If you’ve correctly cited all the sources you used, then you do not need to use a plagiarism checker before submitting your paper to your instructor. However, it is very easy to commit plagiarism accidentally, even if you’ve been very careful. To ensure that you didn’t forget to cite anything, you should use a plagiarism checker yourself.
A plagiarism checker works by using advanced database software to scan for matches between your text and existing texts.
To help you decide which checker to use, we conducted in-depth research comparing popular plagiarism checkers to find out which one is best.
