A live Markdown editor: type on the left and see the rendered result instantly on the right. The built-in mini renderer supports # to ###### headings, **bold**, *italic*, `inline code`, fenced ``` code blocks, [links](url), unordered and ordered lists, > blockquotes, horizontal rules and paragraphs.
The whole input is HTML-escaped first and only then transformed by the Markdown rules, and link URLs are restricted to http, https, mailto and relative targets — so pasted content cannot inject scripts. Everything runs locally in your browser, nothing is uploaded.
