GPTZero

GPTZero is an app developed by Edward Tian, a computer science student with a minor in journalism, which is designed to distinguish between essays written by humans and those written by the AI-powered language model known as ChatGPT.

His motivation for creating the application was to combat AI plagiarism, which has become more prevalent with the release of ChatGPT. OpenAI, the company responsible for ChatGPT, has also committed to preventing its misuse and has been working on a way to add an imperceptible signal to GPT-generated text that can be used to identify its source.

Hugging Face, an open-source AI community, has also put out a tool to detect if text was created by GPT-2, the AI model used to make ChatGPT. A professor in South Carolina used this tool to catch a student submitting AI-written work.
