Additional Application Support

In addition to support for Scrivener, Marked also provides tools for working with other applications which aren’t normally accessible as text files.


To enable iThoughtsX preview, you must set “Markdown Preview” in the iThoughts preferences (under Advanced). Choose All topics to show the full map, and “Visible topics” to only preview currently-expanded branches.

In Marked, you can then open an iThoughtsX (itmz) file directly, and it will be previewed as a document outline. Optionally, enable Outline Mode in the Gear menu to show it as an APA or Decimal outline.

Changes from iThoughtsX are reflected on Save.


Drag a MindNode map onto the Marked icon and the preview will show your map in Marked, mimicking the Markdown export option in MindNode.


Drop a VoodooPad document onto Marked and it will preview the page that’s open in VoodooPad whenever you’re editing. Hit ⌘S to get an accurate preview with full MultiMarkdown rendering, all in your favorite styles.

If you reference images located within in your VoodooPad document using HTML or Markdown syntax, Marked will detect and load them from within your VoodooPad file. The preview will match what VoodooPad will export.


In the Preview menu in the menubar you’ll see an option to launch the MarsEdit Preview. MarsEdit doesn’t store files on the disk, so you have to launch the special window. Once open, it will preview the post you’re editing in MarsEdit, keeping up with you as you change posts. You can save manually to update the preview, or let Marked watch for autosaves and update automatically.

If your post has content in the “extended content” portion of the MarsEdit editor, a WordPress-style <-- more --> tag will be inserted automatically in Marked’s preview and source views. This will provide pagination in WordPress and Jekyll blogs, and–because it’s an HTML comment–won’t affect output in other blogs.

While there’s currently nothing extra done with them, the tags and categories of your post are stored in MultiMarkdown metadata variables. If you’re using the MultiMarkdown processor (Marked 2 Preferences (⌘,), Processor pane), you can use metadata substitutions like this:

Tagged: [%tags]
Posted In: [%categories]

(I’ll admit I don’t know how that would be useful. I have plans to use the data for more constructive purposes in the future.)

Notational Velocity, nvALT, and any folder of text files

You can drag an entire folder to the Marked icon and it will open a window which always shows the most recently edited text file in the folder. Marked watches for changes in all files, then looks for the newest text file and displays it. If the file is the same as the last check, then it scrolls to the edit position and works as usual.

This works well with Notational Velocity-style applications, but is also great for working on multi-file documents when you only need to see the section you’re currently working on.

Ulysses III

You can preview the current document in Ulysses III using the send-to feature and selecting Marked as the target application. Live updates should begin once the document has been opened from Ulysses. Make sure the file type is set to Markdown (md), not HTML.

You can also have Ulysses generate an index file for an external source in the folder’s preferences. Opening this file in Marked will show the entire contents of the file group combined.

MultiMarkdown Composer

MultiMarkdown Composer offers the option to use Marked as the default preview. Check the Preview preferences or use ⌘⌥P to open your current document in Marked.

OmniOutliner / OPML

Most apps that can save as OPML can be used with Marked. Just drag the OPML file to Marked as you would any Markdown file.

Xcode Playground Files

Xcode playground files can include Markdown in comments. Open a .playground file in Marked and it will show your marked-up comments as HTML, and your code as highlighted code blocks.


Preview Bear notes in Marked by selecting View->Preview in Marked from within Bear.

Clipboard Preview

You can preview the contents of your clipboard as Markdown (or whatever default custom processor you have set) by selecting Clipboard Preview from the Preview menu, or by pressing ⌘⇧V.


Some application-specific settings can be found in Apps preferences.
