GPTZero - a ChatGPT detection tool

GPTZero is a plagiarism tool to review content produced by AI softwares, such as ChatGPT

With the release of ChatGPT, many individuals including students have taken to the AI software to either assist or complete a given task. However, now an app has been released to check for content written by AI. 

Created by Edward Tian in three days, GPTZero uses ChatGPT against itself to detect content produced by AI.

The web app is designed to detect whether a body of text has been written by AI or by a human. Released in January, Tian aimed to create the AI plagiarism tool based on analysis from the research of Princeton Ph.D. candidate Sreejan Kumar and the work of Princeton’s Natural Language Processing Group.

The free application is available for all, especially academicians to review student papers for AI plagiarism. The Terms of Service of the application mention some fees for certain services, with a 30-day free trial for new users that register.

The accuracy of GPTZeros is being contested by many users on the internet, especially since the developer has mentioned that the accuracy may not be 100%.

GPTZero can be used through its site here, where users can paste the text in the box, or upload a file that needs to be reviewed.

The AI program analyzes the randomness of text, known as perplexity, and the uniformity of this randomness within the text, called burstiness. AI is very consistent in its perplexity and burstiness while humans can vary in their writing.

ChatGPT has provided a free access tool for people to misuse the service for academics, and a tool such as GPTZero was necessary to ensure the dependency on AI service doesn't get out of hand.
