Quetext is a writing integrity platform combining a DeepSearch plagiarism checker, AI content detector, grammar checker, summarizer, humanizer, and citation generator for students and professionals.
About
Quetext is a writing integrity platform that helps students, teachers, and professionals verify that their text is original and human-written. It addresses two related problems: unintentional plagiarism in academic and professional writing, and the growing need to identify content produced by AI models such as ChatGPT and Gemini.
The service is built around Quetext's proprietary DeepSearch technology, which compares submitted text against billions of internet sources using contextual analysis and word-placement algorithms. On top of that core, Quetext layers a suite of writing tools — an AI detector with sentence-level confidence scores, a grammar and spell checker, an AI summarizer, an AI humanizer, the AITutorMe paraphrasing tool, and a citation generator. Quetext Software LLC operates the platform, which the company says has served more than 10 million users. It is available through a web app, browser extensions for Chrome, Firefox, and Edge, an MCP integration for AI assistants, and a RESTful developer API.

Who It's For
Quetext is aimed at students who want to confirm their assignments are original and correctly cited before submitting, and at teachers and professors who need to check large batches of work — bulk uploads and an remarks tool support classroom-scale review. Content marketers and copywriters use it to verify blog posts and campaign copy for originality before publishing.
