Polygraf AI Detector
Polygraf AI Detector identifies whether content was created or manipulated by AI. It reports AI-versus-human probability scores, confidence information, and explainable evidence, and can identify which models may have generated content. The consumer page lists detection for ChatGPT, Gemini, Claude, and other models. One-click verification produces results described as transparent and auditable. The product is available on the web and as a Chrome extension, with file uploads and API access. Polygraf lists integrations with ChatGPT/OpenAI, Microsoft Copilot, Google Gemini, Anthropic Claude, and AWS Bedrock; some cloud-dependent integrations require internet access and do not work in air-gapped deployments.
