Marked 2
Marked 2 is a macOS Markdown preview and writing companion that renders plain-text documents live while you edit them in your preferred text editor.
What is Marked 2?
Marked 2 is a native macOS writing companion for previewing Markdown and other text markup files as formatted documents while you work in your preferred editor. It is designed for writers, developers, and note-takers who want a live rendered view without changing their existing editing workflow. The app can open Markdown, HTML, and OPML content, refresh previews when files are saved, and help you review structure, readability, and presentation before publishing or exporting. It also includes document navigation tools such as search, bookmarks, and a table of contents, plus proofing and reading statistics that help with editing longer documents. Marked 2 supports export to formats such as HTML, Rich Text, PDF, and OPML, making it useful for drafting, reviewing, and sharing polished output. Brett Terpstra publishes it as a focused desktop app for Mac users who write in plain text.

Safety overview
Status: Safe
Marked 2 is a legitimate Mac writing utility. It normally needs access to the files you choose to preview and export, which is expected for a document-preview app. If you use advanced workflows such as custom processors or external tools, review what those tools do before enabling them, because they can affect how your documents are processed.
Recommendation: Keep Marked 2 if you use Markdown or other plain-text writing workflows on your Mac. Remove it only if you no longer use its live preview, proofing, or export features, since deleting it will mainly affect your writing and review workflow rather than your documents themselves.
