MacMD Viewer, the Markdown viewer for Mac that reads what your agent writes
MacMD Viewer is a read-only Markdown viewer for Mac: it renders .md files with Mermaid diagrams, highlighted code and a Finder preview on the space bar, and exports them to PDF. It costs $19.99 as a one-time purchase. I tested every feature on my Mac: it is comfortable to use and covers a wide range of uses.
