Marked Quick Look is a macOS Quick Look extension that renders Markdown files as formatted previews directly in Finder.
What is Marked Quick Look?
Marked Quick Look is a Mac productivity app and Quick Look extension for previewing Markdown files in Finder. It lets you select a Markdown document and press the Space bar to see a rendered preview instead of plain text, which is useful for writers, developers, and anyone who works with README files, notes, or documentation. The app supports Markdown preview workflows on macOS without requiring the full Marked app, while also integrating with Marked when it is installed. Its preview engine is designed to handle multiple Markdown styles and can display elements such as syntax highlighting, math, diagrams, and document structure. For users who manage text-heavy projects, it provides a faster way to inspect Markdown content before opening it in an editor.

Safety overview
Status: Safe
This is a legitimate macOS utility for viewing Markdown previews through Quick Look. It primarily needs access to the files you choose to preview, which is normal for its purpose. Removing it will stop enhanced Markdown previews in Finder, but it should not affect your original documents. As with any file-preview tool, use normal caution when opening untrusted files that may contain unexpected content.
Recommendation: Keep Marked Quick Look if you regularly preview Markdown files in Finder or want a quicker way to inspect documentation and notes. If you do not use Markdown previews, you can remove it without harming your documents; the main effect is that Finder will no longer show its enhanced rendered previews.
