With the advent of artificial intelligence (AI) tools such as ChatGPT, and the increasing availability of fake information on the Internet, many schools are concerned that students are using AI to commit plagiarism.
Edward Tian, a 22-year-old Princeton University student studying computer science and journalism, has developed an application called "GPTZero" that identifies whether the text is generated by AI to stop students from abusing ChatGPT.
The tool identifies traces of AI use by analyzing the "perplexity" and "burstiness" of text, and assumes that if both indicators are low, the text is probably generated by AI. It is reported that GPTZero achieves 99% accuracy for manual text recognition and 85% accuracy for AI text.
In addition, Edward is now launching a new project called Origin, which aims to "save journalism" by distinguishing between AI-generated disinformation and the facts reported by the media, and has received US$3.5 million in funding led by venture capital firm Uncork Capital and startup accelerator Neo.
GPTZero, which now employs 10 people, was launched in January 2023. Over 30,000 people tried out the tool within a week of its launch, crashing the servers. Since its launch, 1.2 million people have registered with the tool.
