Examples

See how PolicyDiff represents different types of structural and legal changes using our rule-based engine.

Intent Logic: Negation Shift

Detecting when negation words (e.g., "not", "never") are removed from sensitive clauses, fundamentally changing the legal intent.

  "risk_level": "CRITICAL",
  "changes": [
    {
      "section": "Data Monetization",

        { "value": " sell your PII.", "removed": false }
      ]
    }
