What is Markdown

Markdown is a lightweight markup language created by John Gruber in 2004. It allows you to write formatted text using a simple, readable syntax: # for headings, ** for bold, * for italic, - for lists, and [text](url) for links. It is the standard format on GitHub, Stack Overflow, Reddit, Discord, and many more platforms.

Our Editor Features

Live preview that updates as you type, full GFM table support with column alignment, code blocks with syntax highlighting for over 100 languages, task lists with checkboxes, and export to clean, semantic HTML with a single click.

Use Cases

Ideal for writing technical documentation, GitHub READMEs, blog posts, class notes, formatted emails, and any content that needs structure without the complexity of a word processor. Copy the generated HTML directly into your CMS or publishing system.
