Polygraf AI Detector
What Polygraf AI Detector is
Polygraf AI Detector identifies whether content was created or altered by AI. It reports AI-versus-human probability scores, can indicate which models may have generated the content, and provides confidence scores with explainable evidence. One-click verification is intended to produce transparent, auditable results. The consumer detector lists content from ChatGPT, Gemini, Claude, and other models, and is available on the web and as a Chrome extension. File uploads and API access are available. Polygraf also lists integrations with ChatGPT/OpenAI, Microsoft Copilot, Google Gemini, Anthropic Claude, and AWS Bedrock, though some cloud-dependent integrations require internet access and are unavailable in air-gapped deployments. Related Data Provenance tools include AI highlighting, copyright and plagiarism detection, humanized text detection, writing analysis, and synthetic voice detection. The company says analyses are private and data is not stored or reused. Plans include Free, Standard at $9.95 a month, and Premium at $49.95 a month. The free plan includes 2.5K monthly tokens, approximately 2K words.
