# Workflow variables

Workflow variables let you store and reuse information within the scope of **a single [Workflow](https://botpress.com/docs/studio/concepts/workflows.md)**. They're great for:

* Storing an AI task's output
* Saving and reusing user input
* Organizing data returned from an API call

> [!NOTE]
>
> Workflow variables are only accessible in the Workflow they were created in. If you need a variable to be accessible in multiple Workflows, use a different [variable scope](https://botpress.com/docs/studio/concepts/variables/overview.md#variable-scopes).

> [!TIP]

> Need help getting started with variables? Check out our [introduction to variables](https://botpress.com/docs/studio/concepts/variables/overview.md).

## Read a Workflow variable

You can use `{{workflow.variablename}}` or `@workflow.variablename` to read a Workflow variable. For example, in a **Text** Card:
