office-word-diff

When to Use

• You need to apply AI-generated edits as tracked changes in Word documents
• You're building a legal tool that produces DOCX output with redlines
• You need deterministic, word-level text comparison (not just line-level diff)
• You want to preserve formatting through document transformations
• You're integrating with Claude Code, Cursor, or other agents that produce document changes

How It Works

Core Problem

Most diff tools operate at the line or paragraph level. Word documents have structural complexity — nested lists, tables, headers, formatting runs — that line-based diffs destroy. office-word-diff solves the kernel-level problem: applying word-level tracked changes to DOCX while preserving formatting.
