Teachers now have a tool to help them detect AI-generated essays written by ChatGPT, a popular AI chatbot. The tool, named GPTZero, was created by 22-year-old Princeton computer science student Edward Tian, who developed it in response to the rise of AI plagiarism.
OpenAI, the developer of ChatGPT, is also taking steps to prevent AI plagiarism and forgery, such as working on a way to watermark GPT-generated text with an "unnoticeable secret signal" to identify its source. The New York City education department has also blocked access to ChatGPT on school networks and devices.
Despite this, Tian is not opposed to the use of AI tools like ChatGPT, and believes that they should be used responsibly and ethically. GPTZero uses two indicators to determine whether text is written by a human or AI - perplexity, which measures the complexity of the text, and burstiness, which compares the variation of sentences.
