How it works

Any document β†’ Markdown β†’ any output

MDDock turns your files into searchable, linkable, version-controlled plain text first. Then it works for you.

Import anything

Word, PDF, PowerPoint, Excel, EPUB, web pages β†’ clean Markdown, with metadata preserved in frontmatter.

Markdown is the source

Your files are no longer binary black boxes. Every note is plain text you can search, link, and sync with git or Dropbox.

Export anywhere

The same .md files become Office documents, Marp slides, web pages, or PDF, only when humans need familiar formats.

AI can actually read it

LLMs answer from your Markdown notes, cite your past judgments, and write drafts that stay in your vault.

Vibe Work

Prompt to document in seconds

Type what you need, MDDock generates a full Markdown document, then exports to any format.

Office round-trip

Why MDDock

Office workflows, without losing the source.

The desktop app is the product. Browser tools below are a free taste, nothing uploaded.

Markdown office suite

  • βœ“Export back to Office when humans need familiar formats
  • βœ“Scenario wizards (meeting, PRD, blog, retro) start structured drafts in seconds

Memory that grows with you

Every person, project, and idea you mention in a note gets automatically remembered. Next time you write, the β€œmaybe related” sidebar pulls up older passages automatically. When you chat with AI, it cites not generic knowledge but the half-finished judgment you wrote three weeks ago. Your vault is its long-term memory, keep writing, and it grows on its own.

  • βœ“Hybrid recall (keyword + meaning) across every note in the workspace
  • βœ“Passive β€œmaybe related” hints in the editor, dismissable, never blocking
  • βœ“Chat suggests first questions from your recent notes
  • βœ“Save answers back into the vault β†’ the next round gets smarter
