# Learning Stores

> Each store captures a different type of knowledge.

A Learning Machine coordinates multiple stores, each optimized for a specific type of knowledge.

| Store                                                       | What it captures                            | Scope        | Use case              |
| ----------------------------------------------------------- | ------------------------------------------- | ------------ | --------------------- |
| [**User Profile**](/learning/stores/user-profile)           | Structured fields (name, role, preferences) | Per user     | Personalization       |
| [**User Memory**](/learning/stores/user-memory)             | Unstructured observations and facts         | Per user     | Context retention     |
| [**Session Context**](/learning/stores/session-context)     | Goals, plans, and progress                  | Per session  | Long-running tasks    |
