MDDock opens any existing folder of .md files without an import or proprietary database. Write in a Typora-style live-render editor, ask AI questions grounded in your own notes with source citations, and let Claude Code, Cursor, or Codex read the same vault through skills, MCP, or the TUI. It also includes presenter mode, 13+ reading themes, Office round-trip conversion, and free browser Markdown tools for macOS, Windows, iPhone, and iPad.
