What PaperRater is

PaperRater is a web-based writing analysis tool whose grammar checker finds spelling, grammar, and punctuation mistakes and suggests corrections. It provides feedback as you work, with explanations intended to help improve writing skills. You can enter text by typing, pasting, or uploading it, then copy or export the corrected version. Review suggestions in one batch by accepting them all, or consider each individually and accept or reject it. PaperRater says the checker supports grammar review in a variety of languages and English dialects at no additional cost, and that it can handle any type of written content. The service also describes itself as checking plagiarism and other aspects of writing. Its automated proofreading uses machine learning and natural language processing to analyze text and generate advice; PaperRater says professional linguists train and monitor its grammar algorithms. The grammar checker page states that PaperRater does not store users’ data or writing. The Free plan costs nothing and allows up to 5 pages per submission, 50 submissions per month, and 10 plagiarism checks per month.
