The Problem

  • PII scattered across documents
  • Multiple data types to identify
  • Risk of missed redactions
  • Volume of documents to process
  • Compliance requirements

How AI Supports This Workflow

Claude identifies PII across documents for redaction. It detects multiple PII types, identifies locations in documents, suggests redaction approach, batch processes document sets, and generates PII reports.

Step-by-Step Workflow

1

Define PII categories

Specify which types of personal information to detect

2

Process documents

Claude scans document set for all PII patterns

3

Review detections

Verify identified PII and check for false positives

4

Apply redactions

Use redaction tools with Claude's detection output

5

Verify completeness

Run final check and generate compliance reports

Tool-specific Steps

Detect and classify PII across this document set for downstream redaction.
Output: detection report with locations, categories, and redaction recommendations.

When to escalate

  • Escalate if low-confidence detections affect high-risk compliance categories.
  • Escalate if source quality limits reliable identification of sensitive identifiers.

Do This Now

  • Choose your tool tab and copy the prompt.
  • Run the workflow and review the top legal risks first.
  • Compare output against your matter facts before sharing.
  • Escalate to attorney review when any escalation check is triggered.
  • Save your final notes and move to the related tutorial for deeper practice.
