Hi HN, I built this because I kept pasting sensitive info into ChatGPT without thinking client names, financial details, API keys.

PrivacyShield detects 15+ types of PII as you type, masks them with placeholders like [PERSON_A] before sending, then unmasks the AI's response so you see your real data back.

Everything runs locally. No servers, no data collection. AES-256 encrypted mappings that auto-expire.

This is v0.1 — would love feedback. Bugs: support@piiblock.com or GitHub issues.
