What is GPTZero?
GPTZero serves as a specialized platform designed to distinguish between human-written and AI-generated text. Launched in early 2023, it has grown to support over 10 million users globally, providing a robust suite of tools to ensure academic integrity and content authenticity. The platform utilizes a proprietary multi-step approach involving seven different components to analyze text for patterns such as perplexity and burstiness.
What is ZeroGPT?
ZeroGPT is a web-based utility designed to distinguish between human-written and AI-generated text. It functions as a specialized plagiarism checker for artificial intelligence, scanning documents to determine the probability that content originated from a large language model. The tool employs various algorithms and APIs rooted in AI detection research to provide a detailed probability score.
