How it began

Luke Sanborn developed the first version of Percent Human over his winter break. Matthew Sahagun joined next, connected by his shared vision for transparency in student work.

Percent Human was launched on January 3rd, 2023, to detect GPT- 3-generated text (months before OpenAI and Turnitin could launch a detector). Since then, the team has led professional development workshops for educators and students and has grown into an incredible group of engineers and researchers.

Additionally, Matt and Luke have worked with over five school districts and countless IT and school administrators to implement a solution in their school systems.

Luke will continue his AI detection journey as a software engineering intern at GPTZero.
