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. Related Data Provenance tools include AI highlighting, copyright and plagiarism detection, humanized text detection, writing analysis, and synthetic voice detection; the company says these tools are included in all plans. Polygraf says analyses are private and data is not stored or reused. Listed plans are Free at free, Standard at $9.95 a month, and Premium at $49.95 a month.
