Use instructions and personas to shape how your chatbot responds to visitors. Instructions define what your chatbot knows and how it behaves, while personas control its tone and communication style.

Chatbot instructions

Instructions are system prompts that guide your chatbot’s behavior and knowledge boundaries. You can create multiple custom instructions and switch between them based on your needs.
  • Default Behavior
  • Custom Instructions
By default, SiteGPT uses a built-in system prompt that:
  • Analyzes provided context chunks with similarity scores
  • Generates accurate responses based on your trained content
  • Uses a fallback message when information is insufficient
  • Maintains a clear, professional, and friendly tone
You can customize the Fallback Message that appears when the chatbot cannot find relevant information to answer a question.

Chatbot personas

Personas define your chatbot’s personality and communication style. Choose from pre-built personas or create custom ones to match your brand voice.

Built-in personas
