Polygraf AI Detector vs UncovAI AI Detector Extension

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. The free plan includes 2.5K monthly tokens, approximately 2K words; Standard includes 150K monthly tokens, approximately 135K words, and Premium includes 1M monthly tokens, approximately 900K words.

UncovAI AI Detector Extension checks text, images, and links on web pages for AI-generated content, manipulated images, and phishing risks. Users can scan an item with one click and see the result in the browser without leaving the page. The extension is available for Google Chrome and Mozilla Firefox, with the same core detection features in both. UncovAI describes its text detector as distinguishing human writing from text generated by models such as ChatGPT or Gemini. Image checks are intended to identify generative AI and deepfake or manipulated images; link scans flag dangerous or scam sites before a click. Checks are on demand, and UncovAI says it does not continuously log browsing activity. Its privacy policy says it may collect account, contact, transaction, device, usage, and location data, and may share personal information with service providers where needed. Plans include Freebie at €0/Month, Plus at €9.99/Month, and Pro at €19.99/month after the first month free. Zoom and Teams audio detection and WhatsApp and Telegram scam or deepfake detection are also offered.
