The interactive learning system
Lessons, exercises and progress in a single app. Piko is there too, picking up where the last session left off.
For ages 3 to 12
The AI that grows with them,
The AI that grows with them,
never instead of them.
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 — it protects, it accompanies, and it teaches the child to stay in control.

Learning at home, from 3 to 12
We are opening Cogency-Kids to full learning, online and at home. A kit arrives at your door, the programme follows your child's age — and you are not a spectator: you learn beside them.
What arrives at your home
A desk at their height
A steady work surface at the right height, with somewhere to put things away. A child writing on the dining table writes badly, and not for long.
A chair you can sit in for an hour
Firm seat, a back that genuinely supports, adjustable height. Comfort is not a luxury at this age: it decides how long attention lasts.
Something to write, draw and handle
Notebooks, pencils sized for small hands, a slate, counting material. The hand learns what a screen alone cannot teach.
A programme that follows the age
3 – 5 years
First bearings
Language, sounds, shapes, numbers up to ten. Much play, little screen, sessions of fifteen minutes.
6 – 8 years
Reading, writing, counting
Reading settles, handwriting forms, arithmetic becomes sure. A second language begins — by ear before it is written.
9 – 12 years
Understanding and reasoning
The core subjects take shape: languages, mathematics, science, history and geography. The child also learns to search, to check, and to doubt.
You are not behind your child — you are beside them
Every session offers a moment to do together: a question to ask, an experiment to run, a text to read in turns. Ten minutes is enough. That is where learning becomes a relationship rather than surveillance.
Clear bearings, and an alert only when one is deserved
You see what is moving and what is stuck: time actually spent, what has been grasped, what keeps coming back without being understood. When a signal repeats — a subject slipping, unusual tiredness, discouragement — you are told before it settles in.
None of these alerts is a diagnosis. An expert system spots them, child development specialists review them, and what reaches you is an observation together with what you can do about it — never a label placed on your child.
The reversal
The danger isn't the tablet. It's ignorance.
These children will live and work in a world saturated with artificial intelligence. We can keep them away from it until they are fifteen — 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.
😟 A consumer AI in a child's hands
- Answers anything, at any age, with no filter designed for them
- Lets itself be called "friend", builds emotional attachment
- Does the homework for them and switches off their curiosity
- Built to maximise time spent on screen
- Conversations invisible to parents
- Never says "I was wrong"
🌟 Cogency-Kids
- Every answer calibrated to the age band before it is shown
- Declares itself a program, refuses the role of sole confidant
- Asks questions instead of handing over the finished answer
- Time budget enforced server-side, and it tells them to go play outside
- Full transcript available to parents — and the child knows it
- Congratulates the child when they catch it out
Observed, not assumed
This is not a hypothesis. It is a little girl.
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.
-
4 months
First contact
She touches the screen. Not randomly: she is looking for a reaction, and she finds it.
-
7 months
A clear response
She reacts distinctly to learning apps. The screen is no longer a light — it answers back.
-
18 months
Four languages
She counts in Chinese, English, French and Arabic. At an age when we are still waiting for first words.
-
2 and a half
Fluency
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
The Guard Circle
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 — and none of them is optional.
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 — it never leaves the server.
Model 1
Piko drafts
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
The Guardian reviews
A second model, from a different provider, checks the draft: safety, honesty, age fit, healthy attachment, autonomy. It returns a verdict — accept, adjust, refuse. If it is unreachable we fall back to strict mode rather than let anything through.
To the parents
The Bridge
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.
🔒
Personal data simply does not exist
The child has no account, no email, no password. A first name — or a nickname — and an age, under their parent's account. There is nothing to steal.
👁️
Transparency is announced by Piko itself
"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.
🚫
Zero third parties on the page
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
Seven Worlds, one direction
The child chooses where to go. Each World changes how Piko answers — not just the scenery.
🔎
Curiosity
Ask your question, even the strangest one
The answer is calibrated to their age and always ends with an invitation to go and look in real life.
🎨
Create
Invent a story, a machine, a song
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
Learn how I work — and how I get things wrong
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
Feelings, friends, and hard days
Piko listens, names the emotion, and always walks the child back to a trusted grown-up. It replaces nobody, and it says so.
🖍️
Draw
Grab your crayons, let's draw together
A sheet opens inside the app and the drawing stays with you: nothing is sent, nothing is stored. Piko guides step by step, then asks the child to describe their work.
🗣️
Everyday phrases
Learn the phrases you use every day
Saying hello, thank you, naming a need, asking for help. One phrase at a time, repeated, then played out in a mini situation. Every try is cheered.
🕵️
Piko Agency
Solve missions, crack codes, rise through the ranks
A digital puzzle game inspired by challenge sites: secret codes, mysterious images and logic. No violence, no public leaderboard.
Piko's 5 rules
Piko announces them itself on the very first exchange, and repeats them whenever asked.
- 1
I am a program, not a person. I have no body and no feelings.
- 2
I can be wrong. Always check with a grown-up or a book.
- 3
Your parents can read everything we say. Nothing is hidden.
- 4
I keep no secrets. If something scares you, we tell a grown-up.
- 5
The real world is much bigger than me. Go play outside!
Three ages, three Pikos
A four-year-old and an eleven-year-old are not talking to the same AI
This is not a tone setting: answer length, vocabulary, the topics covered and the topics handed back to a grown-up all change entirely.
🐣
Little Explorer · ages 3-5
Maximum 45 words. Six-to-ten-word sentences, one idea at a time, everyday words only. Read-aloud on by default. 15-minute sessions.
🚀
Adventurer · ages 6-8
Maximum 110 words. One new word per answer, always explained, plus a concrete comparison. Piko encourages the next question. 25-minute sessions.
🛠️
Builder · ages 9-12
Maximum 220 words. School vocabulary, technical terms allowed when defined, examples and counter-examples. Never condescending, it invites doubt. 40-minute sessions.
For parents
You stay in control, without having to police
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.

💛 Amina asked why people argue. A good chance to talk about it tonight.
This week
She keeps returning to desert animals, volcanoes and how bread is made. This week she grasped that Piko can be wrong — she corrected it twice. To do together: bake bread and watch the dough rise.
⏱️ A time budget that actually holds
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.
📖 Everything is readable, nothing is summarised away
You get the full transcript, with, for each answer, the model that wrote it, the model that reviewed it, and the verdict returned.
