Everything a Markdown draft needs. Nothing it doesn't.

Instant preview

Rendering runs in a Web Worker, so even long documents do not freeze the editor.

GitHub Flavored Markdown

Tables, task lists, strikethrough, autolinks and raw HTML — the way GitHub shows them.

Many drafts, one place

A file sidebar, an outline of headings and a resizable split. Open and download real .md files.

Clean HTML in one click

Copy Markdown or sanitized HTML, ready to paste into a CMS, an email or a docs page.

Print and PDF

The preview prints cleanly: use the browser's Save as PDF to share a finished page.

Hard to lose work

Autosave, a conflict warning when two tabs edit one draft, and recovery of unsaved edits after a reload.

Your words never leave this browser.

You type

CodeMirror edits the source. The page is static files, with no backend to send anything to.

A worker renders

unified and remark turn Markdown into HTML in a background thread.

DOMPurify cleans

Scripts, event handlers, frames, forms and unsafe links are removed before anything is shown.

IndexedDB keeps

Drafts and preferences are saved locally on this device. No analytics, no telemetry.

Local means local: drafts live only in the browser and on the address where you wrote them. Clearing site data deletes them, so download important files as .md.
