Make it truly yours

Once you’ve finished configuring the Themes tab, your chat will reflect your visual identity much more accurately. The content remains the same — but the visual experience becomes more professional, memorable, and aligned with your brand.

Testing your chat

After saving your changes, all customizations will be applied automatically and your chat will be ready to share. Before doing so, we recommend testing your chat using the Playground. The Playground is a dedicated environment where you can experiment with your chat’s knowledge, personality, and responses without consuming messages from your plan.

Why customize your chat?

These settings allow Attlas to communicate exactly the way you want. You can create a chat that is:
  • More professional for businesses and organizations;
  • More casual for creators and communities;
  • More welcoming for education, support, or guidance;
  • More creative for entertainment and interactive experiences.
All of this can be configured in a simple, intuitive, and flexible way, ensuring that your chat’s personality reflects your brand and delivers a more consistent experience to users.
