for Kids
Create secret codes by designing hidden messages, breaking mysterious ciphers, and protecting important information from prying eyes everywhere.
Create secret codes by designing hidden messages, breaking mysterious ciphers, and protecting important information from prying eyes everywhere.
Science-backed, quest-based cryptography activities where young creators explore, build, and bring their ideas to life.
Conversation starters, prompts, and parenting tips to support cryptography at home — without turning into a tutor.
AI Learning Coaches. Three ways of thinking. Kids pick the one that fits the cryptography moment they're in — or switch between them as a project grows.
Each coach answers from a different angle. Kids talk to them by voice, ask real questions, and discover — through the conversation — what kind of thinking clicks for them.
Inspires imagination. Helps kids dream up ideas, make creative leaps, and see possibilities that aren't obvious yet.
Goes deep. Breaks problems down, explains how things actually work, and thinks through the mechanics step by step.
Asks the questions kids haven't thought to ask themselves. Slows things down, pulls out insight, helps kids hear their own thinking.
