Originality Inspector is a Generative Pretrained Transformer (GPT) focused on detecting and reporting plagiarism. Built on top of ChatGPT, it offers advanced content analysis by evaluating the originality of a provided text input. Once activated, the Originality Inspector solicits the user to paste the text that needs to be assessed for originality. This tool can analyze multiple types of narratives ranging from essays, articles, reports, and other forms of written documents. The Originality Inspector then scrutinizes the input and responds with an analysis regarding the uniqueness of the content, identifying and highlighting any duplicates or similitudes with existing content. Carefully designed prompt starters such as 'Check this essay for plagiarism' or 'Assess this document's uniqueness' guide users to engage effectively with the tool and achieve precise results. The use of this GPT can be especially useful for educators, students, writers, and anyone else interested in verifying the originality of a written piece. It requires ChatGPT Plus for optimal functionality.
