Quetext

Quetext is one of the most-used plagiarism detectors by students, teachers and content creators to verify text originality before publishing or submitting. It has a good balance of accuracy and price in the mid-tier of the category.

Quetext is a plagiarism detection tool that analyzes text by comparing it with billions of web pages, books and academic articles to identify any matches with already-published content. It works simply: you paste text or upload a file, and the tool generates a report highlighting portions similar or identical to existing sources, indicating the source and match percentage. Quetext's DeepSearch technology examines text at multiple levels, looking not just for literal matches but also for paraphrases and similar constructions. Beyond traditional plagiarism detection, Quetext includes an AI-generated text detector, which identifies passages likely written by models like ChatGPT. Bibliographic citations can be generated directly from the platform. It's used mainly in academic contexts — students checking their papers before submission — and by content marketers who want to ensure their copywriters' texts are original.

For students, teachers, journalists and content marketers who want to verify text originality and detect any plagiarism or AI-generated content before publishing or submitting.

Quetext has a free plan with 500 words per month of analysis, sufficient for brief occasional checks. The Pro plan starts at $9.99 per month and includes analysis of a high number of monthly words, AI detection, citation generation and advanced features. Plans with specific terms are available for students and institutions. Annual billing reduces the monthly cost.
