GPTZero: AI Detector and Human Writing Verifier

GPTZero is used and trusted by millions of educators and institutions and recognized by The New York Times, Wall Street Journal, and Washington Post.

The GPTZero Chrome extension allows you to scan text to check if it was written by an AI or a human. You can use the extension on any website, either highlighting and right-clicking text or copy-pasting text into the Origin text box.

On Google Docs, the extension allows writers to prove they created their own work. We combine AI detection with the powerful ability to replay your document edit history and share a report verifying the human involvement during writing.
