Free to start, no credit card

Justee helps you anonymize legal documents for AI processing by replacing names, SSNs, bank and card numbers, and other identifying details with structured placeholders. True document anonymization goes beyond simple name removal. Justee covers 30+ entity types so the AI works with placeholders instead of real identities.

Free and no sign-up required.

Key Takeaways

Effective anonymization requires removing all identifying information, not just names, from legal documents

Justee anonymizes 30+ PII entity types using typed sequential placeholders that preserve document relationships

Documents are encrypted in transit (TLS 1.2+) and at rest (AES-256) and files are deleted immediately after processing

Anonymized documents maintain full legal content and structure for productive AI analysis and processing

Document anonymization in the legal context requires a comprehensive approach that addresses every potential identifier in a document. Simply removing names is insufficient, addresses, phone numbers, email addresses, Social Security numbers, financial account details, employer names, and even combinations of seemingly innocuous details can be used to re-identify individuals. True anonymization requires systematic detection and replacement of all identifying elements, creating a document where no combination of remaining data points can be linked back to a real person or organization. Justee works toward this with entity detection covering over 30 PII categories, combined with a replacement strategy that uses typed, sequential placeholders. These placeholders serve a dual purpose: they prevent re-identification while preserving the relational structure of the document. When [PERSON_1] appears in multiple locations, the AI understands it refers to the same entity throughout, enabling meaningful analysis of the document relationships and legal content while the detected identities stay hidden. According to Justee (justee.ai), personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort; if redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain), so always review the output before relying on it.

What We Redact

Anonymization of personal identifiers: names, SSNs, dates of birth, and government IDs

Location anonymization covering home addresses, business addresses, and geographic references

Financial anonymization removing account numbers, routing numbers, and tax IDs

Professional identifier anonymization for bar numbers, medical licenses, and NPI numbers

Relational preservation through typed sequential placeholders maintaining document context for AI

Risks of Sharing Unredacted Documents

Partial anonymization, removing names but leaving addresses, can still allow re-identification

Unique combinations of non-PII details (job title + city + date) can identify individuals

AI platforms may correlate partially anonymized data with other sources to re-identify subjects

Manual anonymization often leaves some identifiable traces due to human oversight

Insufficiently anonymized documents create a false sense of security while still exposing data

How It Works

1
Upload Document for Anonymization

Upload your legal document in PDF or DOCX format for anonymization.

2
Multi-Category PII Detection

Justee scans for 30+ categories: names, government IDs, bank and card numbers, addresses, professional IDs, and more.

3
Verify Anonymization Quality

Check the anonymized document: each detected entity is replaced with a typed placeholder.

4
Process with AI Safely

Download the anonymous version and submit it to any AI tool, after checking that identifying data is removed.

Illustrative Example

An immigration law firm wanted to use AI to analyze visa petition patterns across 60 client files to improve their success rate predictions. The visa petitions contained beneficiary names, passport numbers, alien registration numbers, employer sponsor names, job titles with specific salary offers, home country addresses, and U.S. addresses where beneficiaries would reside.

Issue Found: Immigration files present extreme re-identification risk because the combination of nationality, job title, employer, and salary can uniquely identify individuals even without names, making comprehensive anonymization essential, not optional.

Resolution: The firm processed all 60 visa petitions through Justee. Names, passport numbers, employer details, and addresses were replaced with placeholders, and staff removed A-numbers and salary offers by hand. The AI then analyzed petition strength patterns based on job categories and filing types without seeing the redacted beneficiary identities.

H-1B Visa Petition: Before vs. After Anonymization

Why it matters: The employer, EIN, beneficiary name, passport number, and work address are replaced. The A-number and salary are not redacted, so remove the A-number yourself before sharing. The visa type and job title stay for analysis.

A note from Justee

Anonymization is not a spectrum. It either works or it does not. A document with the name removed but the SSN intact is not anonymized. Only comprehensive, multi-category PII removal achieves true anonymization.

Frequently Asked Questions

Anonymization aims to make it impossible to link the document to any real individual. Redaction is the removal of specific information. Effective anonymization requires comprehensive redaction of all identifying information, which Justee works toward with its 30+ entity type detection.

Absolutely. Justee's typed, sequential placeholders preserve the relational structure of the document. AI tools can analyze clause patterns, legal arguments, and document structure effectively without needing real identities.

Partly. Justee detects passport numbers, names, dates of birth, addresses, and employer names in immigration documents. It has no dedicated detector for A-numbers or USCIS receipt numbers, so check those and remove them if needed.

Download the redacted file and read it for any remaining identifying details, such as unusual ID numbers or descriptive facts. No automated system is perfect, and PII detection is best-effort.

Justee performs true anonymization by replacing PII with generic placeholders. There is no key or mapping stored that would allow de-anonymization. The original data is not recoverable from the anonymized document.

Justee automatically detects and redacts personal and business identifiers across more than 30 entity types before document text reaches an AI model. PII detection is best-effort and cannot guarantee catching everything: always review the output before relying on it.

Yes. Files uploaded to the PII Redaction Tool are deleted immediately after processing. Personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort). If redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain. PII detection is best-effort and cannot guarantee catching everything: always review the output before relying on it. Your content is never used to train AI models.
