About AI agent personas

AI agent personas let you apply a personality to an AI agent’s generative responses.
A persona is composed of three settings that work together to determine how your AI
agent presents itself when interacting with customers:


Business profile: A short description of what your company does. This
information gives the AI agent context so that it can give the most appropriate
responses.

Tone of voice: The general style of language the AI agent should use when
responding to customers.

Reply length: The approximate length of each of the AI agent’s
responses.

An AI agent’s persona applies only to the AI-generated responses it sends. It doesn’t
apply to the standard responses you customize in the AI agent’s
settings.



Configuring an AI agent persona

You can configure your AI agent’s persona to add personality to its AI-generated
responses.
To configure an AI agent persona


In Admin Center, click
AI in the sidebar, then select AI agents > AI agents.
Click the AI agent you want to configure a persona for.
Click the Settings tab.
Click the Persona section to expand it.
Under Business profile, enter one or two short, factual sentences in
English that describe what your company does. Keep this description
focused on simple text about your company's business domain, rather than
marketing-focused material that could potentially influence your AI
agent’s behavior.

Under Tone of voice, select one of the following options:

Professional: (Default) Polite and direct

Informal: Casual and friendly

Enthusiastic: Upbeat and friendly


Under Messaging reply length, select one of the following options:

Short: 50–60 words

Long: Up to 80 words


Under Email reply length, select one of the following options:

Short: Up to 150 words

Long: Up to 600 words







Your changes are automatically saved, but updates to the AI agent’s persona won’t be
presented to customers until you publish the AI agent.
