# Workflow variables

Workflow variables let you store and reuse information within the scope of **a single [Workflow](/studio/concepts/workflows)**. 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](/studio/concepts/variables/overview#variable-scopes).
</Note>

## Read a Workflow variable

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