About Paper Rater

PaperRater.com is a free resource, developed and maintained by linguistics professionals and graduate students. PaperRater.com is used by schools and universities in over 46 countries to help students improve their writing.

PaperRater.com combines the power of natural language processing (NLP), artificial intelligence (AI), machine learning, information retrieval (IR), computational linguistics, data mining, and advanced pattern matching (APM). We offer the most powerful writing tool available on the internet today.

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.

Vocabulary Builder

Besides our flagship product, we also offer a premiere Vocabulary Builder tool designed to help students learn proper usage of more sophisticated words. Learning a new word with just a definition was always a frustrating experience when growing up, so we solve this problem by integrating example sentences to show the correct usage of each word in a real context.
