Document Redlining
Transform your documents with intelligent editing while maintaining full visibility into every change. Our redlining capability brings attorney-grade precision to document modifications.How Redlining Works
Upload Your Document
Upload any Word document (.docx or .doc). Legacy .doc files are
automatically converted for processing.
Describe Your Changes
Tell us what changes you want in plain language. Be as specific or general
as needed.
What You Can Ask For
Simple Changes
“Change the governing law from Delaware to Texas.”
“Replace all instances of ‘Acme Corp’ with ‘XYZ Inc’.”
“Update the effective date to January 1, 2025.”
Complex Modifications
“Strengthen the confidentiality provisions to include derivative works and extend the term to 5 years.”
“Add a force majeure clause covering pandemics, natural disasters, and government actions.”
“Revise the indemnification section to be mutual instead of one-way.”
Section-Specific Edits
“Edit only Section 4 to add a 30-day cure period.”
“In Section 2.1, change the payment terms from Net 30 to Net 45.”
“Modify only the termination clause to require 90 days written notice.”
Section-Aware Editing
When you specify sections, we take it literally:What You Say
“Edit only sections 2 and 4 to make the language more formal”
What Happens
Changes are restricted to sections 2 and 4 only. All other sections remain
untouched.
How It Works
- Section Detection: We analyze your document structure to identify all sections
- Instruction Mapping: Your request is mapped to specific sections
- Targeted Editing: Changes are applied only where specified
- Compliance Verification: We confirm changes stayed within boundaries
If you don’t specify sections, changes are applied wherever contextually
appropriate throughout the document.

(enabled by default)
Source Citations (Automatic)

AI Analysis
Changes inferred from context and best practices
User Feedback
Changes driven by preferences learned from your previous reviews
¹ Source: User Request - Change company name to Acme Corp
Footnotes appear at the bottom of each page and are automatically numbered.
You can disable them by adding “without footnotes” to your request.
Interactive Redline Review
Open any redline in the built-in Redline Review page to review changes without leaving mixus:Accept / Reject
Accept or reject each change to build your final client document. Works like
Word’s Track Changes pane.
Rate AI Suggestions
Rate each AI suggestion as Helpful or Not Helpful. The AI learns your
preferences automatically for future redlines.
Edit Inline
Edit replacement text directly in the review page. No need to open Word for
small tweaks.
How the Review Page Works
- Left sidebar shows all tracked changes. Accept or reject each one using the checkmark and X buttons (or press
A/Ron your keyboard). - Center pane renders the document in Word View or PDF View. Click any tracked change to select it.
- Right panel shows the AI’s reasoning, source citation, and a “Rate This AI Suggestion” section where you can mark changes as Helpful or Not Helpful.
- Footer shows a live download bar. Once you’ve made decisions, click “Download Final Document” to get your updated DOCX with all accepted changes applied.
Smart Defaults
When you Accept a change, the AI feedback is automatically set to “Helpful.” When you Reject, it’s set to “Not Helpful.” This means 90% of the time you don’t need to touch the AI feedback at all — the AI learns from your accept/reject decisions automatically. You can override the default by clicking in the right panel. For example, you might Accept a change for the client but mark it “Not Helpful” to tell the AI not to suggest that type of change normally.Download Options
The review page offers multiple download options:| Download | Description |
|---|---|
| Original Document | Clean version before any AI changes |
| AI Redline (Track Changes) | The redlined DOCX with markup |
| Redline with Comments | Track changes + source citations as Word comments |
| Comparison PDF | Side-by-side comparison |
| Final Document | Your document with accepted/rejected changes applied |
AI Learning
Every time you review a redline, your feedback is saved and used to improve future redlines. The AI learns:- Which types of changes you prefer for different document types
- Where the AI over-corrects or under-corrects
- Your organization’s specific preferences (e.g., preferred governing law, liability caps)
Working with Track Changes in Word
The redlined document also works with standard Word features:- Accept/Reject: Use Word’s built-in buttons to accept or reject individual changes
- Review Pane: See all changes in Word’s review pane
- Source Citations: Check page bottom for footnotes explaining each change
- Compare: Compare against other versions using Word’s compare feature
- Print: Print with or without markup visible
Version Tracking
When you make multiple rounds of changes in the same chat, each version is automatically tracked with professional legal naming:File Naming Format
| Round | What You Get |
|---|---|
| 1st | Redline - Contract (v1) 2026-01-04.docx |
| 2nd | Redline - Contract (v2) 2026-01-04.docx |
| 3rd | Redline - Contract (v3) 2026-01-04.docx |
How It Works
Automatic Versioning
Version numbers increment automatically each time you request changes on the
same document within a chat.
Clear History
Easily identify which version is which during multi-round negotiations.
Example Chat Progression
Each document is tracked independently. If you have multiple documents in the
same chat, each has its own version counter.
Document Comparison
Need to compare two existing documents instead of making new changes? Use our Document Comparison feature to:- Compare original and signed versions
- Generate a redline between v1 and v2
- See what changed between drafts
Learn About Document Comparison
Compare two documents without AI editing—just show the differences.
Quality Assurance
Every redline goes through our validation process:Controlling Source Citations
Enable (Default)
Source citation footnotes are enabled by default. Just make your request normally:“Change the governing law to California”Result: Tracked change + footnote showing source
Disable
Add “without footnotes” or “no source citations” to your request:“Change the governing law to California without footnotes”Result: Tracked change only, no footnotes
Best Practices
Be Specific When Needed
”Change the payment term from Net 30 to Net 45 in Section 3.2"
Use Section References
”In the Termination section, add a 30-day cure period"
"Edit only Section 5.1 to require written notice”
Describe the Intent
“Make the confidentiality provisions stronger to protect trade secrets”
“Add standard force majeure language covering natural disasters and government
actions”
