Show HN: PrivacyShield – Mask your PII before it reaches ChatGPT/Claude

https://www.piiblock.com
1•BuddhikaR•1h ago
Hi HN, I built this because I kept pasting client data and API keys into ChatGPT without thinking.

It detects 15+ types of PII as you type, masks them with placeholders like [PERSON_A] before sending, then unmasks the AI's response. Everything runs locally — no servers, no data collection, zero network requests. You can verify in DevTools.

Built as a solo project using Claude Code.

Chrome Web Store: https://chromewebstore.google.com/detail/privacyshield/nklgh...

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