A free, notarized Mac app that only reads Markdown: no editor, no account, nothing to configure. It renders tables, footnotes, task lists and Mermaid diagrams offline, reloads when the file changes on disk, follows links between .md files with back and forward, and shows embedded HTML as plain text rather than running it. Made for the reports coding agents leave behind; Apple silicon, macOS 14 or later, MIT-licensed.
