Weeks of moments
The home screen of the app, rebuilt for this site. Name and content are fictional.
01 · An example
How it works, with an example
Fictional example: Léa, aged 3. The name, the scene and the observations are made up.
The video
One Tuesday in October, at snack time, Léa shows her drawing to her father and tells him what she did. He films a short video with KOR’K Scan.
What the AI describes
For each milestone visible in the video, the AI notes what it sees and what it hears.
Language
Talks with you in conversation using at least two back-and-forth exchanges
ObservedLéa answers two questions from her father about her drawing, then asks him one.
Talks about at least one thing that happened during their day, like “I played soccer.”
EmergingExcerpt from the app, rebuilt for this site: the result of one video. Fictional example. The milestone
“Talks with you in conversation using at least two back-and-forth exchanges” is a 3-year milestone, in the Language area.
Language: 42 milestones, from 6 months to 7 years
6 months3 years7 yearsOne mark = one milestone. In colour, the one in the example. The monthly report
At the end of the month, this moment joins the others in the October report. For language, the report says “Observed: ~ 3 years and up”. It is an indication: it depends on the moments you filmed, and does not tell the whole story of your child.

05 · Questions
Frequently asked questions
What is it for?
KOR’K helps you move from an impression to dated, concrete observations that you can share with your doctor.
You film short everyday moments. The app links them to developmental milestones and presents them to you every month. An aid to observation, never a diagnosis.
What do I get out of it?
Every month, a report in five areas: language, social interactions, emotions, motor skills, routines. It shows, with dates, what was observed in your videos.
KOR’K Scan Pro adds the detailed report by area, the monthly recap, tracking over time, PDF export and several children.
What should I film?
A few seconds of play, a meal, a bedtime story. Ordinary moments, where your child lives.
Where do my videos go?
They are encrypted in transit and hosted in the European Union (Supabase, Frankfurt).
They are analysed by the Google Gemini API, on the paid tier: they do not train the AI. For the analysis, the videos are sent to Google (Gemini API). This processing may take place outside the European Union. The copy sent to Gemini is deleted after the analysis, and the child’s first name is never sent to Google.
Videos are deleted after 30 days at most, or at any time, in the app. They are never sold.
Do I need an iPhone?
Yes, for now. KOR’K Scan has been on the App Store since July 2026.
What about Android?
An Android version is on the way. It is not available yet, and we are not announcing a date.
How much does it cost?
The account is free: you film, and you receive a summary of the report.
KOR’K Scan Pro costs €9.99 per month, cancel anytime. Referrals earn detailed reports, for you and for the person you refer.
What if the report worries me?
Talk to your doctor, and show them what you have observed. KOR’K does not replace their advice.
