A fast, local-first Markdown editor that lives in your browser.

  • Type on the left, see it render on the right
  • Works offline, installs as an app
  • Your notes stay on your device

NOTE

Try editing this — it's the real editor.

Editing your way

Side-by-side, or one pane at a time.

Write with a live preview beside you and synced scrolling, or switch a single pane between code and rendered view. Your cursor and scroll stay put when you flip.

Yours, and offline

No network required.

Your documents live in your browser, not on someone else's server. Full editing, local search, and export all work with no connection. Install it as an app on Mac, iPhone, Android, and Windows.

Real GitHub-flavored Markdown

Everything you'd expect — and the hard parts too.

Tables, task lists, and syntax-highlighted code, plus Mermaid diagrams, KaTeX math, footnotes, and GitHub alerts. One pipeline renders your preview and every export, so they never disagree.

What it renders

Tables, task lists, and code — exactly like GitHub.

Export anywhere

Take your writing with you.

Export a self-contained HTML file, a print-quality PDF, or a Word document — all generated on your device from the same rendered output.

Share a link

Send a read-only snapshot.

Create an unguessable link to a copy of a document. Recipients read it in the browser and can save it to their own library. Sharing is the one time content leaves your device — and only the document you choose.
