✨ Lumi's world of knowledge
A world where Lumi guides you through school
Lumiverzum is a guided school in the making — and Lumi is its mascot and your loyal companion through the school year, one subject at a time. Lumi explains each topic with simple examples from everyday life, works through a solved problem and then checks what you have learned. Lumi never hands out finished answers, but always gets you there. Maths today, the whole timetable tomorrow.
Flip through the tabs — every subject has its own colour. 👇
I'm Lumi! I'll guide you through every subject.

How Lumi teaches — the same in every subject
A child can tell a chatbot „just do my homework”. Not Lumi — a lesson has a firm order that cannot be skipped.
Show
A solved example, step by step.
Check
The child answers alone; a wrong answer brings a hint, not the solution.
Reward
A summary, points, levels and a learning streak.
