GPTZero

GPTZero is an AI text detection tool that identifies whether content was written by humans or generated by large language models like GPT or Claude. It’s widely used by educators and institutions to ensure writing authenticity.

Overview of GPTZero

Developed by Princeton student Edward Tian, GPTZero uses linguistic markers such as perplexity (how predictable text is) and burstiness (variation in sentence length) to differentiate human and AI writing. It’s trained on diverse datasets, allowing it to recognize subtle patterns unique to AI-generated text. The platform provides detailed confidence scores, highlighting which sentences are likely AI-written. GPTZero integrates with educational systems and offers a Chrome extension for quick scanning. It’s trusted by universities, journalists, and editors to validate originality and authorship.
