.md Viewer

Read and edit the Markdown your AI agents write — without leaving the browser.
A Markdown, HTML, and PDF viewer & editor that runs on Mac, Windows, and the web.

The text you're reading right now is a .md template, rendered live by your
browser. Hit "✎ Edit" in the top right and you can rewrite it on the spot.

What it does

  • Read — preview Markdown, HTML, and PDF beautifully, in the browser or the native app
  • Write (browser) — edit Markdown inline. Save through the native app
  • Write (app) — multi-tab editing, multi-folder watching, PDF / HTML export, auto-reload on external changes
  • AI-friendly — handle .md from Claude, Codex, Cursor, Aider, and other agents in a way non-engineers can actually use

When to reach for it

Situation Approach
Read ChatGPT output cleanly Paste here and edit
Polish .md an AI generated Edit, then save to a local file (app)
Run several AI agents in parallel Watch multiple folders (Pro)
Skim a PDF report Browser or app, either works

Why it exists

"Anyone, not just engineers, should be able to read AI-generated Markdown as a clean
document." We wanted that — without the weight of Notion or Confluence, and with the
lightness of opening a local .md instantly.

Built with Tauri as a native app (Universal binary for Mac and Windows) plus a browser
version. Files never leave your machine — everything is processed 100% locally.
