Text similarity that runs too high against existing sources, even unintentionally (a badly paraphrased citation, a passage left outside quotation marks), can be enough to have a paper or a dissertation rejected.
These tools compare the text against vast databases of academic publications and student work, and report a similarity score against the sources concerned before official submission.

Frequently asked questions
What is the best tool for detecting plagiarism before submitting a scientific paper?
Turnitin is the reference used by most journals and universities, with access to a very large database of academic publications. Compilatio is a French alternative, widely used by French-speaking institutions.
Does a high similarity score always mean plagiarism?
