GPTZero is a platform designed to identify whether a piece of text was written by a human or an AI model. It analyzes documents, sentences, and words to provide probability scores, supporting the identification of content from models including GPT-4, Gemini, and Claude.
The software is designed for educators, content publishers, recruiters, and cybersecurity professionals. It provides tools beyond basic detection, such as plagiarism checking and authorship verification to help users maintain content integrity.
Users can access the tool via a Chrome extension, Google Docs, or Canvas. There is also an API for those who wish to integrate detection into their own platforms.
Buyers should consider that no AI detector is 100% accurate. The company recommends using the tool as a starting point for conversations rather than a final verdict, especially when assessing student work.
