GPTZero

Dubbed the world’s number one AI detector, GPTZero boasts over a million users as we speak.

As its name says, the tool is made to identify content generated by AI models — including ChatGPT, GPT3, GPT4, Bard, and others — to bring transparency and to enable users to differentiate between human- and AI-generated content. GPTZero even provides a Chrome extension called Origin for seamless use.

For educators, there’s GPTZeroX – a suite of tools that includes a plagiarism scoring system which provides a comprehensive score indicating how much of a document is AI-written. It also highlights sentences in a document that are detected to be written by an AI. Moreover, GPTZeroX supports batch uploads so that educators can upload multiple files at once.

For broader organizational use, GPTZero offers an API that can be integrated into existing apps and services. It has been adopted by academic institutions such as the University of California, Berkeley, Duke University, and the National University of Singapore, as well as organizations like Product Hunt and Translate.com.
