PII & Secret Redactor
Redact PII and secrets from text before it reaches an LLM. Checksum-verified cards, IBANs and routing numbers, SSN range rules, API keys, and reversible placeholders you can restore after the model responds.
Send the question, not the customer's data
Strip personal data and credentials out of text before it goes to a model, a log or a ticket, then put the originals back in the answer.
What it detects
- Verified, not just matched: credit cards (Luhn, brand identified), IBANs (mod-97), US routing numbers (ABA checksum), SSNs (invalid ranges rejected). Order numbers and random digit strings are left alone.
- Contact and identity: emails, phone numbers (US and international), labelled dates of birth, US street addresses, IPv4 and IPv6.
- Secrets: Anthropic, OpenAI, AWS, GitHub, Stripe, Slack and Google keys, JWTs, private keys, database URLs with credentials.
Tools
detect_pii: findings with type, position and a masked preview. Never echoes full values.redact_text: placeholder (stable tokens like<EMAIL_1>, same value gives the same token), mask, salted hash, or remove.restore_text: swap placeholders back to the originals in the model's response, using the mapping you keep.list_detectors: exactly what is and is not covered.
Be clear about the limits
Pattern and checksum based. It does not detect personal names or free-form addresses in other formats, so it reduces exposure but is not a compliance guarantee for HIPAA, GDPR or PCI. Input is processed in memory and never stored or logged.
