Compare versions of a lease with a privacy-safe AI copy.

To compare versions of a lease, select it locally, review changed clauses, dates, amounts and version markers, replace accepted identifiers with consistent placeholders, and verify the exported copy before sharing it with an AI tool.

Why this workflow matters

Keep the useful context. Remove the unnecessary identity.

A lease can contain tenant and landlord names, property addresses and unit details, account, deposit and contact references. Compare wording and changes without sending the original identifying details to an AI tool. The useful context stays readable while unnecessary identity-bearing details are reviewed before export.

The goal is a working copy that still makes sense to an AI tool: relationships stay consistent, while accepted names, contacts, addresses and document-specific identifiers become controlled replacements.

A practical sequence

From original file to AI-ready copy.

Four checkpoints
01

Select the document locally

Choose a lease from your device. The original stays in the browser while its supported text and image content are prepared for review.

02

Define the AI task

Write down the output you need: changed clauses, dates, amounts and version markers. This keeps the review focused on useful context instead of removing facts blindly.

03

Review document-specific findings

Check tenant and landlord names, property addresses and unit details, account, deposit and contact references, then add any unique value that the detector cannot know from the document type alone.

04

Verify before sharing

Open both exported copies and confirm tracked changes and headings are understandable. Property schedules, floor plans and signature pages deserve a visual check.

Document-specific review

What gets checked before export?

The detector suggests candidates; you decide what changes. For this workflow, start with the fields below and add custom findings when the document contains a unique name, project, matter or identifier.

Document-specific: tenant and landlord names Document-specific: property addresses and unit details Document-specific: account, deposit and contact references Version markers: remove names while retaining dates and revision context Custom values you add for this document

Privacy boundary

What stays on your device.

  • The original document is not uploaded to AnonymizeDocs.
  • Extracted text, findings and replacements remain in the browser session.
  • This page's version comparison guidance is a preparation workflow, not a confidentiality guarantee.

Human checkpoint

What still needs your judgment.

Comparison is only useful when placeholders match across versions and the export preserves the relevant structure. Property schedules, floor plans and signature pages deserve a visual check. Keep the original file unchanged and follow the policies that apply to the document owner.

A verified export confirms accepted values were handled. It does not promise that an automated detector found every sensitive detail.

What a useful output looks like

Readable enough for analysis. Safer to share.

Stable placeholders let the AI distinguish one party from another without receiving the original names. Keep the clauses, dates and relationships the task needs; replace the details that identify the people, companies or matter.

Before you share the copy

Questions people ask about this workflow.

Can I compare versions of a lease without uploading the original?

Yes. Keep revision dates and clause structure while replacing names, contacts and other unnecessary identifiers consistently in both copies.

What should I review in a lease before AI analysis?

Start with tenant and landlord names, property addresses and unit details, account, deposit and contact references. Then check headers, footers, tables, images, filenames and unusual combinations of facts that could identify a person or matter.

Does this make a lease anonymous?

No. It reduces unnecessary identifiers and gives you a reviewed copy. You remain responsible for deciding what can be shared and for checking the final output.
