Using someone else’s text without attribution is plagiarism, whether you meant to do it or not.
Unintentional plagiarism of even a sentence or two can have serious consequences.
While other sites may charge to check plagiarism, it has always been part of our mission to offer services that are accessible to everyone, regardless of income.
For users that demand greater speed and accuracy, we do offer a premium service that allows longer submissions as well.
Our online plagiarism checker compares your text to over 16 billion web pages and academic papers stored in Pro Quest’s databases.
When part of your text matches something written online or in a database, you’ll get a plagiarism alert.
Our free plagiarism check will tell you whether or not your text contains duplicate content.
Our Premium plagiarism check highlights passages that require citations and gives you the resources you need to properly credit your sources.
Our free online plagiarism checker compares your submitted text to over 10 billion documents on the Internet and in print.
Because we do NOT check against previous submissions to Paper Rater, submitting your paper to our service will NOT cause it to get incorrectly flagged as plagiarized if your teacher checks it here later.
