Most plagiarism checkers are only able to detect “ direct plagiarism”, or instances where the sentences are exactly the same as in the original source. Therefore, these plagiarism checkers are not very accurate, as they miss a lot of plagiarism. Many free plagiarism checkers only check your paper against websites – not against books, journals or papers previously submitted by other students.

Plagiarism checkers work by using advanced database software to scan for matches between your text and existing texts. The accuracy is determined by two factors: the algorithm (which recognizes the plagiarism) and the size of the database (with which your document is compared). Many free plagiarism checkers fail to detect all plagiarism or falsely flag text as plagiarism. Per our in-depth research, Scribbr is the most accurate plagiarism checker. The accuracy depends on the plagiarism checker you use.
