Introducing Marked QL — Markdown preview in Finder

I’ve been working on something small but useful, and it’s out now: Marked QL , a Quick Look extension that renders Markdown previews right in Finder. Select a .md file, hit Spacebar, and you get a real preview — not plain text, not a sad monospace dump, but actual formatted output with math, diagrams, syntax highlighting, the works. It’s a companion to Marked, but it doesn’t require Marked. If you do use Marked 3 , you’ll get shared preview preferences and an Open in Marked button when you want the full app
