This was the middle and high school Data & AI track hackathon of the 2026 AI Donghaeng Project.
Students from schools in different regions came to Hanyang University on September 19.
In the morning they framed a topic through AI ethics, and in the afternoon each team spent two and a half hours building an app.
The day opened with a welcome and a career talk, moved through topic planning and building,
and ended with a gallery walk of each other's apps and a closing ceremony.
Data and AI at work, and where it can lead
Choosing a problem through fairness, safety and accountability
Exploring AI models and building the app on Jitda · test run
Publishing the apps and looking around each other's work
Team feedback · judges' remarks
The theme was AI ethics. Each team took one lens — fairness, safety or accountability —
and turned a problem close to home into an app: a bad smell in the neighborhood, walking home at night, disaster alerts, school lunch waste.
At the same time, in a separate room, the accompanying teachers took a training session on teaching AI ethics.
We picked twelve of the 39 student projects built on Jitda that day and published to the gallery.

What the AI Donghaeng Project decided was the track theme and the participating schools.
Jitda took on the venue setup and laptops, the timetable, the build environment and on-site mentoring on the day, and publishing to the gallery.
Students from different regions and grades moved on the same timetable. Gathering once meant 39 teams delivered work on the same day, on the same theme.
While the students planned and built their apps, the teachers who came with them took a training session on teaching AI ethics and a mini hackathon in a separate room.
Students only had to open a browser. Laptop specs and install permissions were nothing the venue had to deal with.
Each app went up to the gallery the moment it was built, and other teams opened it and left comments. The links still work today.
While the timer on the front screen counted down, planning sheets and laptops spread across every table.
Forty minutes in the afternoon went to a gallery walk of each other's apps.
