Knaph
The Human Knowledge Graph

Learn how ideas connect.

Knaph maps what people know as concepts and the links between them. Learn each idea in the order it builds on the others, prove it to yourself, read how people first worked it out, and go hands-on in a course.

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.

  • Mastered
  • Open
  • Locked
  • Comes back deeper

How we came to know it

Not lessons: the history of an idea, read one page at a time.

Courses

Every lesson teaches a concept on the map. Start with the first one; there's nothing to install to begin reading.

Why we're building this

Knowledge isn't a list of courses. Every idea rests on others and opens up new ones, and each was worked out by real people, often over centuries. Knaph is an attempt to map that whole web, one concept, one course and one story at a time, in English and in Farsi.
