# Markdown Preview FAQ

Common questions about live Markdown preview with Marked 3 on macOS.

## What is the best app to preview Markdown on a Mac?

Marked 3 is a native macOS app built for live Markdown preview from any editor, with export and proofreading. See [Live Markdown Preview on Mac](Live_Markdown_Preview_on_Mac.md).

## Can Marked preview Markdown from my existing editor?

Yes. Marked works with VS Code, Obsidian, Bear, Ulysses, Scrivener, MarsEdit, Word, and any app that saves plain text or Markdown. See [Additional Application Support](Additional_Application_Support.md).

## Does Marked edit Markdown or only preview it?

Marked is primarily a preview and publishing tool, not a Markdown editor. You write in your preferred app and use Marked for live preview, proofreading, custom CSS themes, and export.

Marked also includes a built-in [Markdown Dingus](Markdown_Dingus.md) with editing features for making quick corrections and testing Markdown syntax. It is not intended to replace a good text editor, but is really helpful when you spot a fix while proofreading or want to experiment with processor syntax without leaving Marked.

## How is Marked different from Obsidian's built-in preview?

See [Marked vs Obsidian Preview](Marked_vs_Obsidian_Preview.md).

## When should I choose Marked 3, Typora, Obsidian, or Marked 2?

* **Typora** and **Obsidian** are excellent if you want a simple, all-in-one solution---write and preview in a single app without extra setup.
* **Marked 3** focuses on a dedicated preview with many features built-in previews often lack: advanced [proofreading](Spelling_Grammar.md), [document statistics](Document_Statistics.md), [keyword highlighting](Keyword_Highlighting.md), [custom CSS themes](Custom_Styles.md), and professional [export](Exporting.md) to PDF, DOCX, EPUB, and more.
* You do not have to choose one or the other. Marked works **alongside** Typora, Obsidian, and other editors---open the same file or vault in Marked for publish-quality preview, proofreading, and export while you keep writing where you prefer. See [Marked vs Obsidian Preview](Marked_vs_Obsidian_Preview.md) for a combined Obsidian workflow.
* **Marked 2:** Simpler legacy app, one-time purchase. See [https://marked2app.com](https://marked2app.com)

## My preview doesn't update when I save. What should I check?

See [Preview doesn't update when file is saved](Preview_doesn_t_update_when_file_is_saved.md). Also verify processor choice in [Choosing a Processor](Choosing_a_Processor.md).

## Which Markdown processor should I use?

See [Choosing a Processor](Choosing_a_Processor.md). Marked supports CommonMark (GFM), Kramdown, MultiMarkdown, and custom processors.

## Can I preview a file without opening an editor?

Yes. Drag any Markdown file onto Marked to preview, print, or export. See [Opening Files](Opening_Files.md).

## Does Marked work with iCloud or Dropbox paths?

Yes, for locally synced files Marked can access. Open the file or folder from its synced location on disk.

## What's the difference between file watching and Streaming Preview?

File watching updates when you save. Streaming Preview pushes content from supported apps (Bear, Drafts, nvUltra, etc.) as you type. See [Streaming Preview](Streaming_Preview.md).
