# Storing data in variables

Variables keep state as your flow runs, so you can reuse values across nodes and paths without rewiring everything.

## Create a variable

Open the **context menu** and choose **Create new Variable**. Give it a name, a type, and an optional default value. FlowGenie will add matching **Read** and **Write** nodes you can drop anywhere in the canvas.

## Read and write values

Use **Read `yourVariable`** to pull the latest value into any node. Use **Write `yourVariable`** to update it mid-flow after a branch, loop, or transformation.

## Use variables inside text

In a **Multiline text** node, insert `{{variableKey}}` to interpolate the current value. This is useful for dynamic messages, API payloads, and prompts.
