How to use the Markdown editor

  1. Type or paste Markdown on the left — or drop a .md file onto the editor — and watch the preview update as you type.
  2. Use the toolbar for bold, headings, links, code blocks, task lists and tables; each button wraps the text you have selected.
  3. Download the .md source, or export a standalone HTML file with the styling baked in that you can open or email as-is.

FAQ

Is my document saved anywhere?

Only in your own browser. The draft is kept in localStorage so it survives a reload or an accidental tab close, and it is never sent to a server. Use Reset to wipe it.

Which Markdown flavour is supported?

GitHub Flavored Markdown, rendered with marked 12: pipe tables, task lists, strikethrough, fenced code blocks with highlighting, and single line breaks kept as line breaks.

Is raw HTML allowed in the Markdown?

Inline HTML renders, but the result is passed through DOMPurify before it is shown, so scripts, event handlers and other unsafe markup are stripped from both the preview and the exported file.
