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.

What We Redact

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

Employee PII including SSNs, personnel numbers, and performance data redacted from HR documents

Financial records with account numbers, transaction details, and salary information anonymized

Medical records containing patient names, provider details, and diagnosis information 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

Hypothetical Case Study by Justee

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. All employee names, email addresses, SSN references, health details, and financial information were replaced with structured placeholders. The AI categorization tool then sorted emails by relevance and privilege indicators without accessing any actual employee personal data.

Discovery Email: Before vs. After Redaction

Why it matters: Employee names, email addresses, SSN, employee ID, insurance carrier, and home address are all replaced. The email content about benefits enrollment issues and the general topic remain intact for relevance categorization by AI.

No credit card required

Discovery document review is where AI delivers the most value 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, Justee offers plans designed for higher-volume processing. Each document typically completes in under two 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 all 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.
