Sudowrite is a web app that is designed for creating original writing. It allows users to generate unique content by providing writing suggestions. While Sudowrite aims to promote originality, it is possible to make it plagiarize. For example, if you paste in the first paragraph of Harry Potter, Sudowrite will confidently output the second paragraph, as it can find that content in various places on the web, such as book reviews. This feature assumes that users have good intentions.
However, if you start with your own work, Sudowrite will provide you with completely original suggestions. It is important to note that using Sudowrite to plagiarize or engage in any dishonest activities is strictly against their terms of service.
