ABOUT HUMAN THINKING (THE COMPANY) AND CHATTUTOR (THE PRODUCT) Human Thinking builds tools that keep people thinking when they work with AI. Our motto is Human Thinking. AI Assisted. ChatTutor is our product for education. It lets a teacher decide how the AI behaves in their own course, grounded in their own material and their own didactics, and lets them follow the students' conversations and step in where it makes sense. Practically that means custom PDF parsing for equation-heavy STEM material, an escalation path to the human teacher, and an annotation system that carries good answers forward from semester to semester. We are a small team out of Nørrebro, Copenhagen, working with universities and educational institutions, and a published study in Educational Psychology Review found students learned more with ChatTutor than with ChatGPT.
