PII / PHI Redaction

Detect and mask sensitive data before it ever reaches a model or a log.

How it’s engineered
  • Sensitive data leakage is #2 on the OWASP LLM Top 10. The fix is to redact before text reaches the model, the logs, or a third party, not after.
  • Detection combines strict patterns (emails, phones, card numbers with a Luhn check, SSNs, MRNs) with lightweight name and address heuristics, all running on your device.
  • In production this is a deterministic pre-processing gate with per-type policies (mask, hash, or drop) and an audit trail, sitting in front of every LLM call. It is cheap, fast, and testable.
  • 100% in-browser: the text you paste never leaves your device, which is the whole point of a privacy gate.
