Polygraf AI Detector
Austin, Texas, USA
What it is
Polygraf AI Detector identifies whether content was created or changed by AI, reporting AI-versus-human probability scores with confidence indicators and explainable evidence. It can also identify AI models that may have generated content, and offers one-click verification with auditable results. The consumer detector lists ChatGPT, Gemini, Claude, and other models, and is available on the web and as a Chrome extension. File uploads and API access are listed. Polygraf also offers Data Provenance tools for 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. It says analyses are private and data is not stored or reused. The service has a free plan, along with Standard at $9.95 a month and Premium at $49.95 a month. The listed supported-language count is one. Some cloud-dependent integrations require internet connectivity and do not work in air-gapped deployments. Polygraf was founded in 2021 and is headquartered in Austin, Texas.
