ABOUT GPTZERO

GPTZero's tiers are priced on words scanned per month, which is the right unit for an institution and an awkward one for a casual user. The word figures recorded here are from the annual-billing view; a promotional discount code was active at the time of checking, so the 9.09 and 17.49 USD figures shown on the page are promotional rather than list. No AI detector, this one included, is accurate enough to be treated as proof on its own.

OVERVIEW

Who is it for?
Teachers, universities, editors and publishers who need a defensible read on whether a submitted document was AI-written.
Problem
AI-written text is not distinguishable by eye, and an accusation of academic misconduct needs evidence rather than a hunch.
Solution
GPTZero scores documents for AI-generated writing with basic and advanced scan modes, highlights the specific passages it flags, supports multiple languages and exports reports. The free tier covers 10000 words monthly; Premium is 12.99 USD monthly-equivalent billed annually for 300000 words.
What makes it unique
Detection sold explicitly for institutional workflows - batch file scanning, page-by-page analysis, exportable reports and LMS integration - rather than as a single-box web checker.
