Quetext AI Detector
What it is
Quetext AI Detector analyzes text for signs of AI-generated writing and shows line-by-line results with a confidence score. It examines writing patterns, perplexity, and burstiness, and checks for AI text and plagiarism in the same scan. The detector covers text associated with ChatGPT, GPT-5, Claude, Gemini, and Llama. Its 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 costs $7.99 a month, billed annually, and includes 50,000 words per month, reports, and API access. The Chrome extension checks webpages, Google Docs, WordPress, and plain HTML. The API accepts text or files and returns AI and plagiarism scores; integrations are described for Canvas, Blackboard, and custom portals. Bulk uploads can import files from Google Drive or OneDrive, and reports can be downloaded or shared as PDFs. Quetext says short phrases can be difficult to assess and longer, structured text works better. Its privacy policy says submitted content and usage data may be used for AI training, evaluation, and quality assurance by default, with an opt-out for future inclusion of identifiable personal data.
