Microsoft Word Copilot adds new revision tracking, AI document editing finally leaves traceable and auditable records

ME News, April 15 (UTC+8), according to Beating Monitoring, Microsoft CEO Satya Nadella announced today that Word Copilot has gained a set of new features aimed at highly sensitive document scenarios. The core change is that Copilot’s editing operations can now enable Track Changes, recording every modification with word-level precision, making it reviewable and reversible. Previously, Copilot’s edits in Word were directly overwriting content, and users couldn’t audit each change made by AI, which was almost unusable in contract review, compliance document finalization, and similar scenarios.

In addition to Track Changes, Copilot also introduces the following capabilities:

1. Commenting feature: can read, reply to, and manage comment threads in documents, with comments anchored to the corresponding text
2. Automatic generation and updating of tables of contents based on Word’s built-in heading styles
3. Management of dynamic page elements such as headers and footers, columns, margins, page numbers, and dates
4. Real-time progress indicators during multi-step editing, informing users which step is currently being processed

These features are based on Microsoft’s Work IQ layer, adhering to Microsoft 365’s data security boundaries, retaining sensitivity labels, and enforcing data loss prevention policies. Currently, they are only available on Windows desktop through the Frontier program, with Mac and web versions to follow later.

Track Changes is the most critical update in this release. Legal, financial, and compliance teams often require complete audit trails of modifications in documents, which are mandatory for regulatory and internal processes. Previously, Copilot lacked this capability, meaning these teams either didn’t use AI or had to manually compare each segment after use. Now, Copilot works directly in review mode, with editing marks and human edits formatted consistently, allowing seamless integration into existing review workflows.
