KOR'K Sensor

KOR'K Sensor 01 The story

Chapter 01

The story

KOR'K helps parents of children aged 2 to 7 observe their child's development, using videos of everyday life. It is an aid to observation, never a diagnosis. The Sensor is the next step, and it was the starting idea: capturing those moments without taking out a phone.

The origin

My little brother

KOR'K comes from my little brother. When he was 4, it took two years to get a diagnosis. During those two years, we, his family, saw things every day that nobody else saw: how he reacted, how he played, how he lived in his surroundings. Without knowing what to do with it.

KOR'K is the tool I wish we had had back then. Not to watch over him: to finally be able to tell the paediatrician, “look, this is what we see, every day”.

The vision

A world where no child grows up without being understood.

The name

KOR
For Korczak, the educator who put the protection of children at the centre.
CORE
The centre, the essential.
CORTEX
The brain: understanding how a child grows.

Who I am

The urge to build things came early. At 16, I taught myself web design and development, and launched DDale, my agency, with real clients. I now study business at EDHEC and data and AI at Albert School and Mines Paris – PSL. KOR'K is not my first project, but it is the first one that comes from something personal.

The need

What KOR'K is for

KOR'K comes before the doctor. It helps a parent who is worried, even vaguely, about their child's development to turn that worry into dated, concrete observations: what the child does, says and shows in everyday life, with the video to back it up.

That moment matters. The French National Authority for Health (HAS) puts it this way: “Whatever the age, any concern parents have about their child's neurodevelopment must be considered a warning sign.” The worry still has to be put into words. The answers are scattered: forums, the health record book, appointments spread far apart. The apps that exist mostly rely on questionnaires that the parent fills in themselves.

I wanted to start from something else: spontaneous videos of real life, which are more concrete and more telling. The parent keeps a dated record, and can bring precise examples to their paediatrician.

What comes next belongs to the doctor: looking, interpreting, deciding. KOR'K helps people observe; it does not say what the child has.

The age range

Why from 2 to 7

A parent's worry can arise well before the age of 2. The developmental milestones of the US CDC, to which KOR'K Scan links its observations, start at 2 months; the HAS recommendation covers children from 0 to 7.

Starting at 2 is my own choice. Analysing videos of children under 2 was difficult. Being able to reach them is still a work in progress.

The top of the range, 7, coincides with the upper limit of the HAS recommendation.

Today

KOR'K Scan, online since July 2026

A child of about four, seen from behind, stacks wooden blocks on a rug; in the foreground, a parent's hands film them with a phone.
AI-generated image (Artlist, Nano Banana Pro). An illustrative scene: neither the child nor the parent is real. This is the gesture, filming at the right moment, that the Sensor aims to make unnecessary.

  1. 1

    Film

    The parent films an ordinary moment of about a minute: playing, eating, talking.

  2. 2

    Describe and place

    The AI describes only what is visible and audible, and relates it to the main developmental milestones for the child's age (CDC 2022 and WHO references).

  3. 3

    One report a month

    By area (language, motor skills, social interaction): what is observed, what is emerging, what deserves a second look.

An example

From the video to the paediatrician

  1. 1

    The filmed sequence

    Everyday moments, filmed on the phone by the parent of a 2-year-old. The videos are not shown here: they are deleted after 30 days, and only the report is kept.

  2. 2

    What the AI describes

    For the “Social interactions” area, the month's summary: “The child shows a wish to interact by seeking the attention of those around him to show his abilities and achievements.”

  3. 3

    The milestone it links it to

    “Shows you what he can do (‘look at me!’)”: observed.

  4. 4

    What the report says

    Two ideas for home: “Imitation games (phone, doll, toy kitchen)” and “Time with other children, without forcing sharing”. And, for each area, what would be worth mentioning when the occasion arises, without alarm.

  5. 5

    What the parent brings to the paediatrician

    The month's report, as a dated PDF: the milestones observed in each area (language, social interactions, emotions, motor skills, routines).

  6. 6

    What stays with the doctor

    Everything else: seeing the child, interpreting, deciding. The report says so itself: “Indicative estimate based on the behaviours observed. Does not replace the opinion of a health professional.”

Tomorrow

Why a device

The device did not come after the app: it was my starting idea. As early as March 2026, my first file describes a diamond-shaped sensor placed in a corner, with a fabric front, “closer to a speaker than to a camera”. Yet I released the app first: a physical object is costly and risky (manufacturing, certification, production), and each step has to reduce the risk and fund the next one.

The Sensor I imagined in March is not exactly the one going to Nuremberg. I saw it under 100 g, with a 160° camera and all the analysis done inside the device. The prototype weighs about 0.5 kg, its camera sees 120°, and the analysis goes through the cloud.

Filming means remembering to take out your phone at the right moment. The most telling moments often happen when nobody is filming. The Sensor is a small device placed in the corner of the bedroom, which captures those moments in the parent's place.

In time, I want the analysis to happen inside the device itself, so that no video leaves the home. That is not the case today. The prototype films and transmits; the analysis is done in the cloud, by KOR'K Scan, exactly as for a video filmed on a phone.

The line

Observe, don't watch over. It is neither an assessment tool nor a surveillance camera: it is an aid to observation.

The starting point

The constraints I set myself

0.5 kg

for about 12 × 12 × 10 cm: a discreet object that can travel in cabin luggage

A corner

of a room, with WiFi and a mains socket

4 weeks

for a working prototype, at 20 hours a week

€600

at most for the prototype

My rules

  • Move forward phase by phase, validating each step before the next.
  • Buy nothing without validating it first, and check every price online, with its date.
  • Never let anyone believe that the analysis happens inside the device if it does not.
  • Treat safety as for a product intended for a child's bedroom.

Why now

A first contact with real users

Selected by PSL-Pépite for the EELISA Prototype Contest in Nuremberg, I am presenting KOR'K Scan and this first Sensor prototype to a European audience. KOR'K Scan works in France: what remains is to check that it meets a real need beyond it, and that parents understand it at first glance. For the Sensor, this will be its very first contact with real users: its shape, its place in the home, and the trust it inspires. The event in detail
