A fast, native Markdown editor for your Mac — live preview, split view, full GitHub-flavored Markdown, dark mode, and no tracking. MarkNook is a fast, native Markdown viewer and editor for the Mac. Open any Markdown file, watch the live preview update while you type, and switch between editor, split view and preview with a click or a keyboard shortcut. LIVE PREVIEW The preview follows GitHub-flavored Markdown (GFM): headings, lists, tables, task lists, strikethrough, code blocks, links and images look exactly the way you expect. Links open in your browser, and the preview follows the system's light or dark appearance. A REAL MAC EDITOR The editor is a true native text view with undo, find and replace, optional spell checking and a crisp monospaced font. Smart quotes and automatic text replacement stay off, so your Markdown remains exactly what you typed.
