Meet GPTZero

GPTZero helps educators, writers, and editors assess whether a document contains AI-generated text. Users can paste writing into the website or upload a file, then review an overall assessment and highlights showing passages that may need closer attention. The service analyzes writing from a range of language models and can identify documents that combine human and AI text.

Alongside detection, GPTZero offers plagiarism checks, grammar feedback, and Writing Replay, which records the writing process in Google Docs so readers can review how a document developed. A Chrome extension brings checks into browser workflows, while classroom integrations and an API support institutional use. Detection scores are estimates intended to support human review, rather than establish authorship conclusively.
