Preview Markdown. Preserve the complex parts. Export finished documents.
docu.md Markdown Viewer opens local or online Markdown as a polished reading page and exports it when you need a document people can actually use. It keeps the source file simple while preserving the parts that usually break during handoff: tables, images, code blocks, math, diagrams, themes, and document spacing.
It is built for technical documentation, engineering notes, research drafts, weekly reports, knowledge-base pages, README files, and AI-generated Markdown that needs final formatting.

Why It Exists
Markdown is fast to write and easy to version. It is also the default format for many AI assistants, developer notes, project reports, and technical drafts.
The problem appears at the handoff stage. A .md file is not always acceptable when a colleague expects a Word document, a reviewer wants a printable PDF, or a client needs a self-contained page. Copying content into another editor often means rebuilding layout, screenshots, formulas, code formatting, and tables by hand.
docu.md bridges that gap. Open the Markdown file, review the rendered result, choose a document style, and export when it is ready.
Rich Content Support
docu.md supports standard Markdown, GitHub-style tables and task lists, images, highlighted code, math formulas, SVG content, complex HTML tables, and diagrams or charts written in common text-based formats such as PlantUML, Mermaid, Vega/Vega-Lite, drawio, Canvas, Infographic, and Graphviz.
That feature list appears here once because it is useful. The rest of the README focuses on workflows, platforms, and practical setup.
What You Can Do
- Open local or online Markdown files in a clean reading view.
- Export finished documents to DOCX, PDF, or self-contained HTML where supported by the platform.
- Keep formulas editable in Word instead of flattening them into screenshots.
- Render diagrams and charts directly from Markdown source blocks.
- Preserve code highlighting, tables, images, headings, and long-form document structure.
- Switch document themes for academic, business, technical, reading, and Chinese typography needs.
- Work with local processing so your documents stay on your device.
Common Workflows
AI Draft to Shareable Document
Paste or save Markdown from an AI assistant, open it with docu.md, review the formatted result, and export a polished document for colleagues, clients, classmates, or reviewers.
Technical Notes to Documentation
Keep architecture notes, project READMEs, API drafts, and visual blocks in Markdown. Preview them with formatted code and rendered content before sharing.
Reports and Research Drafts
Use Markdown for writing speed, then export documents with tables, formulas, headings, and document themes preserved for review or submission.
Document Output
docu.md focuses on the handoff formats people ask for after the writing is done:
- DOCX for editable Word documents.
- PDF for print-ready sharing where supported.
- HTML for self-contained publishing where supported.
- Image/vector exports for rendered visual blocks where supported.
Exact output options vary by platform. See the platform docs for the environment you use.
