# Digital Twin

A Digital Twin is a causal model of your business or system. Unlike traditional predictive models that only learn correlations, a Digital Twin understands cause and effect—enabling simulation, optimization, and counterfactual reasoning.

***

### Building a Digital Twin

[**Creating a Digital Twin**](/user-guide/creating-digital-twin.md)

Start here. Learn how to create a Digital Twin from a Data View, choose between static and temporal models, and run causal discovery.

***

### Understanding the Model

[**Causal Graph**](/user-guide/causal-graph.md)

The causal graph shows discovered cause-and-effect relationships. Learn to read, interpret, and refine the graph with domain knowledge.

***

### Using the Model

[**Simulations**](/user-guide/simulations.md)

Run what-if scenarios, optimize decisions, find root causes, and predict outcomes. This is where causal understanding becomes actionable.

***

### Comparing Models

[**Model Comparison**](/more-details/digital-twin/model-comparison.md)

Compare different versions of your Digital Twin or compare models across twins. Understand exactly what changed in structure and parameters.

### The Digital Twin Interface

Once you've created a Digital Twin, you interact with it through several tabs:

[**Digital Twin Tabs**](/more-details/digital-twin/tabs.md)

* [**Home Tab**](/more-details/digital-twin/tabs/home-tab.md) – Overview, version selection, quick actions
* [**Config Tab**](/more-details/digital-twin/tabs/config-tab.md) – Data view selection, field configuration, constraints
* [**Relationships Tab**](/more-details/digital-twin/tabs/relationships-tab.md) – View and edit causal relationships
* [**Path Analysis Tab**](/more-details/digital-twin/tabs/path-analysis-tab.md) – Sankey diagrams showing causal flow
* [**Evaluation Tab**](/more-details/digital-twin/tabs/evaluation-tab.md) – Model quality metrics
* [**Simulation Tab**](/more-details/digital-twin/tabs/simulation-tab.md) – Run all simulation types
* [**Comparison Tab**](/more-details/digital-twin/tabs/comparison-tab.md) – Compare model versions

***

### Workflow

A typical Digital Twin workflow:

1. **Create** – Select a Data View and run causal discovery
2. **Review** – Examine the discovered causal graph
3. **Refine** – Add domain knowledge, resolve ambiguous edges
4. **Evaluate** – Check model quality metrics
5. **Simulate** – Test interventions, optimize, explain outcomes
6. **Iterate** – Improve the model based on what you learn
