Remove PII from a contract before AI upload.

To remove PII from a contract, select it locally, review names, contacts, locations, IDs and combinations of facts that identify the parties, replace accepted identifiers with consistent placeholders, and verify the exported copy before sharing it with an AI tool.

For lawyers, legal operations teams and small-business owners.

Why this workflow matters

Keep the useful context. Remove the unnecessary identity.

A contract can contain party names and roles, addresses and registration numbers, signatures, exhibits and matter references. Use a document-specific checklist to remove direct and contextual PII before upload. 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 contract 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: names, contacts, locations, IDs and combinations of facts that identify the parties. This keeps the review focused on useful context instead of removing facts blindly.

03

Review document-specific findings

Check party names and roles, addresses and registration numbers, signatures, exhibits and matter references, then add any unique value that the detector cannot know from the document type alone.

04

Verify before sharing

Search for known original values and visually inspect pages, images, headers and footers. Signed pages, exhibits and scanned schedules 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: party names and roles Document-specific: addresses and registration numbers Document-specific: signatures, exhibits and matter references Contextual PII: check unique projects, places, dates and narrative clues 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 PII removal guidance is a preparation workflow, not a confidentiality guarantee.

Human checkpoint

What still needs your judgment.

PII detection is a review aid and does not guarantee that every sensitive value or identifying combination was found. Signed pages, exhibits and scanned schedules 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 remove PII from a contract without uploading the original?

Yes. Process a copy locally, review direct and contextual identifiers, export it, and inspect the output before sending it to an AI service.

What should I review in a contract before AI analysis?

Start with party names and roles, addresses and registration numbers, signatures, exhibits and matter references. Then check headers, footers, tables, images, filenames and unusual combinations of facts that could identify a person or matter.

Does this make a contract 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.
