Marko Viewer

A clean, read-only Markdown viewer.

Marko Viewer renders your Markdown files beautifully so you can focus on reading, not editing. Open any .md file from Finder or the Files app and get a clean, native reading experience.

Whether you're reviewing documentation, reading notes, or browsing a project's README, Marko Viewer stays out of your way. Each file opens in its own window, rendered with GitHub-style formatting that handles headings, code blocks, tables, and more.

Features

• GitHub-style rendering — headings, code blocks, tables, lists, and inline formatting rendered natively.
• Inspector panel — document outline, word count, reading time, and frontmatter metadata at a glance.
• In-document search — find text and navigate between matches with keyboard shortcuts.
• YAML frontmatter — title, tags, and status are parsed and displayed automatically.
• Relative link navigation — click a relative .md link and it opens in a new window.
• Adjustable font size — increase, decrease, or reset. Your preference persists across sessions.
