What it is

A new kind of
learning instrument.

Three interlocking parts, built from the ground up to work together.

The Map
An interactive force-directed graph of over 10,000 knowledge nodes spanning mathematics, science, humanities, arts, and more — organised into two layers: Foundational Knowledge and Emergent interdisciplinary fields.
Free to explore
Learn Mode
Click any concept and enter a focused learning session. An adaptive AI tutor walks you through it in four phases — Explain, Demonstrate, Practice, Meaning — adjusting to your responses in real time.
Learner plan
Learner Passport
Every concept you learn, every credential you earn, every reflection you write — collected in a structured, portable record. Cryptographically verifiable. Yours to export. Yours forever, regardless of platform.

How it works

Three steps.
A lifetime of learning.

1
Find a concept
Navigate the knowledge graph by zooming, panning, and filtering. Use curriculum filters — Estonian Main School, your own knowledge profile — or simply explore until something catches your eye.
2
Learn it deeply
Click "Learn this" and the adaptive tutor takes over. It explains the concept in short bytes, demonstrates with worked examples, then gives you practice problems — adjusting in real time to how you respond.
3
It lands in your Passport
Completed units are recorded in your Learner Passport — with your score, the date, and a cryptographic credential you can share. The map node changes colour. Your knowledge becomes visible.
The knowledge graph

Every domain. All at once.

Nine domains of human knowledge, hundreds of subfields, thousands of leaf concepts — connected into a single navigable space.
