How it works
Markdown is the format of READMEs, documentation, issues and release notes. This tool lets you write it and see the result live, without opening a repository or installing an editor.
Type on the left and the preview updates as you go. GitHub Flavored Markdown is supported: headings, emphasis, lists, task lists, aligned tables, quotes, links and code blocks. At the top you see the word count and the estimated reading time.
Switch to HTML to see the code the Markdown produces, ready to paste into an email, a CMS or a template. Copy HTML copies it in one click.
The preview is safe: raw HTML is shown as text, javascript: links lose their target and external images are not downloaded. You can review someone else’s README or AI-generated text without anything running.
Everything happens in your browser: what you write is never stored, logged or sent to a server, so drafts with internal details stay private.

Frequently asked questions
Which Markdown flavor does it use?
GitHub Flavored Markdown (GFM), with tables, task lists, strikethrough, autolinks and fenced code blocks with a language. It is what READMEs, issues and most wikis use.
Why is the HTML I wrote not rendered?
For safety, HTML inside the Markdown is shown as text and javascript: links are disabled. Pasting a document from an unknown source runs nothing in your browser.
Why are images not loaded?
External images are replaced with their alt text: loading them would make a request to another server, and the tool never sends anything outside your browser. Embedded data: images are shown.
