I noticed many MarkText users also need a lightweight viewer for just reading Markdown files without opening a full editor.

That's why I built MDFK — a free Markdown viewer for macOS and Windows.

What it does

• Double-click any .md file to see it rendered instantly
• Supports Mermaid diagrams, LaTeX math, and syntax-highlighted code blocks
• Auto-generated table of contents for long documents
• Export to PDF and HTML
• Works offline, no account needed, completely free

Links

• Desktop app: https://mdfk.app/
• Online editor (free, no login): https://md.mdfk.app/

How it complements MarkText

MarkText is fantastic for editing Markdown. MDFK fills the gap for viewing — when you receive a README, documentation, or notes and just want to read them rendered, without the overhead of launching an editor.

Would love to hear your feedback!
