Used by over 10 million teachers and students across more than 100 countries, GPTZero detects AI-generated text across major language models while providing a suite of writing verification tools. This service analyzes content to identify whether text was produced by AI, offering 99% accuracy through a seven-component detection model. Beyond basic detection, it includes Writing Replay for video proof of the writing process, a hallucination detector, plagiarism checking, and grammar verification. Paid plans start at $12.99 per month for Premium (billed annually), which includes 300,000 words monthly, or $24.99 per month for Professional with 500,000 words and batch scanning up to 250 files. A free plan covers basic detection features.

GPTZero serves educators, school administrators, and students managing academic integrity, with 1 million educators currently using this service. It's the official AI detector partner of the American Federation of Teachers and offers an AI Certified Educator program through webinar training. Content creators and organizations requiring content verification also form a core user base, particularly those needing to authenticate authorship or evaluate writing quality. This software accommodates users across skill levels, from individual teachers checking assignments to administrators implementing institution-wide detection policies through learning management systems.

GPTZero integrates directly into existing educational workflows through Canvas and Google Classroom connections, allowing teachers to scan submissions without leaving their grading environment. The Chrome extension highlights AI-generated sections within Google Docs, Gmail, and social media platforms, making verification part of everyday browsing. Professional users can scan entire document batches through the dashboard or connect via API for custom implementations. Multilingual detection supports international teams and institutions, while downloadable reports provide documentation for academic or compliance purposes. Organizations use Zapier integration to build automated verification workflows, and the page-by-page scanning feature helps content teams review longer documents section by section rather than as single blocks.
