Meet Jero

Jero, the Long-Eared Jerboa.

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.

Say hello to Jero.
He asks before he tells.

A question first, then a hint, then an answer only if it's needed.

Kids teach Jero.

Sometimes Jero gets a problem wrong and your child corrects him. Explaining an idea is one of the best ways to learn it.

He speaks your language.

Jero teaches in the language you speak at home, and talks with grown-ups too.

Five specialists, one voice

Diagnostic model
Finds exactly what your child is ready for next.

Every answer updates an estimate of what your child has mastered, so μikor never reteaches what is known or skips what is not.

Feedback that fits

The same mistake, explained three ways.

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.

I think 2/3 is bigger.
Jero
Hmm, look at the empty parts. Which bar has more chocolate missing?
Oh. Then 3/4 is bigger.
Jero
Yes! How did you know? Was it the empty part?
