The Markdown Editor lets you write Markdown and see a live, rendered preview side by side. Type in the editor on the left and the formatted result appears instantly on the right, so you always know exactly how your document will look.
It supports GitHub-Flavored Markdown (GFM) — headings, bold and italic text, links, images, lists, task lists with checkboxes, tables, blockquotes, and fenced code blocks with syntax highlighting. When you are done you can copy the Markdown or the rendered HTML, or download a .md or .html file. Everything runs in your browser and your text is auto-saved locally, so nothing is ever uploaded.
How to use the Markdown editor
- Type or paste Markdown into the editor pane on the left.
- Use the formatting toolbar (or shortcuts like Ctrl/Cmd + B for bold and Ctrl/Cmd + I for italic) to insert Markdown syntax.
- Watch the live preview on the right update as you type. Switch between Editor, Split, and Preview views any time.
- Copy the Markdown or HTML, or download a .md or .html file. Your work is saved automatically in this browser.

What is Markdown?
Markdown is a lightweight, plain-text formatting syntax created by John Gruber. It lets you add structure — headings, lists, links, emphasis — using simple characters, without writing HTML. Because it is just text, Markdown is portable, version-control friendly, and readable even before it is rendered.
It is the standard for README files on GitHub, documentation, static-site and blog content, notes apps, chat tools, and forums. GitHub-Flavored Markdown (GFM) adds practical extras such as tables, task lists, and strikethrough, all of which this editor supports.
