What Is a Knowledge Graph — and Why We Built Amal on One
When your child learns Arabic, they are not really learning "Lesson 1, then Lesson 2, then Lesson 3." They are building a web of connected ideas: the shape of a letter, the sound it makes, how it joins to the next letter, how those letters form a word. Miss one connection, and everything downstream wobbles.
That web has a name in engineering: a knowledge graph. It is the quiet foundation underneath Amal, and this short series explains — in plain words — what it is, how it works, and why it makes your child's learning better.
A graph in one sentence
A knowledge graph is a map of everything there is to learn, where:
- Every concept is a dot on the map — we call it a node. The letter ب. The sound /b/. Adding numbers up to ten. A short surah.
- Every prerequisite is a line connecting two dots — we call it an edge. The line says "learn this before that."
So the graph doesn't just hold a pile of lessons. It holds the relationships between them. It knows that "joining letters into words" sits on top of "the sound each letter makes," which sits on top of "recognising the letter's shape." You can't teach the connected form of a letter before the child knows the letter at all — and the graph encodes exactly that.
Why not just a list of lessons?
Most learning apps are a flat playlist: a fixed sequence everyone marches through in the same order. It looks tidy, but it hides a problem. A playlist can't tell you why lesson 12 comes after lesson 11, and it can't rearrange itself when a particular child is ready to leap ahead — or needs to go back.
| Flat lesson list | Knowledge graph | |
|---|---|---|
| Structure | One fixed line | A connected map |
| Knows prerequisites? | No | Yes — every edge |
| Adapts to the child? | Same for everyone | A path per child |
| Add a new surface (book, printable)? | Rebuild by hand | Re-render from the graph |
One graph, one source of truth
Here is the decision that shapes everything: Alphazed keeps one knowledge graph, and every single learning surface reads from it. Not one curriculum for the app and a different one for the workbook. Not one team writing lessons and another writing the printables. One graph — the single source of truth.
Inside it live three simple things:
- Concepts — the teachable ideas (the nodes).
- Dependencies — the "learn-this-before-that" links (the edges).
- Assets — the pictures and media attached to each concept.
On top of that shared map, Amal keeps a private, per-child layer that tracks what your child knows. The map is the same for everyone; the journey across it is unique to each child.
What it teaches today
The graph is live for the Amal beta across four subjects, in Arabic and English side by side:
- Arabic — letters → words → sentences
- Math — ages 3–8, every basic operation
- English — years 2–8
- Grammar
Amal is already trusted by tens of thousands of families across 50+ countries, and the graph is how we keep one coherent curriculum behind all of it.

This is the pillar post. The other four each take one thread and pull it:
- How Alphazed Teaches Arabic With One Knowledge Graph — you are here.
- One Graph, Every Lesson: Apps, Books, and Printables — how one concept becomes a lesson, a printable, a book, and more.
- Adaptive Learning: A Knowledge Graph Per Child — how the graph picks the right next step for each child.
- Why a Knowledge Graph Is Good for Your Child — the four benefits, from a child's point of view.
- For Parents: See Exactly What Your Child Knows — the knowledge-map you can actually see.
