Multi-Document Editing: Work Across Multiple Word Files at Once

One Document Is Easy. Twenty Is a Problem.

Editing a single Word document is straightforward. But real work rarely involves just one file.

M&A due diligence means reviewing hundreds of contracts. A policy update means changing the same language across every employee handbook, SOP, and training manual. A contract negotiation means keeping the master agreement, schedules, and exhibits all in sync.

Word opens one file at a time. Docmods doesn't.

How Multi-Document Editing Works

Upload Your Documents

Drag and drop multiple .docx files into the chat. Each file gets its own document ID and version history. Upload two files or twenty—the workflow is the same.

Work Across Files

Once your documents are uploaded, you can ask the AI to work across them:

• "Compare the NDA and the MSA. Flag any conflicting confidentiality terms."
• "Update the indemnification clause in all three contracts to match our new standard language."
• "Pull the payment terms from the SOW and check they match the master agreement."
• "Find every reference to 'Acme Corp' across these documents and replace with 'Acme Holdings LLC'."

The AI reads all uploaded documents, understands their structure, and applies edits to the right files.

Download Each File

Every document is edited independently and tracks its own changes. Download them individually, and each has its own tracked insertions, deletions, and comments.

What You Can Do

Cross-Document Comparison

Upload two versions of a contract, or two related agreements, and ask the AI to compare them. It identifies:

• Missing clauses — provisions in one document but not the other
• Conflicting terms — payment terms, deadlines, or definitions that don't match
• Language inconsistencies — the same concept described differently across documents

Discrepancies are flagged as comments in the relevant document, so you can review them in Word.

Batch Consistency Updates

When standard language changes—a new legal clause, updated branding, revised compliance language—you need to apply the same change everywhere.

Upload the affected documents, describe the change once, and Docmods applies it across all files with tracked changes. No manual find-and-replace across dozens of files.

Contract Package Review

Deals often involve a package of related documents: master agreement, schedules, exhibits, side letters. These documents reference each other, and inconsistencies between them create risk.

Upload the full package and ask the AI to check for internal consistency. Are defined terms used the same way everywhere? Do cross-references point to the correct sections? Does the schedule match what the master agreement promises?

Document Merging

Combine content from multiple source documents into a single output. Pull sections from different templates, merge contributions from multiple authors, or consolidate feedback from separate reviewers into one clean document.

Real Workflows

Due Diligence

Upload a set of target company contracts. Ask the AI to:

1. Flag change-of-control provisions across all agreements
2. Identify any contracts with non-standard termination clauses
3. List all documents with assignment restrictions
4. Add comments summarizing the risk in each flagged document

Download the annotated files and hand them to your deal team.

Policy Rollouts

When a regulation changes or a company-wide policy is updated:

1. Upload every affected document (handbooks, SOPs, training materials)
2. Describe the required change once
3. The AI applies consistent tracked edits across all files
4. Review and accept changes per-document

No version confusion. No missed files. Every change is tracked and reviewable.

Multi-Party Negotiations

When multiple parties contribute separate documents to a deal:

1. Upload all contributed documents
2. Ask the AI to flag inconsistencies between them
3. Review the comments, negotiate the resolution
4. Apply the agreed changes across all files

Regulatory Submissions

Submission packages often include multiple documents that must be internally consistent—protocols, consent forms, investigator brochures, and supporting evidence. Upload the set and validate cross-references before filing.

For Developers: The SDK

Multi-document editing is also available through the Python SDK. This is useful for building automated pipelines that process document sets programmatically.

from docxagent import DocxAgent
from agents import Runner

agent = DocxAgent(api_key="your-api-key")

# Upload multiple documents
master_id = agent.upload("master_agreement.docx")
schedule_id = agent.upload("schedule_a.docx")
exhibit_id = agent.upload("exhibit_1.docx")

# Work across all three
result = Runner.run_sync(agent, f"""
Review these related documents:
- Master Agreement: {master_id}
- Schedule A: {schedule_id}
- Exhibit 1: {exhibit_id}

Check that defined terms are used consistently across all
three documents. Flag any cross-reference errors. Add
comments where the schedule or exhibit contradicts the
master agreement.
""")

# Download each
agent.download(master_id, "reviewed/master_agreement.docx")
agent.download(schedule_id, "reviewed/schedule_a.docx")
agent.download(exhibit_id, "reviewed/exhibit_1.docx")

See the background agents use case for more on building automated document workflows with the SDK.
