A compact, fast Markdown viewer for Apple Silicon Macs running macOS 14 or later, built in Swift to provide a read-only experience with no editor, accounts, telemetry, or configuration. It renders standard Markdown features - headings, tables, code blocks, task lists, footnotes and local images - plus offline Mermaid diagrams, and supports .md, .markdown and .mdx (MDX shown as plain text). Navigation includes find (⌘F) with match highlighting and counts, keyboard search navigation, intra-repository Markdown links that open in the same window with back/forward controls, and automatic reload when the file changes on disk. Appearance follows system light/dark mode and basic settings let you adjust font, text size and page width.
Distribution is via a Developer ID-signed, notarized DMG; install by dragging to Applications, and updates are manual (Check for Updates opens the release page). The app blocks remote images and renders embedded HTML as text, performing all work locally to preserve privacy, though it is not a security sandbox for untrusted files. Source can be built on an Apple Silicon Mac with Xcode using provided scripts; license is MIT (© 2026 Tim Tairov) and third-party components and security/privacy notes are included in the repo.
