Sudowrite AI has been trained on a large corpus of narrative text and generates the next word(s) based on previous input. If you're using original text as your input, you will get original content out of Sudowrite. However, Sudowrite can be forced to output content that is not original by giving it verbatim input text from famous sources like Harry Potter. It is recommended to use Sudowrite with original writing for original output and to double check the final result with plagiarism checkers.
