Getting Started

Mdow is a quiet AI markdown reader for Mac, Windows, and Linux. Open Markdown or local HTML files in a focused desktop app, then ask questions about your documents through an installed ACP provider.

Quick start

1. Download Mdow for your platform
2. Install and launch the app
3. Open a Markdown or HTML file, open a folder, or drag documents into the window

Note: Mdow is a viewer, not an editor. Pair it with your favorite text editor for the best workflow.

AI companion

Open the companion to ask about the focused document or an open folder. Add specific files and folders with @ tags when you want tighter context. Mdow connects through an installed provider such as OpenCode or Codex ACP and includes clickable source citations in its answers.

The companion is read-only and does not modify your documents. See the AI companion guide for provider and context details.

Supported formats

• .md — standard Markdown
• .markdown — alternative extension
• .mdx — MDX files (rendered as Markdown)
• .html / .htm — local HTML previews in a sandboxed viewer

Command palette

Press Cmd+K (or Ctrl+K) to search open-folder files and run common actions such as opening a file, opening a folder, toggling the sidebar, switching wide mode, toggling split view, opening settings, or showing keyboard shortcuts.
