StackJunior: AI for Kids
AI Education for Curious Kids
Free · Designed for iPad. Not verified for macOS.
Where kids don't just use AI — they train it. Play game worlds, train real machine learning models, battle on global leaderboards. Now on iPhone & iPad!
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.
