PaperRater - 2026 Pricing, Features, Reviews & Alternatives

PaperRater is an online proofreading software designed to help businesses leverage artificial intelligence (AI) technology to identify grammatical mistakes, detect plagiarism, and automatically score essays. Teachers can upload files in multiple formats including DOC, ODT, TXT, RTF, and DOCX to the platform and use the vocabulary builder to learn new words and their meanings in different contexts.

PaperRater uses machine learning (ML) and natural language processing (NLP) capabilities, which let writers gain insights into the syntax or structure of their text, receive feedback about errors, and enhance readability across papers, memos, letters, and more. The plagiarism checker compares the submitted files to multiple documents, books, journals, research papers, articles, and other sources across the web, ensuring originality of the content. The software also allows educators to receive students' assignments via email and view a summary of all submissions in a tabular form.

PaperRater analyzes submitted documents based on various modules such as sentence beginnings, readability, vocabulary usage, sentence length or variability, passive voice, and more. Students can also view statistics about plagiarism, grammar, or spelling mistakes and download results in PDF format according to requirements.
