# User variables

User variables let you store and reuse information within the scope of **a single user**.

Any information you assign to a user variable will follow the user across multiple conversations with your bot. This makes user variables great for storing user-specific information, like:

* Personal details
* User preferences
* Notes from previous conversations

<Note>
  If you don't want your variable to follow the user between conversations, use a different [variable scope](/studio/concepts/variables/overview#variable-scopes).
