Matter2

A version control system for office documents.

What is Matter?

Matter is a VCS designed for office documents (DOCX, PPTX, PDF, etc.) rather than source code. It provides:

• ZIP-aware storage — Office formats are unpacked and stored efficiently. A one-word edit to a DOCX doesn't duplicate the entire file.
• Document identity tracking — Rename a file and Matter knows it's the same document.
• Branch and merge — Branch document collections for review cycles. Conflicts are surfaced as side-by-side files for manual resolution.
• Portable format — Export a repository as a self-contained archive.

Installation

pip install matter2

With optional diff support (DOCX/PDF text extraction):

pip install matter2[diff]
