AI Explorers turns coding and AI into a hands-on adventure for curious kids. Guide Pix through puzzles, train tiny machine learning models, write real Python, and build your own levels while learning the ideas behind modern computing. Designed for playful learning, AI Explorers helps children practice sequencing, loops, variables, if statements, while loops, debugging, sorting, searching, shortest paths, and the basics of artificial intelligence. Each concept is introduced through interactive lessons and then reinforced through games. Pix can read missions aloud, and young explorers can steer the robot with their voice. What kids can do: • Solve coding puzzles with arrows, loops, gems, and goals • Type real Python in Code Lab and watch Pix run it • Train Pix: draw examples and watch real machine learning happen on the device • Explore algorithms like sorting, binary search, and shortest path • Build logic circuits, pattern puzzles, and custom levels in Maker mode • Turn prompts into pictures in Prompt Safari (on devices with Apple Intelligence) • Ask Pix questions about coding, robots, and AI (on devices with Apple Intelligence, switched on by a grown-up) • Unlock concept cards in a learning journal and customize Pix with earned rewards • Keep a daily puzzle streak, with a Pix widget on the Home Screen AI Explorers is built for kids who learn best by trying, testing, fixing, and trying again. There are no dry lectures: every lesson is visual, interactive, and friendly. Mistakes become part of the learning loop, especially in debugging and AI training missions where kids see why examples, clues, and corrections matter. Available in English, Spanish, French, German, and Portuguese. For grown-ups: • No ads, no tracking, no analytics. All AI runs on the device, and nothing your child makes is sent to us. • Purchases, settings, sharing, and web links are behind a grown-up check. • The Grown-Up Zone shows progress and lets you set screen-time and Ask Pix limits. • The first games of every world are free. AI Explorers Premium, a monthly or yearly auto-renewing subscription, unlocks every game, lesson, and lab. Parents and educators can use AI Explorers as a gentle introduction to computer science, Python, STEM thinking, and responsible AI concepts. Learn with Pix. Build the path. Run the code. Teach the AI. Terms of Use (EULA): https://sudoswisshub.github.io/AIExplorersLegal/terms.html Privacy Policy: https://sudoswisshub.github.io/AIExplorersLegal/privacy.html
