►http://markedapp.com
Marked opens #MultiMarkdown, #Markdown, #Text or #HTML files and previews them as HTML documents. It watches the file for changes, updating the preview any time the file is saved. With a full set of preview styles, Marked adds an ideal “live” Markdown preview to any text editor.
