About Lulio

Who is behind Lulio

Lulio is published by Pierre Filstroff, who designs and oversees the episodes as well as the guides published on the site. He runs the project under a Contrat d'Appui au Projet d'Entreprise (a French business-support contract) signed with the Créacité association.

The publisher, the host, and full contact details are in the legal notice. The data is hosted in France.

Why Lulio exists

Frequent story reading helps a child's language, but the effect depends on regularity. In a meta-analysis of 19 randomized controlled trials covering 2,594 children aged 1 to 6, the benefit becomes minimal when shared reading is infrequent.

Keeping up that rhythm means having a story ready every evening that your child wants to hear. Lulio tries to solve that: a new episode each evening, in a saga where your child is the hero, with their siblings, pet, and comfort toy among the characters.

How the guides are written

The site publishes 54 guides, built around a pillar guide on children's sleep. They fall into four families: sleep (bedtime routine, needs by age, naps, the bedroom), sleep problems (night wakings, parasomnias, apnea, bedwetting, teeth grinding, insomnia), reading and language, and evening wellbeing (screens, fears, food, separation anxiety). Topics follow the questions parents ask around bedtime, from the evening routine to the problems that justify seeing a doctor.

Each guide lists its sources at the bottom of the page, with a link to each: studies published and indexed on PubMed or identified by DOI, meta-analyses, and recommendations from institutions such as the American Academy of Pediatrics, France's Haute Autorité de santé, the WHO, the CDC, the NHS, and the National Sleep Foundation. A modest effect is described as modest.

Each guide shows its publication date and, when it differs, its update date. All the guides are listed on the Resources page.

How the stories are produced

Each episode is written for your child using an artificial-intelligence text-generation model (Anthropic), from what the parent entered: first name, age, siblings, companions, and chosen universes. The voice is a speech synthesis (ElevenLabs) produced from the generated text. Both providers are based outside the European Union and are named in the privacy policy along with the data sent to them.

Stories are organized into sagas of 3 to 7 episodes: the same characters, a plot that moves forward, an ending. The theme catalog is closed, which limits what can be told, and automated checks review the episodes. If one turns out to be inappropriate despite them, Lulio can withdraw or edit it. A thumbs-down lets the parent say why an episode missed (too long, too simple, too scary, off-topic, incoherent), and the following episodes take it into account.

These are entertainment, not educational, medical, or psychological advice. The parent remains responsible for choosing episodes and for guiding the reading. The visuals on the home page (video and photographs) are also AI-generated and show no real child.

What Lulio does not do

The guides inform, they do not treat. They are no substitute for medical advice and cannot support a diagnosis. Several of them (sleep apnea, bedwetting, parasomnias, insomnia) say when to see a health professional.

As of today, no guide has been reviewed by a health professional. They report what the published sources say and rest on no clinical validation. If you are a doctor, pediatrician, or researcher and you spot a mistake or a stronger source, write to us: we will correct it.
