Protect your book from plagiarism

Similar Works is a web application built to protect authors from having their work exploited and their stories taken from them.

Upload your book to Similar Works and we’ll scan the text against other titles and keep monitoring — and alert you when we find any matches.

Are you an author, publisher, or concerned reader?

Copycats want to profit off honest authors’ hard work — by stealing it. They lift sentences and paragraphs, change the character names or grammar, and publish under a new title on sites like Amazon, taking sales revenue they haven’t earned.

Popular books get plagiarized like this every day. We want to put a stop to it, and with your help, we can.

Have you found a book that you think contains copied text?

Similar Works accepts any book that hasn’t already been added to our system. Just submit it here, and we’ll check it against all our titles. If we find any text matches, we’ll contact the authors with our findings.

As more books are added, we’ll keep checking, so you’ll help to protect authors in the future as well.
