PrivacyScrubber is a browser-based, 100% local PII redaction tool that detects names, emails, phone numbers, API keys and other identifiers with regex and replaces them with typed tokens (e.g., [NAME_1]) so you can safely paste anonymized text into LLMs like ChatGPT, Claude, or Gemini and then locally restore originals by "un-masking" the AI's tokenized response; because all processing, OCR (PRO) and token mapping happen in-memory with zero network calls (Airplane Mode verifiable), it enables privacy-preserving AI workflows that help meet HIPAA/GDPR/SOC2 requirements and prevents accidental leaks of sensitive data while offering PRO features like batch processing and custom redaction rules.
