👁

Live Preview

Side-by-side editing and rendered preview. See your Markdown come alive as you type — headers, code, lists, links.

📑

Tabs

Work on multiple files at once with a tabbed interface. Switch between documents without losing your place.

🎨

Syntax Highlighting

Rich color-coded Markdown syntax makes your source readable. Headings, bold, code blocks — all visually distinct.

🧜‍♀️

Mermaid Diagrams

Write flowcharts, sequence diagrams, and more in Markdown. MarkMoose renders Mermaid blocks right in the preview.

🌙

Dark Mode

A carefully crafted dark interface that's easy on your eyes during long writing sessions. Because you deserve better than blinding white.

📄

Native .md Files

Double-click any .md file and it opens in MarkMoose. Full Windows file association — it just works.

Double-click
and write

MarkMoose registers as the default handler for .md files on Windows. No need to open an app first — just double-click your file and you're in.
