Jero is the tutor your child talks to: curious, patient and happy to be wrong now and then. Those big ears mean he listens first. Behind him, μikor diagnoses, chooses, assembles, explains and paces, and answers to your child's Digital Twin.
A question first, then a hint, then an answer only if it's needed.
Sometimes Jero gets a problem wrong and your child corrects him. Explaining an idea is one of the best ways to learn it.
Jero teaches in the language you speak at home, and talks with grown-ups too.

Every answer updates an estimate of what your child has mastered, so μikor never reteaches what is known or skips what is not.
Maya says 2/3 is bigger than 3/4. μikor picks the kind of hint that has helped her remember before. Switch the style to compare.


A global network of subject experts, teachers and cultural specialists reviews Jero's content for accuracy, cultural fit and bias.
Every explanation, problem and project is mapped to the learning objectives for each age, so Jero stays on track.
Minimal collection and encryption everywhere. You can view, export or delete your child's data at any time.
Fairness, transparency and bias mitigation are reviewed for every model μikor uses.
