AI-written text detector by Edward Tian
Each check below is a fact we could verify from public sources. Unknown checks are excluded from the calculation instead of counting as a negative, and the score is pulled toward the midpoint when coverage is low — that is what data coverage reports.

GPTZero is an AI text detection tool created to identify whether a given text was written by a human or generated by AI (like ChatGPT). It analyzes text perplexity and burstiness — measures of randomness and variation — to judge the likelihood of AI authorship. For example, if the text has low complexity and uniform sentences, it's more likely AI-generated:contentReference[oaicite:8]{index=8}. Initially developed by Edward Tian to help teachers catch AI-generated essays, GPTZero has evolved with more advanced models and an API for organizations. Users can input text and GPTZero returns an evaluation indicating if the writing appears to be AI-generated or human.
