How to Redline in Word: Manual Steps vs AI Automation

Published June 19, 2026 · 8 min read

Redlining a contract in Microsoft Word is the de facto standard for negotiating commercial agreements. It works — but it’s slow, error-prone, and rarely consistent with your playbook. This guide walks through the manual workflow step-by-step, then shows how an AI Redline Agent cuts the cycle from days to minutes while keeping a full audit trail.

What “redlining” actually means

A redline is a marked-up version of a contract showing every proposed change against an agreed baseline. In Word, redlines are produced with the Track Changes feature: insertions, deletions, formatting changes, and comments are all attributed to the editor and timestamped. Counter-parties exchange redlined drafts until both sides accept every change — at which point the document is “clean” and ready for signature.

The manual workflow in Microsoft Word

1. Turn on Track Changes. Go to Review → Track Changes (shortcut: Ctrl + Shift + E on Windows, ⌘ + Shift + E on Mac). Lock it with a password if you don’t want the other side disabling it.
2. Set the markup view. Use All Markup while editing so every change is visible. Switch to Simple Markup for a cleaner read, or No Markup to preview the final wording.
3. Make your edits. Insertions appear in your author colour; deletions are struck through. Use New Comment for rationale, alternative language, or open questions. Keep one issue per comment so threads stay readable.
4. Compare against the baseline. When the counter-party returns a new draft, use Review → Compare to generate a redline against your last sent version. This catches silent edits made with Track Changes off.
5. Resolve, accept, reject. Walk through each change with Next / Previous and click Accept or Reject. Resolve comments as you go.
6. Produce a clean copy. Once every change is accepted and every comment resolved, Save As a new file and circulate for signature.

Where the manual process breaks down

• Playbook drift. Reviewers rely on memory — or a 60-page PDF playbook — to know that indemnity should be capped at 2× fees and payment terms should be Net-45. Edits routinely miss the mark.
• Version sprawl. MSA_v3_final_FINAL_redline_DT_clean.docx is not a joke. Three rounds in, nobody is sure which draft is current.
• Silent edits. A counter-party can disable Track Changes, edit a numeric cap or carve-out, and re-enable it. Compare catches this — but only if you remember to run it every round.
• No audit trail. Word’s author attribution is only as good as the user’s licence display name. There’s no immutable record of who proposed what and why.
• Slow turnaround. Industry benchmarks put a typical MSA redline round at 3–5 business days. For a five-round negotiation, that’s a month.

AI-assisted redlining: what changes

An agentic redline tool reads the incoming draft, compares every clause against your written playbook, and proposes Track Changes-compatible edits with rationale and citations. The lawyer still decides — but they review a pre-marked draft instead of starting from scratch.

Manual vs AI-assisted: a side-by-side

Practical tips for Word redlines (whichever path you take)

• Always lock Track Changes before sending out a draft.
• Run Compare on every returned draft, even if Track Changes appears intact.
• Keep comments numbered and tied to a clause reference — easier to discuss on a call.
• Save a clean version after each round; don’t stack ten rounds of markup in one file.
• Standardise author display names across the team so attribution is consistent.
