🛡️ PII Shield

Anonymize documents before Claude sees them. Restore real data after analysis.

---

PII Shield reads your documents locally, replaces all personal data with placeholders (``, ``, etc.), and — when you want analysis — sends only the anonymized text to an LLM. After analysis, PII Shield restores the original data into the final document — entirely on your machine. **PII never enters the API.**

Document ──> [PII Shield on your machine] ──> anonymized text ──> [LLM analyzes] ──> [PII Shield restores] ──> Result
              John Smith  →                                                  → John Smith
              Acme Corp.  →                                                        → Acme Corp.
