Markdown Editor / Preview

The Markdown Editor and Preview lets you write in Markdown on the left and watch it render to HTML on the right in real time.

It covers the everyday subset you actually use: headings, bold and italic, inline code, fenced code blocks, ordered and unordered lists, blockquotes, horizontal rules, links and images.

Flip the right pane between a styled visual preview and the raw HTML source, then copy that HTML with a single click to paste into a CMS, an email template, a README or a static site.

Safety is built in.

Every piece of your text is HTML-escaped before any Markdown formatting is applied, so a stray angle bracket or an embedded script tag is rendered as literal text rather than executed.

There is no raw-HTML passthrough, which means the preview cannot run arbitrary markup — useful when you are pasting content from an untrusted source.

A small status bar keeps a live count of words, characters and lines as you type.

It is handy for drafting documentation, writing release notes, composing forum or GitHub posts, and learning Markdown syntax by seeing instant results.

Everything runs locally in your browser — your draft is never uploaded, logged or stored — so it is safe for private notes and keeps working offline once the page has loaded.
