Get AI edits to a Word document as tracked changes
AI tools on a Mac that edit Word documents as tracked changes: Claude for Word, Copilot in Word and Nudocs, and what to check before you send the file.

Short answer
Ask for the edits as tracked changes, so each AI change arrives as an insertion or deletion you can accept or reject. Inside Word on a Mac, Anthropic’s Claude for Word add-in has a tracked changes mode, and Microsoft documents tracked-change redlines from Copilot in Word when its legal skills are on. Outside Word, you can ask Nudocs for a focused revision to a DOCX as tracked changes. Whichever you use, reopen the file and check the redline before you send it.
Why ask for tracked changes
An AI rewrite that replaces text in place leaves you to work out what changed. Tracked changes keep the edit reviewable: deleted text stays visible as a deletion, new text shows as an insertion, and you decide what to keep. The other side of a negotiation sees the same marks.
In Word for Mac, you turn this on with Review > Track Changes. Switch to All Markup to see changes inline and in balloons, then accept or reject them with Reviewing > Accept or Reviewing > Reject. Review an AI edit the same way you would review a colleague’s.
Claude for Word
Claude for Word is Anthropic’s add-in for Microsoft Word. Anthropic lists Word on Mac version 16.61 or later as supported. You install it from its Microsoft AppSource listing and sign in with a Claude account.
In tracked changes mode, Anthropic says Claude’s edits land as tracked revisions: the original text shows as a deletion and the new text as an insertion, reviewable in Word’s own review pane. It can also work through comment threads, editing the text each comment is anchored to and replying with what it changed, and it can summarize a counterparty’s redlines.
Anthropic adds two cautions. It recommends using the add-in only with trusted documents, because files from outside sources can contain hidden instructions, and it doesn’t recommend it for final client deliverables or counterparty sends without human review.
Copilot in Word
In Word for Microsoft 365 for Mac, Copilot can rewrite, reorganize, format or summarize text you select. You review the result, then choose Replace, Insert below or Regenerate. Microsoft notes that Copilot may not be included with your Microsoft 365 subscription, or may be unavailable because of your organization’s settings.
For redlines, Microsoft’s Copilot for legal guide says that with legal skills turned on, Copilot in Word desktop proposes edits as tracked changes that you accept or dismiss. That guide lists a Microsoft 365 Copilot commercial license as a prerequisite and doesn’t say whether Word for Mac is included, so check in your own copy of Word.
With Nudocs
Nudocs is a document agent for your Mac. You can ask it for a focused revision to a DOCX and request tracked changes, so the edits arrive as a redline you can review in your usual app.
Open the existing document and note any comments and revisions already in it. Describe the edit, explicitly ask for tracked changes, and say which terms must stay unchanged. Read the proposed edits in context, then reopen the exported DOCX in your review application.
Review history and export behavior need particular care. Don’t assume every existing comment, revision or author detail survives the round trip; verify the exported file against your review requirements before you send it.
Nudocs runs on Macs with Apple silicon and macOS 13 or later, and you need a Nutrient DWS account. The Mac app is free; document and AI services use DWS free allowances or paid usage. Depending on the task, your instructions and document content may be sent to AI providers and Nutrient services, so read the desktop Privacy Policy before you add files.
Example request
“In this consulting agreement, change the payment term in clause 5.1 from 45 days to 30 days and update the late-payment clause in 5.3 to match. Make these tracked changes and leave the fees and scope unchanged.”
Before you use it
What to check
- Open the exported file in Word and switch to All Markup, so every AI edit shows as a tracked insertion or deletion.
- Make sure no edit arrived as plain new text without a revision mark.
- Check the author name on the new changes before the file goes to anyone else.
- Confirm that existing comments and earlier revisions are still there.
- Read each change with the clauses around it, including numbering and cross-references.
Questions
- Can AI edit a Word document with tracked changes?
- Yes, if the tool supports it and you ask for it. Anthropic documents a tracked changes mode in Claude for Word, Microsoft documents tracked-change redlines from Copilot in Word with legal skills turned on, and Nudocs can make a focused revision to a DOCX as tracked changes. Review each change before you accept it.
- Does Claude for Word work on a Mac?
- Anthropic lists Word on Mac version 16.61 or later as supported. You install the add-in from its Microsoft AppSource listing and sign in with a Claude account.
- Will existing comments and revisions survive an AI edit?
- Don’t assume they will. Reopen the edited DOCX and check existing comments, earlier revisions and author details before you pass it on.
- What do I need to use Nudocs?
- A Mac with Apple silicon running macOS 13 or later, and a Nutrient DWS account, which you sign in to the first time the app opens. The Mac app is free. Document and AI services use DWS free allowances or paid usage, depending on your plan and task.
