MacMD Viewer: a read-only Markdown viewer for reviewing what Claude writes
MacMD Viewer is a native, read-only Markdown viewer for macOS. Press space in Finder for a formatted Quick Look preview, or open a window with an outline, syntax highlighting, Mermaid diagrams and auto-reload. Being read-only is the point: you can read SKILL.md and REFERENCE.md files while Claude edits them, without an editor fighting over the file. $19.99, or included with Setapp.
