What is Quetext?
Quetext is a writing-integrity tool that pairs plagiarism checking with AI content detection. Its search engine, which the company calls DeepSearch, compares submitted text against web pages, academic papers and published works, then shows results with colour-coded highlighting that separates exact matches from near matches, a side-by-side snippet viewer and an overall score. The AI Detector analyses text sentence by sentence and attaches a confidence score to each line. Around these sit further tools: a grammar and spell checker, an AI summariser with selectable length and output style, the AITutorMe paraphrasing tool, an AI humaniser with several tone options and a citation generator. Text can also be checked through a Chrome extension or programmatically via a REST API, and paid tiers allow bulk file uploads. There is a Free plan plus Essential and Professional subscriptions, the latter priced by word volume for teams and schools.
