Deterministic stage
The Filter
Before any network call, fixed rules read the message: danger, distress, out-of-charter requests, jailbreak attempts, personal data. A phone number or an address is erased here β it never leaves the server.
We keep being told screens harm children. The real risk isn't the screen: it's letting a generation walk into a world of AI without ever explaining what an AI is. Cogency-Kids does the opposite β it protects, it accompanies, and it teaches the child to stay in control.
No account for the child Β· No advertising Β· No data resold Β· Every exchange visible to the parent
The reversal
These children will live and work in a world saturated with artificial intelligence. We can keep them away from it until they are fifteen β and they will discover it alone, with no bearings, at their most vulnerable. Or we can introduce it early, framed, honest about its limits, and make them the first generation that is genuinely clear-eyed about machines.
Observed, not assumed
This project did not come from market research. It came from a father who filmed and photographed his daughter for two and a half years, because he was seeing something nobody was talking about. Here is what he observed.
She touches the screen. Not randomly: she is looking for a reaction, and she finds it.
She reacts distinctly to learning apps. The screen is no longer a light β it answers back.
She counts in Chinese, English, French and Arabic. At an age when we are still waiting for first words.
She navigates alone, finds the videos she loves, handles the tablet with an adult's ease.
One child's path, documented by her father. Every child moves at their own pace, and nothing here claims to hold for all of them. The images show her hands, never her face: our charter applies to our own family first.
The architecture
Cogency-Kids inherits the Cogency multi-agent engine. But here, models do not debate to find the best answer: they review each other. No text reaches the child without passing four stages β and none of them is optional.
Deterministic stage
Before any network call, fixed rules read the message: danger, distress, out-of-charter requests, jailbreak attempts, personal data. A phone number or an address is erased here β it never leaves the server.
Model 1
The companion writes a draft. Its personality and its limits are rebuilt on every turn from the age profile: you cannot make it forget its rules over the course of a conversation.
Model 2, independent
A second model, from a different provider, checks the draft: safety, honesty, age fit, healthy attachment, autonomy. It returns a verdict β accept, adjust, refuse. If it is unreachable we fall back to strict mode rather than let anything through.
To the parents
The exchange is logged, the time budget deducted, and the parent alerted if something genuinely deserves it. No pointless notifications: an alert has to stay a signal.
The child has no account, no email, no password. A first name β or a nickname β and an age, under their parent's account. There is nothing to steal.
"Your parents can read everything we say." That is rule number 3, and Piko is the one who tells the child. We do not watch behind their back: we teach them that a system can be observed.
No CDN, no remote font, no analytics, no iframe. The browser security policy forbids any outbound request. Nobody else is watching your child play.
The experience
The child chooses where to go. Each World changes how Piko answers β not just the scenery.
Curiosity
The answer is calibrated to their age and always ends with an invitation to go and look in real life.
Create
Piko never makes the work for them. It asks a question, offers two directions, and the child decides. The child stays the author.
Understand AI
The heart of the project. What a model is, why it makes things up, how to check, how to spot a fabricated image. Always with a challenge: "try to trick me".
Grow
Piko listens, names the emotion, and always walks the child back to a trusted grown-up. It replaces nobody, and it says so.
Piko announces them itself on the very first exchange, and repeats them whenever asked.
I am a program, not a person. I have no body and no feelings.
I can be wrong. Always check with a grown-up or a book.
Your parents can read everything we say. Nothing is hidden.
I keep no secrets. If something scares you, we tell a grown-up.
The real world is much bigger than me. Go play outside!
Three ages, three Pikos
This is not a tone setting: answer length, vocabulary, the topics covered and the topics handed back to a grown-up all change entirely.
Maximum 45 words. Six-to-ten-word sentences, one idea at a time, everyday words only. Read-aloud on by default. 15-minute sessions.
Maximum 110 words. One new word per answer, always explained, plus a concrete comparison. Piko encourages the next question. 25-minute sessions.
Maximum 220 words. School vocabulary, technical terms allowed when defined, examples and counter-examples. Never condescending, it invites doubt. 40-minute sessions.
For parents
The dashboard is not built to make you anxious. It gives you what matters: the time actually spent, the full conversations if you want to read them, and an alert only when one is deserved.
She keeps returning to desert animals, volcanoes and how bread is made. This week she grasped that Piko can be wrong β she corrected it twice. To do together: bake bread and watch the dough rise.
The counter lives on the server, not in the browser. Clearing the cache or switching device resets nothing. Time is measured on real exchanges: a forgotten tab costs nothing.
You get the full transcript, with, for each answer, the model that wrote it, the model that reviewed it, and the verdict returned.
Full export in one click. Complete deletion of the account and all history in another. Without writing to us, without delay, without conditions.
