Signal Galaxy
Spot the AI around you
Find which everyday apps decide for you, see how feeds learn from your taps, and trace any post back to its source.
Explore the galaxy
of AI
Short, hands-on missions that show you how artificial intelligence really works — from machine learning to the ethics behind it.
Free to start · Built for ages 11–14 · Safe for schools
Three galaxies, then First Contact
Every mission teaches a skill you can actually use. The galaxy names are the map — the skills are the point.
Pattern Galaxy
Teach a machine yourself
Code a rover with exact steps, then train a rock-sorting robot with your own examples — and watch it learn from data.
Mirror Galaxy
Judge what AI tells you
Catch unfair training data and answers that sound sure but are wrong — with a checking routine you practice until it sticks.
First Contact
Earn your first real AI chat
Your first open conversation with an AI isn't given — you unlock it by showing you can question what it says.
Two more expeditions are on the horizon: Forge Galaxy (building with AI) and Compass Galaxy (good calls).
Learn by doing
01 · LEARN
Bite-sized lessons
Two-minute missions break big ideas into small, clear steps you can actually finish.
02 · PRACTICE
Try it yourself
Tap, build, and experiment. You learn AI by doing it, not by reading about it.
03 · PROGRESS
Watch your progress build
XP shows how far you've flown. Streaks show you kept coming back. Every milestone is yours alone — nobody here is ranked against anybody.
Choices we made on purpose
Research-backed for real
Every lesson is built on peer-reviewed learning science — with the receipts to prove it. See the research
No leaderboards, on purpose
Research says competition hurts learning at this age. So every milestone is personal — your streak, your pace, your progress.
Safety is the curriculum
Kids earn AI access by learning to use it safely first. Safety isn't a disclaimer here — it's the thing we teach.
