Write once and preview the result
Markdown uses plain-text markers for headings, lists, links, and emphasis. The editor renders a live preview so you can check structure before copying or exporting the result.
A preview is not guaranteed to match every publishing platform. GitHub, a blog engine, and a documentation site can apply different Markdown extensions and styles; check the final destination too.
Preview safety and privacy
The preview removes raw scripts, event handlers, and dangerous links from rendered HTML. Even so, review any content copied from an untrusted source before publishing it elsewhere.
Editing and previewing run locally in the browser. Save your draft outside the page if you need a durable copy; closing a tab is not a backup method.
