  3. 3Fix issues the lint panel flags (broken heading jumps, unclosed fences, list depth).
  4. 4Copy the markdown, or send it to the HTML / plain-text / TOC tools with the export buttons.

Markdown Live Editor FAQ

Which markdown flavor does the editor support?
The CommonMark essentials writers actually use: ATX headings (#–######), emphasis and strong, inline code, fenced and indented code blocks, blockquotes, ordered/unordered/task lists, tables, thematic breaks, autolinks, and images. The renderer is deterministic — the same markdown always renders the identical HTML.
Is my writing uploaded anywhere?
No. Rendering runs entirely in your browser under a strict Content-Security-Policy that blocks all network connections — your draft never leaves your device. There is no account and no server-side save.
Can I keep working offline?
Yes. The site is an installable PWA with an offline service worker — once loaded, the editor works with no connection at all.
Can I export what I write?
Yes — copy the rendered HTML or download it as a standalone styled .html file from the HTML Export tool; the same source converts to plain text or a table of contents with one click.
