PII Privacy Filter

The PII Privacy Filter runs a privacy-specialized model through Apple MLX to detect names, addresses, IDs and 50+ other PII categories — then de-identifies them six ways: mask, redact, fake (via Faker), hash, date-shift or remove. It handles plain text, .docx (formatting preserved) and .pdf (true PyMuPDF redactions).

Because inference is fully on-device, it’s safe for exactly the documents you’d never upload anywhere. A bilingual (EN/ES) desktop app with a clean review workflow before anything is changed.
