Our Commitment to Teachers

In November of 2022, ChatGPT’s release opened the Pandora's box on massively available AI-generated content.

At GPTZero, we immediately knew the new challenge that AI could pose to information transparency and academic integrity. Within three months, we built the first AI detector with more than 300,000 teachers from 45 states and 30 countries using our tool to detect AI. We now have more than 3 million users and partner with universities and school systems around the world.

We’re evolving to keep up with the latest in AI detection and offer educators more holistic education solutions: writing reports, origin analysis, advanced scan, and interpretability metrics. With teachers, we want to empower you with the guardrails on technology in the classroom to foster originality, encourage critical thinking and prepare your students for the future with AI.

Much will change with AI technology, but our commitment to educators remains steadfast.

Sincerely,

Edward Tian

Founder & CEO, GPTZero
