Tailor-made stories
for every child, every night
Their face, their plush, their everyday adventures: your child becomes the hero of illustrated stories you read and explore together through quizzes, discussions and drawing.
No AI talking to your child, no solo screen time
the ritual stays in your hands
In-house SOII technology, patent-protected
for narrative coherence from one scene to the next
Our vision
Stories that look like your child, in a framework designed for parents.
Read, discuss, play
The book as a parent-child playground
Quizzes, discussion prompts, free drawing: every story becomes a shared moment.
Characters that come to life
Visual consistency guaranteed across scenes
Photos, drawings or avatars: your characters keep the same look from one scene to the next.
Four approaches, one framework
Each mode has its educational intent
Four modes designed with the LPNC / Babylab, each with its own pace and objectives.
Parents in charge
AI that serves you, never your child
You create, you review, you launch every story. Your child never interacts with the AI: they listen to a story with you, like a book.

A purpose close to our heart
Augmentative and Alternative Communication (AAC)
At SOII there is a wish to do something for those — a little different, often overlooked, sometimes little known: children for whom even the words used to describe them keep shifting. Whatever the name, it is them and their families we are also thinking of.
That is why we are building, step by step, SOII components dedicated to AAC, alongside partners from public research.
In collaboration with researchers from Université Grenoble Alpes and CNRS, at LIG and GIPSA-Lab
