PII EraserLegal & Compliance
Adopt Legal AI Without Compromising Client Confidentiality
Redact PII from contracts, court filings, and case files — and build LLM-powered legal tools with a real-time PII guardrail that runs entirely within your infrastructure.
The Privilege and Privacy Conflict
The Innovation-Confidentiality Standoff
Law firms and legal departments are racing to adopt GenAI — contract review assistants, legal research copilots, document drafting tools, and agentic due diligence workflows. But the data that makes these tools valuable is also the data that must be protected under attorney-client privilege, professional conduct rules, and data protection regulations.
PII Hiding in Unstructured Legal Text
The hardest PII to protect lives in free text. Case narratives, contract clauses, due diligence memos, free text fields in case management databases, and client correspondence all contain dense personal identifiers — party names, addresses, tax IDs, bank details — interleaved with legal terminology and cross-references that generic NER models and regex-based tools consistently miss.
Compliance Bottlenecks
Attorney-client privilege and client confidentiality requirements frequently prohibit sending documents to external services for processing. Many legal AI projects stall for quarters while compliance, ethics, and IT security teams work through approval.
Built for the Complexity of Real Legal Data
PII Eraser supports the OpenAI chat completion format directly, leading to improved accuracy and sub-second latency via intelligent context.
Legal documents don't just contain personal identifiers. Protect client names, counterparties, deal values and project codenames that create risk even when they aren't classified as PII under privacy regulations.
PII Eraser runs air-gapped inside your VPC or on-prem environment. The container is built with a hardened, minimal dependency stack for easier security review and faster ethics committee approval.
PII Eraser is optimized for legal-domain data across all supported languages and countries, including contracts, court filings, compliance documents, due diligence memos, free text fields in case management systems, and more.
Redacted legal text is only useful if the legal context survives. Redact party names, addresses, and identifiers while preserving legal citations and case numbers that downstream workflows depend on.
PII Eraser automatically handles identifiers in 6 languages and 15 countries, such as German Steuer-IDs and French NIR numbers. No language configuration required. See the full entity list.
Common Workflows
Legal AI Assistants & Agent Workflows
Redact PII from legal documents before feeding them into LLM-powered review tools, summarization engines, or research assistants. PII Eraser's native chat support handles multi-turn Q&A workflows over legal documents — including agentic pipelines and MCP-enabled tool integrations.
Discovery & Cross-Party Document Sharing
Anonymize documents before sharing with opposing counsel, regulators, or auditors during discovery and due diligence. Detect and redact party names, addresses, tax IDs, bank details, and other identifiers — up to 1M+ tokens per request with no accuracy degradation.
Case Management & Document Pipelines
Integrate PII Eraser into your case management software to automatically detect PII in newly ingested text — including free text fields in databases that are a frequent source of unprotected personal data. Flag or redact sensitive data before storage, indexing, or downstream processing.
