SchoolAI Reaches 1 Million Classrooms

SchoolAI, founded by former teacher Caleb Hicks, has rapidly scaled to 1 million classrooms in over 80 countries, leveraging OpenAI’s GPT-4o, GPT-4.1, image generation, and text-to-speech to create safe, teacher-guided AI learning environments. Its architecture includes Dot, a lesson-building assistant, and Sidekick, a student-facing tutor that adapts to learning styles while keeping teachers fully informed through observable logs and guardrails. The system utilizes smart model routing to strike a balance between accuracy and cost, ensuring AI coaches students rather than providing answers. By adhering to OpenAI’s stack, SchoolAI scaled quickly while reducing costs, saving teachers over 10 hours per week and enabling earlier interventions. The platform is reshaping education by enhancing engagement, personalization, and equity while supporting both classrooms and home learning.
