Marked QL brings Markdown previews to Quick Look

Marked QL is a macOS Quick Look plugin developed by Brett Terpstra that renders rich Markdown previews directly in Finder via the spacebar. Powered by the Apex parser, it supports math, Mermaid diagrams, and code syntax highlighting for $4.99.

// ANALYSIS

While macOS users have long relied on free, hacky CLI workarounds or heavy editors to preview markdown files, Marked QL delivers a polished, native integration that is well worth its $4.99 price tag for any serious developer or technical writer.

–Native Integration: Seamlessly hooks into Finder's Quick Look spacebar shortcut, keeping workflows fast and lightweight.
–Feature-Rich Rendering: Built-in support for MathJax, Mermaid diagrams, and code syntax highlighting sets it far apart from basic text-based preview tools.
–Independent Utility: Functioning as a standalone tool, it does not require the full Marked 3 app to provide value.

While it provides significant cost savings by exploiting lower flat-rate pricing for visual tokens, this visual representation can lead to slower completion times and lower accuracy on byte-exact information like file paths and code snippets.
