What Is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It allows you to format text using simple characters: # for headings, ** for bold, * for italic, - for lists, and > for blockquotes. Markdown is widely used for README files, documentation, blog posts, forum comments, and note-taking. It is supported by GitHub, GitLab, Reddit, Stack Overflow, Notion, and many other platforms.
Supported Syntax
This editor supports standard Markdown syntax including headings (H1–H6), bold and italic text, ordered and unordered lists, blockquotes, inline code and code blocks, horizontal rules, links, images, and tables. The preview updates instantly as you type with no delay.
