write README files, docs, developer notes or articles using whichever workflow you like:

• WYSIWYG Editor — select, type and format in a familiar rich-text writing canvas.

• Markdown Mode — edit raw Markdown with a simple formatting toolbar.

• Split View — type Markdown next to a live, read-only preview.

Features

• Headings and a navigable document outline

• Bold, italic, strikethrough, links, inline code and blockquotes

• Bullet and numbered lists, fenced code blocks and tables

• Open .md / .markdown / .txt files (up to 2 MiB)

• Save Markdown and export standalone HTML

• Word count, character count and approximate reading time

• Local browser autosave where permitted

• Responsive layout for desktop and mobile

Private by design

Your text stays on your device. No sign-up, external libraries, server uploads, analytics or tracking. The app works offline after opening the file. External links in your own documents can open only if you click them.

Note: Markdown Studio supports a practical subset of Markdown. Some advanced Markdown features (e.g. images, task lists, extensions and arbitrary raw HTML) are intentionally not rendered in this initial version. Round-tripping through the visual editor can normalize spacing and Markdown syntax. Save a source backup when editing complex documents.

Tips: Click Run tool, then select WYSIWYG for visual editing, Split to preview Markdown source, or Markdown for precise editing. Use Save .md and Export HTML at the top.
