A lightweight, production-ready PII sanitizer built specifically for LLM pipelines. Detects and redacts emails, phone numbers, SSNs, credit cards, API keys, JWTs, AWS credentials, and more before prompts reach any model API. Supports bidirectional sanitization (strip before, restore after) and multi-turn session vaults. Zero cloud calls. GDPR & HIPAA ready.
