Quetext is an online writing-integrity platform built around its DeepSearch™ engine, combining a plagiarism checker, AI content detector, grammar checker, summarizer, humanizer, citation generator and paraphrasing assistant in one dashboard. It is used by students, teachers, copywriters and content teams to confirm that a piece of writing is original, human-written and properly sourced before it is submitted or published.
Quetext's proprietary engine compares submitted text against billions of indexed web pages and published works, returning color-coded match confidence so genuine copying stands out from coincidental phrasing.
Past submissions are scored line by line for signs of machine generation, with confidence levels that help you edit the passages most likely to be flagged.
A suite of helpers covers grammar and spelling correction, instant summarization with selectable length, tone-based rewriting with the AI humanizer, and AITutorMe paraphrasing for restating ideas in your own words.
Generate formatted references and in-text citations quickly, with a citation assistant that keeps sources consistent across a paper or article.
