What is Polygraf’s Humanized Text Detector?

Simply editing AI-generated content doesn’t make it original human work, and hybrid text is harder to identify.

Our Humanized Text Detector identifies AI-written content that’s been edited by humans, revealing residual AI origins.

  • Detects hybrid content where AI output has been human-edited
  • Highlights residual AI patterns invisible to traditional AI detectors
  • Provides clear probability scores with explainable evidence
  • One-click analysis with transparent and auditable results
  • No data stored or reused; every analysis is private and secure
  • Built for compliance with GDPR, FERPA, CCPA and enterprise audit requirements
