# docu.md

> Read Markdown and export polished documents with diagrams and math

docu.md is a free, open-source Markdown viewer and document export tool for turning notes, technical writing, and AI-generated drafts into files people can read and share. It renders tables, highlighted code, mathematical formulas, and diagrams from formats such as Mermaid, PlantUML, and Graphviz. Users open a local file or online document, review the formatted page, and choose a theme before exporting.

Word exports retain editable equations, while PDF, self-contained HTML, and EPUB output are available where supported by the platform. Browser extensions and integrations for Obsidian and VS Code bring the workflow into existing writing environments. Normal preview and export processing happens locally, making it useful for preparing reports, research notes, and documentation without manually rebuilding their formatting.
