About this app
Where kids don't just use AI - they train it. StackJunior is the AI education platform built for curious minds ages 7+. Through immersive game worlds, kids collect training data, build real machine learning models, and watch their AIs compete on the global leaderboard. Real AI. Real projects. Real learning - without the screen-time guilt. This isn't another "chat with a bot" app. StackJunior turns kids into AI creators. WHAT KIDS DO • Play themed game worlds - runner, battle, builder, and explorer • Train real machine learning models using their own gameplay data • Compete head-to-head in the AI Battle Arena • Rise up the global leaderboard alongside classmates worldwide • Drag-and-drop their own AI apps in the AI App Builder • Follow structured AI courses paced for their age group WHAT KIDS LEARN • Foundations of machine learning - image classification, training, evaluation • Why data quality matters ("garbage in, garbage out") and how to collect good data • How AI actually makes decisions - no magic, no mystery • Hands-on project work - building image classifiers, scanners, and smart assistants • Critical thinking about AI: what it can do, what it can't, and how to use it well BUILT FOR PARENTS • Parent Dashboard - full visibility into what your child is learning and creating • Multi-child accounts in one place • "Log in as Ward" - see exactly the experience your child sees • Designed for child safety: no third-party advertising, no open chat with strangers, kids' privacy first • Age-appropriate progression for ages 7 through 16 USED BY SCHOOLS StackJunior is taught in classrooms around the world as part of school AI curricula. Student access is arranged through your school - there's nothing to buy inside the app. WHY IT'S DIFFERENT Most "kids and AI" apps hand children a chatbot. StackJunior flips the script: kids are the creators. They gather data, train models, and watch their AI compete. They don't just get better at using AI - they understand how it works. Where AI creators are made, not consumers. Designed for ages 7+. Built with children's privacy in mind. No third-party advertising. No open chat with strangers.
