About Markdown Editor

Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple, intuitive syntax — # for headings, **bold**, *italic*, [links](url) — that is easy to read as plain text and can be converted to HTML for rendering. It's the standard for README files, technical documentation, and blog posts across platforms like GitHub, Notion, and Slack.

Despite its simplicity, Markdown covers a wide range of formatting needs: headings (#), bold (**), italic (*), inline code (`), fenced code blocks (```), unordered lists (-), ordered lists (1.), blockquotes (>), links ([]), images (!()) and horizontal rules (---). Various flavors exist — CommonMark, GFM (GitHub Flavored Markdown), and others — each with slightly different feature sets.

This tool provides a split-view editor: write Markdown on the left and see the rendered HTML preview on the right in real time. You can also copy the raw Markdown source or the rendered HTML for use in other applications. A sample document is preloaded to help you explore the syntax.
