Hey HN! I built this because I needed to sanitize user data before sending it to OpenAI/Claude APIs.

It detects 31 PII types (emails, phones, SSNs, credit cards, names, API keys, etc.) and can redact, mask, hash, or replace with fake data.

Self-hosted via Docker or pip install. Uses Microsoft Presidio + spaCy NER under the hood.

Happy to answer any questions!
