PlagAware vs Quetext AI Detector

PlagAware is a plagiarism search engine for educational institutions, businesses, and individuals. Its FullScan technology checks submitted text against more than 70 billion online documents and user-provided comparison texts, while text monitoring can flag potential copying or duplication on texts and web pages. An AI detector looks for stereotypical language associated with systems such as ChatGPT, Copilot, Gemini, and LLaMA; PlagAware says it does not send data to those external providers. Reports can be edited interactively, downloaded as PDFs, and shared through permanent links. Users can paste text, upload TXT, RTF, HTML, DOC, DOCX, ODT, and PDF files, or submit through the API. The web application works in supported modern browsers without workstation installation and offers integrations for Moodle, SharePoint, Joomla, WordPress, and Blogger. It accepts texts up to 750,000 characters, files up to 15 MB, and up to 50 parallel uploads. A significant coverage limit is that it does not access non-public sources such as paid scientific journal articles or paid portal content. Plans include free use, subscriptions, and prepaid credits; Subscription Light is €2.99/month with a six-month minimum term.

Quetext AI Detector analyzes writing for signs of AI-generated text, including text associated with ChatGPT, GPT-5, Claude, Gemini, and Llama. It examines writing patterns, perplexity, and burstiness, then presents line-by-line results with a confidence score. The same scan checks for plagiarism. Quetext cautions that short phrases can be difficult to assess and that longer, structured text works better.

The free plan includes AI detection and plagiarism checks for up to 1,000 words, plus Summarizer and Humanizer limits of 2,000 words. 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 plagiarism and AI scores, with integrations described for Canvas, Blackboard, and custom portals. Reports can be downloaded or shared as PDFs. Quetext’s privacy policy says submitted content and usage data may be used for AI training and quality processes by default; it offers an opt-out for future inclusion of identifiable personal data.
