Analytics and the Knowledge Map
Five views over your learning: mind map, knowledge map, retention, forgetting curve and KWL.
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.
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:
Concepts your recall history shows you have.
Concepts present in the material that you have not demonstrated yet.
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.
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.
