Legal Teams: Zero-Trust Contract Redaction for ChatGPT

Legal Teams: Maintain attorney-client privilege while using ChatGPT. Redact client names, deal values, and confidential contract terms natively in the browser.

Legal Teams: Zero-Trust Contract Redaction for ChatGPT

Attorneys, general counsel, and contract managers use AI to redline complex commercial agreements, analyze indemnity clauses, and summarize case law. PrivacyScrubber's Legal Extension protects attorney-client privilege by sanitizing client names, deal amounts, and proprietary clauses before prompts leave the law firm's local network.

Attorney-Client Privilege Defense & Contract Tokenization

Tokenizes client names, counterparty entities, monetary settlement figures, and proprietary patent disclosures in <2ms local browser memory.

● IN-PAGE SANDBOXED INTERCEPTION Intersects DOM input before network transmission. Evaluates regex in <2ms browser RAM.
● 3-LINE LOOKAHEAD STITCHING Automatically re-assembles entities split across linebreaks before tokenization.
● REVERSIBLE TOKEN MAP Substitutes raw PII with reversible tokens ([NAME_1], [ID_1]) for instant 1-click restore.
● ADMIN BLUEPRINT LOCK Enterprise policies deploy with [ENTERPRISE LOCKED] badge — tamper-proof for staff.

Defending Third-Party Disclosure Privilege Waivers

Under US and international legal standards, sharing unencrypted client communications or draft agreements with third-party cloud AI vendors can constitute a waiver of attorney-client privilege. PrivacyScrubber's browser extension intercepts legal text, substituting client names with [CLIENT_ENTITY_1] and transaction amounts with [TRANSACTION_VALUE_1], allowing attorneys to analyze clauses without waiving privilege.

Commercial Contract Indemnity Clause Redline

  1. 1
    Copy or Paste Unsanitized Content: Attorney pastes 20-page Master Services Agreement (MSA) containing client corporate name, counterparty name, and liability caps.
  2. 2
    Real-Time In-Browser Sanitization: The extension replaces party names with [PARTY_A] and [PARTY_B] while leaving all governing law, indemnity, and arbitration terms intact.
  3. 3
    Submit to LLM with Zero Cloud Exposure: Attorney prompts ChatGPT: "Analyze limitation of liability enforceability under Delaware law for [PARTY_A]". AI performs legal analysis.
  4. 4
    Instant Local Reversal (Contextual Reveal): Attorney restores actual party names via 1-click in-page reveal and exports redlined agreement for client review.

ABA Model Rule 1.6 (Confidentiality of Information) Compliance

American Bar Association (ABA) Model Rule 1.6 requires lawyers to make reasonable efforts to prevent inadvertent disclosure of client information. Local edge tokenization satisfies Rule 1.6 requirements, following our Legal AI Compliance framework.

Offline Parsing of Large Multi-Party Agreements

Parse multi-hundred page PDF loan agreements and merger filings locally in browser memory without sending un-redacted documents to cloud servers, as detailed in attorney-client privilege in AI and protecting DOCX contracts.

Privilege Defense Audit Receipts

Generate cryptographic audit receipts proving that contract analysis prompts contained zero identifiable client information, meeting enterprise data governance standards.

Latest Capabilities: Multi-Line Stitching & Local OCR

The PrivacyScrubber Chrome Extension features a smart 3-Line Name-Stitching Lookahead to capture names split across lines (e.g. Firstname MiddleInitial Surname) in scanned medical/clinical records, NDAs, and PDFs. It also supports Local Wasm OCR & PDF Sanitization to redact text from screenshots/PDFs offline, and Zero-Trust Session Sync (Argon2id + XChaCha20-Poly1305) to share rules peer-to-peer securely.
