Use AI on Real Case Contracts & Client Files — Without Sending Names to LLM Servers
AI Summary / Key Takeaways
"PrivacyScrubber secures Attorney-Client Privilege during generative AI legal reviews. As an offline client-side redaction gateway, it masks witness details, case numbers, and financial agreements locally in RAM before litigation datasets or drafts are analyzed by third-party LLMs."
Interactive PII Detection & Sanitization Sandbox
Test real-time client-side RAM tokenization. Choose a specialized preset or paste your own raw prompt to test instant reversible redaction.
Enterprise-Grade AI Privacy
Add custom redaction rules and priority support with PRO.
"Attorney-Client Privilege is the foundational standard of the legal profession, yet it is uniquely vulnerable when lawyers upload unmasked case files into generative AI tools. Every time a deposition or NDA draft is pasted into public models like ChatGPT, you risk waiving confidentiality, potentially triggering ABA Rule 1.6 violations and jeopardizing high-stakes litigation. PrivacyScrubber introduces a verifiably secure, 100% offline sanitization bridge. It automatically redacts litigant names, financial settlements, and custom case numbers within your browser's local memory before the text ever connects to the cloud. You get the immense speed of AI legal review while safeguarding privilege."
Strategy Insight for Legal Leadership
Scaling AI adoption within Legal environments requires a fundamental shift in data governance. Our enterprise AI solutions ensure that while teams use high-velocity LLMs, the underlying legal data remains fully sovereign. This solution integrates directly with your Legal industry guides to provide an automated privacy layer.
The core challenge for Legal leaders is balancing utility with liability. Standard Cloud DLP filters often strip too much context or require trust in third-party servers. PrivacyScrubber's zero-trust model for enterprise data governance preserves the semantic structure of your prompts locally, ensuring that AI reasoning remains accurate while personally identifiable information (PII) is deterministically masked.
Legal Critical Compliance Vulnerabilities
Uploading unmasked discovery files or NDA drafts to public AI models triggers a direct waiver of attorney-client privilege.
Manual redaction of privilege-heavy legal documents is dangerously slow, creating bottlenecks in litigation prep.
Generic cloud DLP tools lack the legal context to protect sensitive case numbers, witness details, and judge names.
Law firms risk disbarment and malpractice suits if confidential client secrets enter third-party AI training datasets.
PrivacyScrubber keeps all sanitization offline, designed to support compliance with ABA Model Rule 1.6.

Legal Input Neutralization
"Legal teams must protect case numbers, witness identities, and attorney-client privileged information before using LLMs for discovery or deposition analysis. PrivacyScrubber enforces local redaction to prevent accidental waiver of privilege."
Instantly mask Legal identifiers in text, PDF, and DOCX files locally before transmission to any AI provider.
Hardware-level verification ensures no data packets leave your browser RAM session during the redaction process.
Audit Roadmap: Legacy Cloud-DLP vs. ZTDS
| Strategic Metric | Legacy Cloud-DLP | ZTDS (PrivacyScrubber) |
|---|---|---|
| Data Perimeter | Transmitted to Cloud API | 100% Local (Client-Side) |
| Processing Latency | 500ms - 2500ms (Network) | < 15ms (Native JS) |

The Airplane Mode Standard
Disconnect your network, enable Airplane Mode, and watch PrivacyScrubber maintain 100% operational integrity. This is not just a feature—it is a verifiable proof that your Legal records never leave your control.
Solving Legal Challenges with Enterprise Governance
Scale Zero-Trust Data Sanitization across your entire organization with centralized enforcement and native browser integration.
CISO / Compliance
In the Legal sector, enforcing Zero-Trust is mandatory. With the PrivacyScrubber Chrome Extension, administrators deploy data masking via MDM to all endpoints. Preventing local model leakage ensures that when employees use GenAI, sensitive legal records are never exfiltrated to external LLM servers, instantly satisfying compliance and governance audits.
Operations Lead
Legal organizations require agile collaboration without compromising privacy. The Enterprise Governance model features encrypted Session Sharing, allowing CISOs and managers to securely distribute custom Regex dictionaries across the department. This enforces uniform data redaction standards across all GenAI workflows, eliminating human error while maintaining high velocity in team-based AI adoption.
Edge Analyst
Daily legal operations rely on continuous efficiency. The native extension automates PII scrubbing directly at the browser input field, ensuring analysts never waste time manually censoring data. This automated integration provides zero server latency, enabling end-users to confidently use ChatGPT and Claude for immediate Legal insights.
