About PII Masker for ChatGPT & Claude – MOM Shield

MOM Shield automatically detects, redacts and masks sensitive data (PII) — names, emails, phone numbers, addresses, IBANs, API keys and passwords — directly in your browser, before you send any prompt, file, PDF, screenshot or scanned document to ChatGPT, Claude, Gemini, Grok or Perplexity. Everything runs 100% locally on your device — nothing is uploaded — so you can use AI productively and stay GDPR-compliant.
