The aftercare for AI-written markdown

AI writes it.
docu.md does the rest.

Turn AI-generated markdown into work you can hand in, send out, publish, or present. Beautiful reading, rich diagrams, and polished DOCX/PDF/HTML output across the platforms you already use.

Browser Obsidian VS Code Mobile

AI writes .md by default.

ChatGPT, Claude, Copilot — every AI outputs markdown. It's fast, clean, and version-control friendly. But when you need to share with a colleague, submit to a journal, or present to a client, you hit a wall. Markdown files aren't documents.

docu.md bridges the gap.

Open any .md file and see it beautifully rendered — live diagrams, formatted code, editable math. Export to polished DOCX, PDF, or HTML in one click. No manual formatting. No copy-paste. Just your content, delivered professionally.
