PrivacyScrubber — PII Masking & AI Redaction

Description

Local AI privacy & PII anonymizer. Mask names, API keys, PDFs & sensitive data in browser RAM before AI chats. Zero server egress. Redact sensitive data, confidential records, and personal identifiable information (PII) before sending prompts to generative AI assistants. PrivacyScrubber automatically masks names, emails, national IDs, medical records, financial figures, API keys, and developer secrets — 100% locally inside your browser's Random Access Memory (RAM). No external servers. No cloud proxies. Zero prompt data ever leaves your device. Your daily prompts often contain sensitive information: client names, customer emails, payroll numbers, patient medical records, or internal API tokens. Pasting unmasked text into third-party AI interfaces exposes confidential data to external servers, cloud logging, and potential training ingestion. PrivacyScrubber intercepts sensitive text directly at the browser input layer, replacing confidential details with safe surrogate tokens (such as [NAME_1], [EMAIL_1]) before submission. When the AI returns its response, click Restore to rehydrate the original values locally in one click. Free to use. No account required. Verified operational offline in Airplane Mode. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ COMPATIBILITY & SUPPORTED INTERFACES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PrivacyScrubber provides an integrated in-page Shield HUD compatible with major web AI chat tools and enterprise web forms: • Web AI Chat Assistants: Direct in-page Shield integration with leading web-based conversational AI assistants. • Enterprise Helpdesk: Direct support for customer support ticketing and composer forms. • Universal Web Popover: Redact text and mask sensitive data on any web page, CRM, or form via keyboard shortcut (Alt+Shift+X). ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ NEW IN V2.2.6: LOCAL DOCUMENT SANITIZATION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Drag & Drop File Sanitization: Drop PDF, DOCX, and TXT documents directly into supported AI chats. • 100% Client-Side Parsing: Document extraction and PII masking occur entirely inside local browser memory via WebAssembly. • Zero Cloud Upload: Your raw files are never uploaded to any third-party conversion server. • Handles files up to 25MB locally with instant token substitution. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT PRIVACY SCRUBBER REDACTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PrivacyScrubber automatically detects and sanitizes sensitive data entities: • Personal Contact Details: Full names, personal and work emails, international phone numbers, and physical addresses. • Government & National Identification: Social security numbers, tax identification numbers, driver's licenses, and passport credentials across major jurisdictions. • Healthcare & Medical Records: HIPAA Safe Harbor identifiers including medical record numbers (MRN), patient IDs, treatment dates, and clinical notes. • Financial & Payment Information: Credit and debit card numbers (with Luhn validation), bank accounts, IBANs, routing numbers, and compensation figures. • Software Credentials & Secrets: Cloud API keys, authorization tokens, private encryption keys, database connection strings, and administrative credentials. • Legal & Confidential Documents: Attorney-client privilege designations, case codes, settlement amounts, and internal ticket references. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS: 3-STEP ZERO-TRUST WORKFLOW ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Enter Your Prompt or Drop a File: Type or paste your prompt into any supported AI chat interface, or drag a PDF/DOCX file into the chat box. 2. 1-Click Shield Protection: Click the PrivacyScrubber shield button (or press Alt+Shift+X). Sensitive entities are instantly replaced with surrogate tokens ([NAME_1], [EMAIL_1]). 3. Safe Ingestion & 1-Click Reveal: Submit the sanitized prompt.

A: No. PrivacyScrubber replaces your real names, numbers, emails, and secrets with surrogate tokens ([NAME_1], [PHONE_1]) before the prompt is sent over the network. The AI model only receives the sanitized tokens. Q: Does PrivacyScrubber send my data to its own servers? A: Never. PrivacyScrubber operates with zero server infrastructure for prompt processing. All regex matching, parsing, and tokenization occur locally in your browser's RAM. You can disconnect your network (Airplane Mode) and confirm that sanitization works completely offline. Q: How do I restore the original values after the AI responds? A: When the AI model replies using the surrogate tokens, click the Reveal button in the chat interface. PrivacyScrubber matches the tokens back to your local session map and rehydrates the original text instantly in your browser. Q: What file types are supported for local sanitization? A: PrivacyScrubber supports local parsing and sanitization for PDF (.pdf), Word (.docx), and plain text (.txt) files up to 25MB directly in your browser. Q: Is PrivacyScrubber free? A: Yes. The General Profile is free to use with generous character limits and universal PII detection. PRO unlocks all 30 specialized industry profiles, batch file processing, custom regex rules, and offline OCR parsing. TEAMS enables organization-wide encrypted session sharing and team governance.
