Marked QL renders beautiful Markdown previews in macOS Quick Look. Powered by Apex for math, Mermaid, syntax highlighting, and more. $4.99 on the Mac App Store.







Congrats on the launch! Native Markdown previews in Finder are one of those features that seem small until you use them every day. I like the focus on integrating with the existing macOS workflow instead of creating another standalone app.
Does it support GitHub Flavored Markdown features like Mermaid diagrams, task lists, and tables?
Marked 3 - Markdown Preview for Mac
@dasmat13 Yep.
The fact that Quick Look previews handle Mermaid diagrams and math rendering natively feels like exactly the kind of detail macOS has been missing for years. Worth every penny just to finally preview READMEs without opening the whole editor.
I've been looking for a reliable Markdown Quick Look extension for a long time, and this is exactly what I needed. The previews are fast, clean, and accurate, with excellent support for syntax highlighting, Mermaid, and MathJax. Highly recommended for anyone working with Markdown on macOS.
this is one of those tiny utilities that should honestly already exist in macOS. the built in quick look for markdown just shows raw text with the hashes and asterisks still in it, which is annoying every single time. does it handle mermaid diagrams or code blocks with syntax highlighting, or is it focused on plain prose formatting for now
the part that's kept me from relying on Quick Look plugins in the past isn't feature coverage, it's macOS itself - Apple's had a history of Quick Look extensions silently stopping working after a system update until you manually re-enable them in Settings. has that been solid for you across recent macOS versions, or is that still a "check it after every update" kind of thing
A couple of years ago I was looking for something like this. I am a Marked user, and Brett suggested Peek. Marked QL is better. Way to go, Brett! The support page for fixing conflicts with other apps is a model for how support pages should be written.
Quarto support is coming soon, so I am a happy camper
