What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It lets you write plain text with simple formatting symbols that convert to well-structured HTML. The philosophy is that a Markdown document should be readable as-is, even without rendering.
GitHub Flavored Markdown (GFM) extends the original spec with tables, task lists, strikethrough, and fenced code blocks with syntax highlighting — making it the de facto standard for developer documentation, READMEs, and wikis.

Frequently Asked Questions
Is this editor saved anywhere?
No. This is a fully client-side tool — your text never leaves your browser. There is no server, no account, and no storage. Refresh the page and the content is gone.
What Markdown flavors are supported?
This editor supports CommonMark syntax plus key GitHub Flavored Markdown (GFM) extensions: tables, strikethrough (
~~text~~), and fenced code blocks with language labels.How do I create a table?
Use pipe characters and dashes:
| Col1 | Col2 | then | --- | --- | on the next line, followed by data rows. Alignment is supported with :---: (center) or ---: (right).Can I export the rendered HTML?
Yes — click Copy HTML in the toolbar to copy the full rendered HTML to your clipboard. You can paste it directly into a CMS, email template, or HTML file.
What is the difference between Markdown and HTML?
HTML is the final markup that browsers render. Markdown is a human-friendly shorthand that compiles to HTML. Markdown is faster to write and much more readable as raw text, while HTML gives you full control over structure and styling.
