How it works

A tiny model. A hard rule set.

Redact pairs a 6-layer multilingual token classifier with a dependency-free deterministic layer. The neural model reads context (names, streets, messy natural-language PII) while checksum-validated rules own the structured fields: emails, URLs, IPs, cards (Luhn), IBANs, SSNs, national IDs for all 24 EU countries, all 27 EU VAT numbers, IMEI, and driving licences.
