DeepSearch™ Illustration

DeepSearch Technology

The standard in plagiarism detection by teachers, students, and professionals

Contextual analysis

DeepSearch™ goes beyond simple word matching; taking into account the surrounding context and the statistical likelihood of each word and phrase.

Fuzzy matching

Our algorithms use state-of-the-art natural language processing to detect "fuzzy" matches, where several words have been changed in an attempt to disguise plagiarism.

Conditional scoring

Fuzzy scoring calculates a conditional score, meaning that we not only factor your DeepSearch™ total score, but each match is also weighted individually in the context of the whole.

Not all plagiarism checkers are created equal

Our proprietary technology helps us detect similarities in a way that only Quetext does.


Custom built with state-of-the-art machine learning & grammatical analysis techniques.
