Grammar and Spelling Checker
Our service incorporates the most accurate grammar and spelling correction software available today. It is a patented, cloud-based system developed through several years of research that identifies errors contextually using machine learning and statistical models. Consider the following sentence:
Upon leaving the grocery I realized that I has left my wallet on the counter. I havent done that since.The two egregious errors are bolded for emphasis. When these sentences are run through the most popular open source grammar checker (to the right), no errors are detected.
Contrast this with PaperRater below, and it's easy to see why accuracy matters in grammar checking.
Real-Time, Real EasyWhile other services take minutes to give results, our automated proofreader runs 24/7 generating results in seconds. We do all this without requiring signups or logins so that there are no obstacles in your way. Did we also mention that this service is free?
