Yes. The anonym.legal Chrome Extension automatically detects and anonymizes PII before it reaches ChatGPT, Claude, Gemini, Copilot, or any AI tool. Your original data never leaves your browser.

Yes. Upload PDF, Word, Excel, or text files for batch anonymization. The platform processes 5,000+ documents per batch with full audit trail. OCR support detects PII in scanned documents.

48 languages with native NLP models: 24 spaCy models, 6 Stanza models, and 18 Transformer models. Each language has region-specific entity detection (e.g., Steuer-ID for German, NIR for French, Codice Fiscale for Italian).

Yes. The REST API and MCP Server allow you to anonymize PII in your data pipeline with 3 lines of code. Sub-200ms latency. Python and Node.js SDKs available. Bearer token authentication.

The EU AI Act (full applicability August 2, 2026) requires GPAI providers to document training data handling. Anonymizing PII before AI training ensures Article 10 compliance. anonym.legal provides audit evidence for each anonymization.

The Problem with Current Solutions

$

Enterprise Tools Cost $30K-$100K/yr

Nightfall, Google DLP, and Private AI price out 95% of organizations. anonym.legal starts at $0/month with 200 free tokens.

βš™

Open-Source Takes 30-80 Hours

Raw Presidio requires custom recognizers, NLP models, and deployment. anonym.legal deploys 1,066 recognizers pre-configured across 48 languages.

⚠

Inconsistent Redaction = #1 Compliance Failure

Single-engine tools miss 40-60% of non-English PII. Our 3-layer NLP hybrid (spaCy + Stanza + XLM-RoBERTa) catches what others miss.

6 Anonymization Methods

Choose the right method for your compliance requirement. Each method is available across all 7 platforms.

Replace

Substitute PII with realistic fake values. "John Smith" becomes "Max Mueller". Maintains data utility for testing and analytics.

GDPR Art. 89

Mask

Partially obscure values: "DE12 3456 7890 1234" becomes "DE** **** **** 1234". Preserves format while hiding sensitive digits.

PCI DSS

Redact

Complete removal β€” replace with [REDACTED] or custom placeholder. Required for FOIA responses and court document production.

FOIA / e-Discovery

Hash (SHA-256/512)

One-way cryptographic hash. Irreversible. Enables de-duplicated analytics without re-identification risk.

HIPAA Safe Harbor

Encrypt (AES-256-GCM)

Reversible anonymization with RSA-4096 key exchange. Only authorized parties can decrypt. Multi-party key sharing supported.

Reversible

Custom

Define your own anonymization logic: regex patterns, lookup tables, format-preserving encryption. 108 presets included.

Frequently Asked Questions

PII anonymization is the process of removing or transforming personally identifiable information β€” names, addresses, ID numbers, phone numbers β€” so individuals cannot be re-identified. anonym.legal supports 285+ entity types across 48 languages using 6 methods: replace, mask, redact, hash, encrypt, and custom patterns.

Anonymization irreversibly removes identifying data β€” GDPR no longer applies to truly anonymous data. Pseudonymization replaces identifiers with tokens that can be reversed with a key β€” GDPR still applies but with relaxed obligations under Art. 4(5). anonym.legal supports both approaches.

Yes. The free tier includes 200 tokens per month with access to all 7 platforms, all 285+ entity types, and all 48 languages. No credit card required. Paid plans start at $3/month for 1,000 tokens.

anonym.legal uses a hybrid NLP engine combining spaCy (24 languages), Stanza (6 languages), and XLM-RoBERTa transformers (18 languages) with ID validation algorithms. The test suite scores 419/419 (100%) across 13 test milestones.

Yes. Data masking is one of the 6 supported anonymization methods. You can mask PII with configurable characters (e.g., J*** D** for names, ****-****-****-1234 for card numbers) while preserving data format and length for downstream processing.

Yes. anonym.legal detects entity types required by GDPR (EU), CCPA/CPRA (California), HIPAA (healthcare), LGPD (Brazil), APPI (Japan), PIPA (Korea), KVKK (Turkey), PDPA (Singapore), and 40+ other privacy regulations worldwide.
