No one should learn alone.
We created Lumi, an AI voice tutor that guides every student with questions, at their own pace and in their own language, until they find the answer themselves. We built it so that no student falls behind for lack of someone by their side. And we work alongside teachers, in service of the passion that led them to teach: helping every student go as far as they can.
Official and school-specific curricula
We follow the curricula of Spain, Switzerland and France: LOMLOE, PER, Lehrplan 21, Piano di studio and Éducation nationale. And we adapt to each school's own educational project.
European framework
We design Lumi in line with the GDPR, the AI Act and the child-protection measures the EU is currently considering.
European infrastructure
Hosted on Microsoft Azure, in European Union data centres.
Accessible by architecture
Learning happens by voice, without depending on a screen. Accessibility isn't an add-on: it's the foundation.
Our commitment to those who teach
For the education system
A teacher can't sit with every student every afternoon. We can accompany each one, using the method and topics the teacher chooses, and give them back what they need to know for their next class.
When they get stuck at home, they have someone to ask. We guide them with questions, in their language, at their pace and following their year's curriculum, until they understand it themselves.
Set topics and assignments for the whole class or for specific students. We work through them with each student and tell you what has been consolidated and where each one is stuck, so you walk into your next class knowing where to start.
We work with the tools your school already uses, without replacing them. We roll out Lumi class by class, adapted to your educational project and with the usage limits you set, and we support you every step of the way.
Tailored to your school
Beyond official curricula, we can design a tutor of your own with you: with your educational project and materials, your name, your visual identity and even your own characters.
What never changes: the Lumi method and our safety commitments.
Let's talk about your project →The Lumi method
What a student discovers on their own is what sticks. That's why our tutor asks, listens and redirects. The Lumi method is rooted in the Socratic tradition, and we enrich it every day with the best of educational research.
Student · What's the solution to 2x² − 3x − 5 = 0?
Tutor · Before looking for it, what does the sign of the constant term tell you about how many solutions there can be?
Student · That it's negative… so there'll be two.
Tutor · Well spotted. How could you check it?
Free Learning
There's an age when everything starts with a "why?". We created Free Learning so those questions always find someone eager to explore them. And because for many children it will be their first conversation with an artificial intelligence, we designed it as a safe place where they learn new things, and also how to ask good questions. It's a space for learning, not an open chat: we explore science, nature, history, art and the world around us, and calmly redirect anything that isn't about learning.
Lucas and Lucía answer with stories suited to their age, and every answer opens a new question. Behind every conversation there's always a goal: leading them, question by question, towards something new to discover.
A safe way to teach students to ask, to cross-check and to use artificial intelligence to think, not to copy.
Three age bands, each with its own topics and tone. Age is set by the account, not by what the child says. And any topic that isn't right for their age, we calmly redirect to a trusted adult.
Meet Lucas and Lucía
Lucas and Lucía are our tutors: two artificial intelligences with different styles and the same method. They speak to every student in their own language (Spanish, French, German, Italian and English) and follow each country's official curriculum. And they always present themselves as what they are: an AI in service of learning.
Lucas
Patient, funny and full of energy. If something gets stuck, he finds another way to look at it, and another, and another, until you understand.
As a tutor · He covers every subject, from primary to upper secondary. His strength is getting students unstuck: when a student is blocked, Lucas changes the angle until the idea clicks.
Lucía
Endlessly curious, imaginative and calm. She connects what you ask with something you didn't yet know you were interested in.
As a tutor · She covers every subject, from primary to upper secondary. Her strength is making sense of things: she connects every topic to the real world so students understand what what they learn is for.
The same method, the same care. Two styles, every subject and every age: each student chooses the one they prefer.
And if your school wishes, we'll design your own characters with you. Let's talk →
Lumi Barrier-Free
From day one, we decided Lumi would be accessible by architecture, not as an add-on. Because we believe in what artificial intelligence can do for education: that every student, whatever their barriers, can count on help to learn. And we want to play an active part in that change, putting everything we know, and everything we dream of, into breaking down those barriers or, at the very least, reducing them to a minimum.
Designed for students with special educational needs:
Lumi Barrier-Free adapts the experience to every need. For visual impairment: voice log-in, spoken descriptions of graphs, figures and equations, and screen-reader compatibility.
We designed it to help, and we want you to help us make it better. We bring the commitment. To make it real, we need schools, specialists and public and private organisations willing to build it with us and test it with their students.
I want to get involved →Child safety
Building well takes time. Building for children takes longer. These are our commitments to every student, every family and every school.
A student's voice is only used to talk during the session. We don't record it or store it.
We delete conversations after 30 days and keep only the learning summary. We never use a student's data to train models without separate consent, which is off by default.
No student starts without permission from a responsible adult, and their school can follow their progress.
At any time, with a button or with their voice, a student can stop the session. We point them to a trusted adult and to the helplines in their country.
Daily limits, a maximum session length and a night-time break, which the school can adjust.
Our tutor always introduces itself as an artificial intelligence. Teachers see learning summaries, never the conversations.
No ads. We never sell data.
Our commitment to the European child-protection framework →About us
A year ago, one of us, Charlie, wanted his daughter to start using artificial intelligence to understand what she was studying, not to copy answers. At first, the AI kept giving her the solution. But Charlie persisted: he searched, tested and adjusted, until one day the AI stopped answering and started asking. His daughter understood the problem on her own, and in French, the language she studies in, where he could no longer keep up with her.
That afternoon convinced him there was something to build. Nico and his team were looking for artificial intelligence projects to develop: Charlie pitched them two ideas, and one of them is Lumi today. Everything has grown since then, but we've kept the spirit we started with: to help and to create.
We're brothers, not by blood but by life. We met working at different companies, and the same passions and the same way of doing things brought us together. From that brotherhood came Lumi, and our name too: The Lumi Bros.

We're not a translated platform. We were born here.
Europe demands the world's highest standards for protecting children online. We don't see them as an obstacle: they're our starting point.
A student's data belongs to them and their family. That's why we keep the minimum, for the shortest time, and never sell it.
Five languages, the official curricula of every country and every canton, and each school's own project. Because in Europe there's no single way to teach.
