What is Markdown
Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple plain text syntax (like `# Heading`, `**bold**`, `- list`) to format documents, which can then be converted to HTML. Markdown has become the de facto standard for technical documentation, README files, blog posts, and notes, supported by GitHub, Stack Overflow, Notion, and many other platforms.
Markdown vs rich text editors
Markdown's biggest advantage is separating content from presentation — you focus on the content itself, with formatting controlled through simple markers. Compared to Word or Google Docs, Markdown files are plain text: smaller, version-control friendly, cross-platform consistent, and easy to process programmatically. The tradeoff is no complex layout support.
FAQ
- What Markdown syntax is supported?
- Standard Markdown and GitHub Flavored Markdown (GFM) are supported, including headings, bold, italic, strikethrough, links, images, code blocks, tables, task lists, blockquotes, and more.
- Is my content uploaded?
- No. All editing and rendering happens entirely in your browser using the marked library. Data is never uploaded to any server. Works offline.
- How do I export documents?
- Two export formats: Markdown (.md) preserves the source, HTML (.html) exports the rendered webpage. Use the download buttons in the toolbar. You can also copy Markdown source or HTML code separately.
- Why does preview styling differ from my website?
- The preview uses built-in styles that may not match your target site's CSS exactly. Export as HTML and view in your target environment for accurate results.
