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.
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.
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.

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
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.
