What PaperRater is

PaperRater is a web writing-analysis tool whose grammar checker identifies spelling, grammar, and punctuation mistakes and suggests corrections. It provides real-time feedback with explanations, and users can type, paste, or upload content before copying or exporting the corrected text. Suggestions may be accepted together or reviewed individually and accepted or rejected. The checker says it supports a variety of languages and English dialects at no additional cost and can handle any type of written content. PaperRater describes its proofreading as using machine learning and natural language processing, with algorithms trained and monitored by professional linguists. The service also describes plagiarism checking and other writing analysis. Its grammar-checker page states that it does not store users’ data or writing. The Free plan costs nothing, allowing five pages per submission, 50 submissions monthly, and 10 plagiarism checks monthly.
