What is GPTZero
GPTZero was launched by Princeton University students as anAI content detection tool, which identifies and analyzes whether input text was created by AI, distinguishing between human-written and AI-generated content. The tool supports AI content detection at the sentence, paragraph, and document levels, determining the source of text by analyzing its "perplexity" (i.e., the complexity and unpredictability of the text) and "burstiness" (i.e., the degree of variation in sentence structure and length). Human writing is more complex and varied, while AI-generated text is relatively regular and uniform. GPTZero is applied in fields such as education, publishing, and content moderation, helping users identify AI-generated content and maintain academic integrity and information authenticity.
