Online text content paraphrases detection

Unique content is a valuable resource nowadays, especially in some fields where plagiarism could lead to serious problems. Therefore plagiarism detection becomes very important and this service is proposed rather often, usually even providing links to documents or web pages that were used. Unfortunately most of services work only with direct plagiarism when some parts or the whole content were copied fully or with slight modifications, and unable to detect cases when text was seriously reworked.

Paraphrases detection feature In GroupDocs Rewriter is an easy-to-use and versatile online service to estimate the probability that your text was rewritten. Its advanced AI algorithms can analyze texts and detect paraphrases in seconds. The API tries to understand the meaning of the entire text and find unusual patterns that could be a signal of paraphrasing usage, rather than just comparing random parts of the text with the collection of documents. While the background process is very complex and resource-intensive, you do not have to worry about formulas, machine learning, and load – our cloud services do all the work by providing you with a REST API to interact with them.

This free online application checks for paraphrasing of your text content written in English. It does not limit you to any specific format – you can copy the text from anywhere and immediately get the result in one click.
