PII Redaction for Legal Discovery Documents and AI Use

Backed by Microsoft For Startups
U.S. and England & Wales law
AES-256 Encryption
Free to start, no credit card

PII redaction for legal discovery documents protects parties, witnesses, and third parties before AI review. Discovery produces massive volumes of documents containing personal data, and Justee removes it automatically so litigation teams can use AI for document review and analysis safely.

Free and no sign-up required.

Key Takeaways

Discovery documents contain PII for numerous individuals including parties, witnesses, employees, and third parties

Justee processes discovery materials and replaces 30+ PII entity types with structured placeholders automatically

All discovery documents are encrypted in transit (TLS 1.2+) and at rest (AES-256) with immediate deletion after redaction

AI-assisted discovery review becomes safer when documents are redacted before submission to any AI platform

Electronic discovery has transformed litigation practice, generating document volumes that can reach millions of pages in complex cases. AI-assisted document review has emerged as a practical necessity for managing these volumes, with technology-assisted review (TAR) and predictive coding becoming standard tools. However, the efficiency gains of AI review create data protection tensions when discovery documents contain sensitive personal information. Production sets may include emails with personal details, financial records, employment files, medical records, and communications involving dozens or hundreds of individuals who may not be parties to the case. Submitting these materials to AI review platforms without PII redaction exposes all of that personal information to external systems. Justee addresses this challenge by providing automated PII redaction that can process discovery documents efficiently, detecting the broad range of entity types found in typical production sets and replacing each with structured placeholders that maintain the document relationships AI review tools need to function effectively. 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

Email sender and recipient names, addresses, and contact details replaced across correspondence

Employee PII including names, SSNs, and contact details redacted from HR documents

Financial records with account and routing numbers anonymized

Patient names and provider identifiers in medical records stripped

Third-party PII found in forwarded emails, attachments, and referenced documents removed

Risks of Sharing Unredacted Documents

Discovery sets may contain PII for hundreds of non-party individuals who deserve data protection

AI review platforms process large document volumes, magnifying the exposure from any single breach

Privileged documents mixed into discovery sets require extra protection before any AI processing

Production metadata may contain identifying information beyond what appears in document text

Cross-border discovery documents may trigger international data protection regulations

How It Works

1
Upload Discovery Documents

Upload emails, memos, or other discovery materials in PDF or DOCX format.

2
Broad PII Detection

Justee scans for employee names, email addresses, SSNs, account numbers, and more than 30 entity types in all. Policy numbers and employee IDs are not detected, so remove them yourself.

3
Review Before AI Review

Check the redacted documents and their typed placeholders before submitting them to your AI review platform.

4
Submit to AI Review Tool

Use the redacted documents with any TAR, predictive coding, or AI categorization platform safely.

Illustrative Example

A class action defense team received a production of 5,000 employee emails and needed to use AI to categorize them by relevance and identify privileged communications. The emails contained employee names, personal email addresses, phone numbers, discussions of health conditions, references to SSNs in benefits enrollment threads, salary complaints, and personal financial discussions between coworkers.

Issue Found: The 5,000 emails contained PII for approximately 300 unique employees, including health information shared casually in workplace communications, personal financial details, and SSN references from benefits enrollment, none of which needed to reach the AI review platform.

Resolution: The defense team processed the email production through Justee before AI review. Employee names, email addresses, SSN references, and home addresses were replaced with structured placeholders, and reviewers removed health details by hand. The AI categorization tool then sorted emails by relevance and privilege indicators without seeing the redacted employee personal data.

Discovery Email: Before vs. After Redaction

Why it matters: Names, email addresses, the SSN, the insurer, and the home address are replaced. The employee ID and the health detail are not redacted, so remove them yourself before AI review.

A note from Justee

Discovery review is one of the places AI helps most in litigation, but it is also where the most personal data is at risk. Redacting before AI review is not a luxury; it is a necessity for responsible e-discovery practice.

Frequently Asked Questions

The free tier processes individual documents efficiently. For large discovery sets, paid plans raise the monthly redaction limit. Each document typically completes in minutes.

Yes. Justee's typed placeholders produce clean text that TAR and AI review platforms can process effectively. The redacted documents maintain their categorization value while protecting personal data.

Privileged documents in discovery sets benefit especially from PII redaction before AI review. Justee removes detected identifying information that could contribute to privilege waiver if exposed to external AI platforms.

Justee detects email-specific identifiers including sender/recipient addresses, CC/BCC references, email signatures with contact details, and PII mentioned within email body text and subject lines.

Ideally, redact before any AI processing, including relevance review. If that is not practical for very large sets, consider a phased approach where initial AI categorization uses redacted samples, with comprehensive redaction before detailed AI analysis.

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.
