What Quetext AI Detector is
Quetext AI Detector analyzes writing for signs of AI-generated text and displays line-by-line results with a confidence score. It examines writing patterns, perplexity, and burstiness, and can check for AI writing and plagiarism in the same scan. The detector covers text associated with ChatGPT, GPT-5, Claude, Gemini, and Llama. The free plan includes up to 1,000 words for AI detection and plagiarism checking, plus up to 2,000 words for Summarizer and Humanizer. AI Detector Only is listed at $7.99 a month, billed annually, with 50,000 words per month, reports, and API access. The Chrome extension checks webpages, Google Docs, WordPress, and plain HTML. Its API accepts text or files and returns plagiarism and AI scores, with integrations described for Canvas, Blackboard, and custom portals. Users can import bulk files from Google Drive or OneDrive and download or share PDF reports. Quetext says short phrases can be difficult to assess and longer, structured writing works better. Its privacy policy says submitted content and usage data may be used for AI training, evaluation, and quality assurance by default.
