Publisher Description

PaperRater is an online document checker tool that analyzes any input files in real time 24/7. This includes grammar checking, spelling checking, proofreading online and also a possibility to detect plagiarism.

Plagiarism Detection

Plagiarism is a growing concern for both teachers and students as papers are sometimes copied in whole by unscrupulous students, or portions of text are not properly cited by writers that are ignorant or careless. We offer an Originality Score that indicates the percentage of your paper that is original.

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.

Feedback and Writing Instruction

In addition to flagging grammar and spelling errors, our automated proofreader includes various modules that present analyses of the text and comparison with other students at the same education level. Some of the modules include:
- Vocabulary usage
- Sentence length and variability
- Phrases to avoid
- Passive voice detection
- Readability statistics
- Analysis of sentence beginnings

Automated Scoring

Our development team has experience building state-of-the-art automated essay scoring systems, and this expertise has been incorporated into our Auto Grader module. You will receive a score that reflects a rough idea of what you may receive from your teacher.

Our free service is not meant merely to "upsell", but is a full-fledged product used and loved by 99.9% of our users from over 140+ countries. A core part of our mission is offering writing tools that are accessible so you can be certain that we will always offer our free service.
