Frequently Asked Questions

What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It lets you format text using simple syntax - like **bold**, *italic*, # headings, and [links](url) - that gets converted to HTML. It's used everywhere: GitHub READMEs, documentation sites, blogs, forums (Reddit, Stack Overflow), and note-taking apps like Obsidian and Notion.
Does the preview update in real-time?
Yes. As you type in the editor pane, the HTML preview pane updates instantly. There's no delay or 'render' button - every keystroke triggers a re-render so you always see exactly what your Markdown looks like.
Can I copy the rendered HTML?
Yes. Click the 'Copy HTML' button to copy the rendered HTML source code to your clipboard. This is useful if you need to paste formatted HTML into a CMS, email, or website editor that accepts HTML.
What Markdown syntax is supported?
This editor supports standard Markdown (CommonMark) including headings, bold, italic, strikethrough, links, images, code blocks (fenced and indented), blockquotes, ordered and unordered lists, horizontal rules, and tables. It uses the 'marked' library which is one of the most popular and well-tested Markdown parsers.
Is my text stored or sent anywhere?
No. Everything runs 100% in your browser. Your Markdown text is never uploaded, stored, or transmitted to any server. You can safely use this editor for private notes, confidential documentation, or any sensitive content.
