Mutandis: Word’s Compare, without Word
Mutandis compares Word-document drafts and produces a tracked-changes redline locally, with a Windows app, command-line tool, and MCP server for Claude.
- For
- Contract reviewers comparing Word drafts
- Worth noticing
- The site says accepting every tracked change yields the revised draft, while rejecting every change yields the original.
Field notes
The sample interface uses a folder of successive NDA drafts and displays counts for insertions, deletions, moves, and formatting changes. The page describes Word-like comparison choices including whole-word boundaries, clause moves, and matching table rows by similarity. It also says the installer works for the current user without administrator rights; the stated local-processing and round-trip testing claims are not independently verified by the extract.
