​
End Users

End users are the people who interact with your embedded Char AI widgets.

​
User Tracking

Char AI automatically tracks end users to:
  • Maintain conversation history
  • Provide personalized responses
  • Enable analytics and insights

​
User Identification

You can identify users to maintain context across sessions: 
const widget = new CharWidget({
  apiKey: 'char_sk_live_...',
  user: {
    id: 'user_123',
    email: '[email protected]',
    name: 'John Doe'
  }
});

​
Anonymous Users

When no user ID is provided, Char AI creates anonymous sessions using browser fingerprinting.
Anonymous sessions persist within the same browser but don’t sync across devices.

​
User Data

Track custom attributes to enhance AI responses: 
widget.setUserData({
  plan: 'premium',
  company: 'Acme Inc',
  role: 'Developer'
});
