# Variables

Variables help your AI Agent collect, store, and reuse information throughout a conversation. They allow the Agent to remember what a user has said, access context about the environment or channel, and pass structured data between different parts of your automation.

This topic explains the different types of variables the AI Agent uses—such as [Autocapture Variables](/docs/automation/variables/using-variables#autocapture-variables) that extract information automatically, [Metavariables](/docs/automation/variables/using-variables#metavariables) that provide built-in context from the user's environment, along with [Global](/docs/automation/variables/using-variables#global-variables) and [Sensitive variables](/docs/automation/variables/using-variables#sensitive) that help manage state and protect user data. You'll also learn [how variables are created](/docs/automation/variables/using-variables#create), [populated](/docs/automation/variables/using-variables#populate), and [how to use them](/docs/automation/variables/using-variables#use).

Whether you're capturing user inputs, storing API responses, or tailoring the Agent's responses based on known details, variables provide the foundation for building dynamic, context-aware conversational experiences.
