Personas define facts for simulated users that interact with your agent in agent simulations. They determine WHO the simulated user is and HOW they behave during conversations.

​
Quickstart

​
Create a new persona

From the sidebar, click Personas to view your existing personas. Click Add persona to create a new persona.
Personas

​
Add the label and characteristics

Add label and characteristics
Give a meaningful label to the persona (e.g. shy, pregnant mother in her third trimester) and define its characteristics.

​
Guidelines for defining characteristics

Define two key aspects:
  1. WHO: Specific details about the persona
    • Name, age, occupation
    • Location, background
    • Language proficiency
    • Any other relevant details required for your agent simulation
  2. HOW: Behavioral traits
    • Communication style (polite, impatient, formal)
    • Speech patterns (slow, uses filler words)
    • Temperament (calm, easily frustrated)
Example Characteristics: 
You are Rajesh, a 45-year-old farmer from rural Karnataka who
speaks primarily in Kannada with limited English proficiency.

You are polite and friendly but speak slowly with natural
pauses like "uhh" and "umm". You have a calm and patient
demeanor but can become frustrated when technical jargon is used.

You prefer simple, straightforward explanations and often ask
for clarification. You tend to repeat important information
to make sure you understood correctly.
Avoid including task instructions in characteristics. Use Scenarios to define WHAT the persona should do.

​
Configure voice settings

Select the gender and language for the persona.

​
Define interruption sensitivity

Real users often interrupt agents mid-sentence. Configure how likely this persona is to interrupt:
LevelBehavior
NonePersona never interrupts
Low25% chance of interrupting
Medium50% chance of interrupting
High80% chance of interrupting

​
Save the Persona

Best Practices

Creating realistic personas

  1. Be specific: Include concrete details (name, age, occupation, etc.)
  2. Define communication style: How do they speak? Fast, slow, formal, casual?
  3. Include limitations: Language proficiency, technical knowledge, etc.
  4. Add emotional traits: Patient, impatient, friendly, formal
