docu.md Markdown Viewer

Preview Markdown locally and export polished Word documents with diagrams, editable math, and code highlighting.

docu.md Markdown Viewer is a Markdown preview and document export extension for people who write, review, and share Markdown every day. Open local or online Markdown in the browser, read it as a polished document, and export it when you need a file that is ready for colleagues, clients, classmates, or reviewers. Markdown is fast for drafting, version control, technical notes, project documentation, and AI-generated content. The handoff is where work usually slows down: diagrams become screenshots, formulas lose editability, code blocks need restyling, and tables often need manual cleanup. docu.md keeps the source in Markdown while giving you a finished reading and export surface. Key features: - Clean Markdown reading view for local files and supported web URLs. - DOCX export for editable Word documents. - PDF and self-contained HTML export where supported by the platform. - Editable math formulas in Word output. - Syntax highlighting for code blocks. - Document themes for business reports, academic writing, technical notes, reading layouts, and Chinese typography. - Smart rendering and caching for large documents. - Local processing for normal preview and export workflows. Supported rich content includes standard Markdown, GitHub-style tables and task lists, images, highlighted code, math formulas, SVG content, complex HTML tables, and richer document visuals. To make technical documents more expressive, docu.md supports up to 9 diagram and chart formats, including PlantUML, Infographic, drawio, and ECharts. docu.md is useful for technical documentation, engineering design notes, research drafts, weekly reports, knowledge-base pages, README files, and AI-assisted writing. Save or open the Markdown, review the rendered result, choose a theme, and export the document format that matches the handoff. For local files, enable file URL access in the extension details page. After that, you can open `.md` files from your device, drag files into the browser, or use browser file-open workflows. For online Markdown, open a supported URL and let the extension render the document in place. Privacy is built into the workflow. Normal preview and export processing happens locally in the extension. Your Markdown files do not need to be uploaded to a remote rendering service just to view or export them. Use docu.md when you want Markdown's writing speed with document output that is easier to read, edit, and share.
