Markdown is a lightweight markup language for writing formatted text using plain characters: # for headings, * for emphasis, and backticks for code. It is the standard for README files, documentation, and many note-taking and chat tools.
This editor renders GitHub Flavored Markdown as you type, including tables, task lists, and fenced code blocks, so you can check how a README or document will look before you publish it. Rendering happens in your browser and the text is not uploaded.
Common use cases
- Previewing a README before committing it.
- Drafting documentation or release notes with live feedback.
- Checking that a table or task list renders correctly.
- Learning Markdown syntax by seeing the result immediately.

- Will it look identical on every platform?

- Can I use raw HTML?
- Support for raw HTML varies by renderer and is often restricted for security reasons.
