There are two main parts of each AI bot: the persona and the background.

​
AI Persona

Overview: The AI’s name, appearance, voice, and personality
  • Name - The AI’s name
  • Appearance - Either the AI’s profile picture or live avatar option
  • Voice - The voice model the AI uses (see the drop down menu at the top of each provider’s tab to see price estimates)
  • Personality - The AI’s personality type, style of speaking, confidence, professionalism, assertiveness, etc.
Do not include any background or situational context in the Persona. That belongs in the Background.

​
AI Background

Definition: A general field that lets you input the AI’s relevant situation, background, pains, needs, etc. Components: There are only two fields for the AI background:
  • Title - The AI’s role and company
  • Situation/context - Any relevant context to the situation. Common data included here for sales scenarios is:
    • Pain points/Specific needs
    • Budget/income level
    • Decision criteria
    • Decision makers
    • Competition knowledge
