How can data you choose to use help solve a problem that matters to your community?
AI for a Better Community — Codex Challenge invites young people and educators to turn ideas into AI applications that help others. Start with something you’d like to improve in your school, family, neighborhood, or community. Then use data you choose to bring your idea to life—creating something useful for the people around you and contributing to the public good.

Program Timeline
Ready for submission
Youth builders
Teen teams can build practical tools for themselves, friends, families, schools, or communities. Begin with the needs of people you know. Curiosity and care matter as much as technical experience.
Educators and mentors
Teachers and other educators can create applications to support teaching, learning, or professional practice—and help young builders approach AI responsibly.

The challenge is designed for young people and educators who want to use AI to create something useful for their school, family, neighborhood, or community. Youth teams can participate with support from teachers, mentors, or other adult facilitators. Educators can also develop their own projects.
Information about final age, location, and registration requirements will be provided with the official application instructions.
We suggest teams of 2–5 students so everyone can contribute to designing, building, and testing the application. Individuals or other team sizes can also develop ideas; official team-size requirements for submission and showcase participation will be published by the organizers.
Artificial intelligence (AI) refers to computer systems that perform tasks often associated with human intelligence, such as recognizing patterns, understanding language, making predictions, or generating content. This includes generative AI, machine learning, natural language processing, and computer vision.
Your application should use AI in a meaningful way. Explain what the AI does, why it helps solve the problem, and where human judgment is still important. Learn more with Day of AI’s “What Is Artificial Intelligence?” curriculum ↗.
Yes. Start with the Codex 101 builder introduction and use these learning resources to explore possible approaches, user needs, and responsible AI design:
Your team can build an AI application for a social, environmental, educational, health, or economic need—or another issue important to your community. Explore Climate, Economic Prosperity, Health, Learning, and Other for example directions. These are ideas to inspire projects, not restrictions on what you can build.
The proposed judging approach emphasizes community impact, purposeful use of AI, responsible data practices, feasibility of the working prototype, and human-centered design. Teams should show whom the project helps, demonstrate what they built, and explain choices and limitations. See the Judging Criteria section for the full description. Final criteria will be confirmed by organizers.
After the December 20, 2026 submission deadline, organizers plan to review projects and select teams to share their work at the January 22–23, 2027 Community Showcase. Details of the review stages, selection numbers, and notification process will be communicated by organizers.
Prepare a short demo video, a prototype link, and a brief explanation of the problem, intended users, data, AI functionality, and responsible design choices. The submission deadline is December 20, 2026.
Selected teams will have an opportunity to share their applications and lessons learned with peers, educators, researchers, and partners during the Community Showcase on January 22–23, 2027.
We're looking for thoughtful, useful solutions. These suggested judging dimensions combine the current Codex Challenge's focus on execution and responsibility with MIT Solve's emphasis on human-centered impact. The final rubric is subject to organizer approval.
