About Paper Rater
PaperRater.com is a free resource that utilizes Artificial Intelligence to help students write better. Our technology combines Natural Language Processing, Machine Learning, Information Retrieval, Computational Linguistics, and Data Mining to produce the most powerful automated proofreading tool available on the Internet today. PaperRater.com is used by schools and universities in over 46 countries to help students improve their writing and check for plagiarism.
As part of the development process, we put together a team of computational linguists and subject matter experts to develop a core Natural Language Processing (NLP) engine using statistical and rules-based NLP to extract language features from essays and robustly translate that into statistical models. We hope to showcase some of our technology at a later date.
What makes us different?
We’ve tried out similar websites and found them to be out of touch with most writers’ needs. We found false-positive rates as high as 50% on grammar detection. As the Hippocratic Oath encourages medical doctors to “first do no harm”, we wanted to create tools that do not muddy the waters in the process of assisting with the craft of writing. These same websites acquire hefty payments for the use of their services, while our goal has always been to provide tools that are universally accessible. By ‘accessible’, we mean that our tools are free and not hidden behind signups, logins, and trial offers.
In addition to automated proofreading, we offer free plagiarism detection that utilizes the massive indexes of the major search engines.
