GPTZero AI Detection is a web-based AI content detection tool launched in January 2023 that uses a proprietary deep learning model (currently Model 3.7b, released August 2025) to determine whether a given text was written by a human or generated by an AI. The system analyzes text at the document, paragraph, and sentence level and returns probability scores together with a three-class label (HUMAN_ONLY / MIXED / AI_ONLY). GPTZero detects output from all major LLMs and offers a web dashboard, a REST API, and integrations for education and enterprise workflows. In June 2026, GPTZero was acquired by Superhuman (Grammarly).
