Write Markdown and see it rendered in real time. Pure client-side.
Markdown is a lightweight markup language for READMEs, docs, and many CMSs. A live preview shows headings, lists, code blocks, and links as you type.
Flavors differ (GitHub Flavored Markdown, CommonMark). Preview here is a practical browser rendering—verify on your target platform for extensions like tables or task lists.
Some renderers allow raw HTML; others sanitize it. Check your publisher’s rules.
