Privilege

Detect privileged content

Changed on

Analyzes text or vault documents for legal privilege review. Detects attorney-client privilege, work product doctrine, and common interest privilege.

Returns structured review flags with confidence scores and policy-friendly rationale suitable for discovery workflows and privilege logs. This endpoint is an AI-assisted triage tool and does not replace attorney judgment.

Size Limit: Maximum 200,000 characters (larger documents rejected).

Permissions: Requires chat permission. When using document_id, also requires vault permission.

Note: When analyzing vault documents, results are automatically stored in the document's privilege_analysis metadata field.
