Features

Tabbed reading

Open multiple markdown files at once and switch between them from the tab bar. Close tabs with a click or keyboard shortcut, and reopen recent files from the sidebar.

Syntax highlighting

Mdow uses Shiki for accurate, editor-quality syntax highlighting across 30+ languages. Both light and dark themes are supported.

Mermaid diagrams

Mermaid diagram blocks are rendered inline — flowcharts, sequence diagrams, class diagrams, and more.

Light and dark themes

Mdow follows your system preference automatically, or you can set a preference manually. The warm light theme uses stone/sand tones, while the dark theme is pure neutral gray.

File tree sidebar

Open a folder and browse its contents in a collapsible tree view. Click any markdown file to view it instantly. Switch between Recents, Outline, and Folder views from the sidebar rail.

Command palette

Press Cmd+K (or Ctrl+K on Windows/Linux) to open the command palette. Jump to files, toggle the sidebar, open settings, and more — without leaving the keyboard. See the shortcuts page for the full list.

Find in document

Press Cmd+F to search within the current document. Matches are highlighted as you type, with keyboard navigation between results.

Live file watching

When you edit a file in your text editor, mdow picks up changes automatically and refreshes the view.

Wide reading mode

Hide chrome and expand the reading column when you want fewer distractions. Toggle wide mode from the toolbar or command palette.

Drag and drop

Drop .md, .markdown, or .mdx files anywhere in the window to open them instantly.
