Community Voice & Feedback
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
The muscle memory is real: hit space, see nothing, sigh, wait for the file to open in Cursor just to check it's the right one. I do this ritual ten times a day) Never once has it stopped annoying me — and it took this launch to realize the fix could just... exist)
Interesting, but definitely not "$4.99 on the Mac App Store".
Quarto support is coming soon, so I am a happy camper
Congrats on the launch! Since Quick Look runs sandboxed, does it resolve relative image paths and links inside the markdown file correctly, or does that break outside of Marked 3's own preview?
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
Nice — Quick Look for markdown is one of those things macOS should have shipped with. Does it handle mermaid diagrams or just standard markdown?
That's nice. Does it handle YAML frontmatter in README files, or does it render those as plain text?
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.
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.
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?
@ttscoff Congrats on the launch of Marked QL, Brett! 🚀 Having native Markdown Quick Look back in macOS with modern rendering is huge.Quick question on customization: does Marked QL allow using custom CSS/themes for the Quick Look render (like custom syntax highlighting themes or dark/light mode sync), or does it default to standard system styles?
Very neat idea! Native previews always feel faster than opening another app.Curious...does it support large Markdown files without slowing down?Best of luck with the launch! 🚀
Hey Product Hunt,

Just a solid Quick Look preview for Markdown files, complete with syntax highlighting, Mermaid, MathJax, and more. Compatible with CommonMark, GFM, Multimarkdown, Kramdown, and all your favorite Markdown flavors (powered by Apex).
