The knowledge graph

See how everything you learn connects

Knaph maps knowledge as concepts and the links between them, so you always know what you're ready for, what to come back to, and why.

1. 1

   Prerequisites

   A concept opens once what it builds on is mastered, so you're never asked to learn something that can't make sense yet.

2. 2

   Depth

   Concepts have levels. Some deeper levels open only after you learn a later concept — you come back and see the old idea differently.

3. 3

   Review

   What you've learned comes back for review at growing intervals, so it stays learned.
