PrivacyScrubber: Zero-Trust PII Masking

What it does

Stop risking data breaches when using AI. PrivacyScrubber acts as an offline local firewall between your data and GenAI models. 🔒 Zero-Trust: 100% browser-side processing. Zero data sent to our servers. ✈️ Airplane Mode Verified: Cut your internet connection and test it. 🔄 Reverse Scrub: Paste AI responses to restore original names & details instantly. 📂 File Support: Sanitizetxt,docx, and PDFs locally. Protect client contracts, code logs, and medical records in one click.

Redact PII from AI prompts and files locally in browser RAM before ChatGPT, Claude, or Gemini. 100% zero-server, GDPR & HIPAA compliant.

Automatically redact and anonymize data like [FINANCIAL_DATA] before sharing with any LLM. The privacy scrubber runs 100% locally in your browser RAM — zero data ever leaves your device. 100% Offline Processing. Supported: .txt, .docx, .xlsx, PDF (3 pages) (Free) & PDF (unlimited), CSV, Batch, OCR (PRO) Redacted in volatile RAM — zero data ever leaves your device. Pre-configured entity detection libraries tailored for each sector (Healthcare, Legal, Finance, DevOps) to sanitize PII in local RAM before AI processing. Select a document or snap a photo above to strip PII instantly. Sanitized locally in volatile RAM. Pre-prompt compliance maintained under GDPR & SOC 2. "Zero-Trust Data…from privacyscrubber.com

  Local Privacy Firewall-blocks PII and secrets before ChatGPT sees themDec 2025 · github.com · ▲111

  OP here. I built this because I recently caught myself almost pasting a block of logs containing AWS keys into Claude. The Problem: I need the reasoning capabilities of cloud models (GPT/Claude/Gemini), but I can't trust myself not to accidentally leak PII or secrets. The Solution: A Chrome extension that acts as a local middleware. It intercepts the prompt and runs a local BERT model (via a Python FastAPI backend) to scrub names, emails, and keys before the request leaves the browser. A few notes up front (to set expectations clearly): Everything runs 100% locally. Regex detection…

  A local-first, reversible PII scrubber for AI workflowsDec 2025 · medium.com · ▲38

  Hi HN, I’m one of the maintainers of Bridge Anonymization. We built this because the existing solutions for translating sensitive user content are insufficient for many of our privacy-concious clients (Governments, Banks, Healthcare, etc.). We couldn't send PII to third-party APIs, but standard redaction destroyed the translation quality. If you scrub "John" to "[PERSON]", the translation engine loses gender context (often defaulting to masculine), which breaks grammatical agreement in languages like French or German. So we built a reversible, local-first pipeline for Node.js/Bun. Here…

  PII Firewall EdgeDec 2025 · pii-firewall-edge-web.vercel.app · ▲5

  Hi HN, I built PII Firewall because I got tired of watching "privacy" APIs secretly pipe user data to cloud AI models. If you're using GPT/Claude to redact PII, you're literally giving the AI your PII. What makes this different: - Zero AI – deterministic regex + 30 checksum validators (Luhn, Verhoeff, Mod 11/97) - Zero storage – processes on Cloudflare edge, no logs, no persistence - 152 PII types – SSN, Aadhaar, 50+ country IDs, 20 API key formats, crypto wallets - Two modes: `/fast` (2-5ms) for structured PII, `/deep` (5-15ms) adds names/addresses via 2000+ name…
