anonym.legal – Detect and remove PII from text, files, and AI chats in 48 languages

Summary: anonym.legal identifies and anonymizes over 285 personal data entity types across 48 languages using hybrid detection methods. It supports six anonymization techniques and integrates with multiple platforms, ensuring AI tools never access real personal data while maintaining compliance with GDPR, HIPAA, and the EU AI Act.

What it does

anonym.legal detects PII using regex, checksum validation, and spaCy NER, then applies reversible encryption, hashing, masking, redaction, or replacement to anonymize data. It intercepts AI chat inputs via a Chrome Extension to anonymize PII before sending and de-anonymizes AI responses locally, preventing real data exposure.

Who it's for

It is designed for compliance teams, organizations, and individuals needing to use AI tools like ChatGPT or Claude without exposing sensitive customer data.

Why it matters

It solves the problem of securely using AI with sensitive data by ensuring personal information never leaves the user's control, enabling privacy compliance without costly or complex enterprise solutions.
