PrivacyScrubber — PII Masking & AI Redaction

Local AI privacy & PII anonymizer. Mask names, API keys, PDFs & sensitive data in browser RAM before AI chats. Zero server egress.

Anonymize sensitive text, documents, and personal identifiable information (PII) locally in browser RAM before sending prompts to generative AI assistants. PrivacyScrubber works as a client-side privacy anonymizer and data masking shield directly inside web chat interfaces such as ChatGPT, Claude, and Google Gemini — with zero cloud uploads. Pasting raw client records, patient notes, tax schedules, or source code secrets into third-party AI tools exposes confidential data to external servers and cloud logging. Operating at the browser input layer for instant data loss prevention (DLP), this extension replaces sensitive entities with structured surrogate tokens ([NAME_1], [EMAIL_1]) prior to submission, then restores the original values in one click when the assistant replies. Free to start with no account required. Verified operational offline in Airplane Mode. INLINE WORKFLOW ACROSS WEB AI & SUPPORT TOOLS • Conversational AI Chat Boxes: Injects an inline Shield button into the prompt composer on ChatGPT and Claude so practitioners can redact text and reveal tokenized replies in place without switching tabs. • Workspace & Search Assistants: Supports in-page PII redaction and local token restoration inside browser assistants including Gemini, Microsoft Copilot, and Perplexity. • Helpdesk & Universal Web Forms: Masks customer details inside Zendesk ticket composers and works across any standard web form or CRM field via keyboard shortcut (Alt+Shift+X). LOCAL DOCUMENT & OCR SANITIZATION (ZERO UPLOAD) • Drag-and-Drop File Masking: Sanitize PDF, DOCX, CSV, and TXT files up to 25MB directly in local memory using WebAssembly workers and offline image OCR. • Multi-Tab RAM Isolation: Every browser tab maintains an isolated volatile token map in memory and clears it automatically when the tab closes. WHAT THIS EXTENSION DETECTS & REDACTS • Contact & Identity Records: Full names, work and personal emails, international phone lines, street addresses, Social Security IDs, tax identifiers, and passport details. • Healthcare & Clinical PHI: De-identification of medical record identifiers (MRN), patient names, and clinical notes aligned with HIPAA Safe Harbor workflows. • Accounting, Finance & Payments: Payment card digits, IBANs, bank routing codes, payroll tables, and audit workpapers aligned with PCI DSS and GLBA standards. • Legal & HR Documents: Case references, contract party names, attorney-client privilege markers, and candidate resume details. • Engineering Credentials: Cloud API keys, bearer tokens, private keys, and database connection strings. HOW IT WORKS IN 3 STEPS 1. Type or Drop a File: Enter your prompt in a supported chat composer or drop a PDF, DOCX, or CSV document for local parsing. 2. Click Shield (or Press Alt+Shift+X): Sensitive values are replaced in RAM with readable tokens ([NAME_1], [ID_1]) while preserving sentence structure. 3. Submit & Reveal: Send the tokenized prompt. When the AI replies using those tokens, click Reveal to restore the original cleartext locally on your screen. COMPLIANCE EVIDENCE & TEAM GOVERNANCE • CISO Audit Receipts: Export local PDF audit certificates with cryptographic session digests documenting technical risk minimization for GDPR (Art. 32), HIPAA, SOC 2, and ISO 27001 reviews. • Encrypted Team Handoff: Share tokenized session maps across authorized colleagues using end-to-end authenticated session encryption with zero server storage. PLANS & ACCESS • Free Tier: General Profile (up to 15,000 characters per scrub), 5,000-character per-scrub trial quota across 30 specialized industry profiles, single TXT/DOCX redaction, and 1-click reverse reveal. • PRO & TEAMS Licenses: Optional paid upgrades unlock unlimited character throughput across all 30 industry profiles, batch file processing, offline PDF/image OCR, custom regex rules, and team governance.
