GPTZero

GPTZero offers a browser AI detector along with advanced scans, plagiarism tools, and a writing-replay workflow in Google Docs. The public page permits a limited text scan and points to paid plans for higher usage and institutional features. Its detector output is probabilistic, not a proof of authorship. Even a strong result can be wrong on edited, multilingual, or formulaic writing. An educator or publisher should preserve the underlying document history, compare sources, and allow an author to explain the work. Test the product on known examples from your own field before creating a policy around its scores.
