# Analytics and the Knowledge Map

> Five views over your learning: mind map, knowledge map, retention, forgetting curve and KWL.

Source: https://cognipage.io/docs/analytics

Five views over the same data, each answering a different question about what you know. They are live: everything here is drawn from your own reading and recall history, not from averages.

**Where** Analytics · switch views with the tabs at the top right

## Mind Map

Your library as a tree: CogniPage at the root, then each **material**, the **concept groups** within it, and the **flashcards** under those. Click any node to open a panel with its detail — for a card, its recall rate and how many times you have reviewed it.

This is the view for "what have I actually built here?", and for spotting a material that produced far fewer cards than it deserved.

## Knowledge Map

The graph of your second brain: folders, notes, the concepts inside them, and the materials they came from — including concept-to-concept links that show how ideas relate across sources. Pan, zoom and click any node to read the note behind it.

Where the Mind Map is a hierarchy, this is a web. Dense clusters are subjects you understand from several angles; isolated nodes are things you read once and never connected to anything.

## Retention

A heatmap of where your memory runs hot and cold across topics. Warm areas are holding; cold ones are decaying. It is the fastest way to decide what to re-read rather than merely re-review — and it is what Home's *Avg Recall* card opens into.

## Forgetting Curve

Ebbinghaus's forgetting curve, fitted to *your* recall history rather than drawn from a textbook. It shows how fast your memory of a thing decays without review — and how each review flattens the curve, so the next gap can be longer.

You can scope it to a single material to compare how differently two subjects fade.

## KWL Chart

Per material, concepts are sorted into three columns:

**Know**

Concepts your recall history shows you have.

**Want to know**

Concepts present in the material that you have not demonstrated yet.

**Learned**

Concepts that moved from the middle column to the first — progress, made visible.

Building the chart for a material uses AI, so it needs an account and [credits](https://cognipage.io/docs/account).

## Reading the maps

All the graph views share the same controls: scroll or pinch to zoom, drag the background to pan, drag a node to move it, and click a node to open its detail panel. Click the background to close the panel. The legend under the map explains the node colours.

> Every one of these views needs history to be interesting. After two or three reading sessions they are sparse; after a month they are the clearest picture you will get of what you know.
