GPTZero is an AI content detection and writing integrity platform designed for educators, institutions, and organizations that need to identify AI-generated text and support responsible writing. It helps teachers, students, publishers, and hiring teams distinguish human writing from content produced by large language models while preserving trust and transparency. Day to day, users paste or upload documents, run scans against leading AI models, and receive percentage-based likelihood scores along with sentence-level highlights that show which sections are likely AI-written. They can also check for plagiarism, review hallucinated or unsupported claims, and generate writing reports that visualize the drafting process or provide video-based human writing verification.
