Ai Pii Guard Local

AI PII Guard is a local-only text scrubber that helps prevent accidental leaks when you paste content into AI chats.

It detects and redacts (best‑effort):

• Secrets/API keys → [SECRET]
• Emails → [EMAIL]
• Phones → [PHONE]
• IBAN → [IBAN]
• Payment cards (Luhn) → [CARD]
• Optional: PESEL (PL)
• Advanced (optional): SSN (US), NINO (UK), NIP/REGON (PL), IPv4, MAC, SWIFT/BIC

Two ways to use it:

1. Popup workflow: paste → scrub → copy
2. Paste Guard (optional): on supported AI sites, the extension checks pasted text and either:
• Calm mode: asks whether to replace with scrubbed text
• Force mode: auto-replaces (undo with Ctrl+Z)

No network requests. No analytics. Everything stays on your device.

Disclaimer: Detection is best‑effort — always review before sharing.
