Best Free Plagiarism Checking Sites
The best free online plagiarism checking sites for educators.
Plagiarism is an age-old problem.
The word, derived from the Latin plagiarius (“kidnapper”), dates back to 17th-century English. Much earlier than that, in the first century, the Roman poet Martial used “plagiarius” to castigate another poet whom he accused of appropriating his words.
How We Test: Each site included here was tested using passages of 150-200 words on these topics: plagiarism (Wikipedia), George Washington (Wikipedia), and Romeo and Juliet (Cliffsnotes). Sites that didn’t recognize the copied text were deemed unreliable and therefore excluded.
In our modern world, however, the ability of students to find and copy others’ work is greater than ever before. While there are a number of in-depth and effective paid solutions that allow educators to verify the originality of student work, there are only a few free solutions that are worth trying.
We have compiled the best free online plagiarism checkers. Several share a very similar interface and ad profile, suggesting a common parent company. Regardless, all were able to reliably identify the plagiarized passages and identify a source.
