Princeton University senior Edward Tian has developed GPTZero, an app to detect whether text is written by the AI chatbot ChatGPT, addressing concerns about AI plagiarism in academia. The app uses “perplexity” and “burstiness” indicators to distinguish human-written text from AI-generated content. While not foolproof, the app aims to bring transparency to AI and promote responsible adoption of AI technologies. Other efforts to curb AI plagiarism include OpenAI’s plan to watermark GPT-generated text, and Hugging Face’s tool to detect AI-written content. The New York City education department has blocked access to ChatGPT in schools due to concerns about its impact on learning.
