Quetext AI Detector checks writing for signs of AI-generated text and plagiarism in one scan. It analyzes writing patterns, perplexity, and burstiness, then shows line-by-line results with a confidence score. Its detection covers writing associated with ChatGPT, GPT-5, Claude, Gemini, and Llama. The free plan allows up to 1,000 words for AI detection and plagiarism checking; paid plans start at 7.99 USD per month, billed annually for AI Detector Only. Other tools in the writing toolkit include paraphrasing, an AI Humanizer and Summarizer, grammar and spell check, and a citation generator. The Chrome extension checks webpages, Google Docs, WordPress, and plain HTML. Its API accepts text or files and returns AI and plagiarism scores, with integrations described for Canvas, Blackboard, and custom portals. Bulk uploads can use Google Drive or OneDrive, and reports can be downloaded or shared as PDFs. Quetext cautions that short phrases can be difficult to assess and that the detector works better with longer, structured text.
Who it is for
