Workflow

How Piixie processes government documents.

From ingestion to anonymized output, every step happens on your machine. No data ever crosses a network boundary.

1. Load sensitive document

Drop classified memos, FOIA requests, citizen records, personnel files, or inter-agency reports into Piixie. PDF, DOCX, spreadsheets, and images are all supported.

2. Detect PII and markers

The local LLM identifies citizen PII, employee data, classification markings, CUI designations, and sensitive identifiers across structured and unstructured text.

3. Anonymize

Choose redaction, token replacement, or synthetic data generation. Names are replaced, SSNs masked, and classification markers flagged for review.

4. Export safe copy

Anonymized document saved locally with full audit log documenting every detected entity. The original is never modified.

Compliance

Regulatory frameworks Piixie addresses.

Local processing eliminates entire categories of compliance risk across every framework that governs government data.

  • Piixie operates fully offline in air-gapped environments, meeting the strictest security requirements for classified document processing.
  • FOIA response preparation is automated: citizen PII, employee names, and exemption-covered content are detected and redacted before public release.
  • No data leaves the local machine at any point, satisfying Privacy Act requirements for records containing individually identifiable information.
  • CUI handling requirements are met by processing sensitive data locally without third-party exposure.
  • Classification markings and handling instructions are detected to prevent accidental disclosure during document sharing.
  • Audit logs provide evidence of proper redaction procedures for Inspector General reviews and compliance audits.
