A fast, focused Markdown editor
Marker is a Markdown editor and previewer for iPhone, iPad and Mac. Open any Markdown file, edit it in a clean monospaced editor, and see exactly how it will look in a live rendered preview. No accounts, no clutter, just your words.
Write without memorising syntax
A built-in formatting toolbar inserts the Markdown for you. Select some text and tap to apply:
- Bold, italic and strikethrough
- Inline code and fenced code blocks
- Headings 1 to 6
- Bulleted and numbered lists
- Blockquotes
- Links and images
- Tables
- Horizontal rules
Nothing selected? Marker inserts a placeholder and highlights it, so you can type straight over it.
See the result instantly
- iPad and Mac. The editor and preview sit side by side and update as you type
- iPhone. Switch between editing and preview with a single tap
- Links. Links in the preview open when you tap or click them
Find what you need
Search your text in the editor, or search the rendered preview to jump to the part of a document you are reading.
