# Persona Chat

> Have one-on-one AI conversations with a synthetic persona — roleplay as them or analyze how they would react

Persona Chat lets you talk directly with a persona. The AI stays grounded in the persona's profile, the signals that shaped it, and any Knowledge pages you linked — so the conversation reflects what that kind of customer would actually say.

## Two Chat Modes

<CardGroup cols={2}>
  <Card title="Talk at mode" icon="user">
    Roleplay as the persona in first person. The AI responds as "I would..." — useful for rehearsing a sales pitch, testing a cold email, or simulating a support conversation.
  </Card>

  <Card title="Talk with mode" icon="user-group">
    Analyze the persona in third person. The AI responds as an analyst — "they would likely...", "their main concern is..." — useful for research prep, positioning work, or persona onboarding for your team.
  </Card>
</CardGroup>

Both modes use the persona's full profile and underlying signal data. They just answer from different vantage points.

## Starting a Chat

1. Open **Personas Chat** or any persona from your library
2. Choose a saved panel, a specific persona, or people directly when prompted
3. Pick **Talk at** or **Talk with** when you start
4. Send messages — responses stream back in real time

You can have multiple chats with the same persona — each is saved separately with its own history.

## What a Persona Knows

When you chat, the AI has access to:

* The persona's full profile — personal, professional, psychographics, and company context
* The signals that were used to generate the persona (and any new signals matching their segment)
* Any Knowledge page you linked to the persona for extra context

Personas can cite specific signal IDs when they back up a claim, so you can click through to the underlying customer data.

## Good Uses for Chat

<Tabs>
  <Tab title="Messaging">
    * "How would you react to this email subject line?"
    * "What's the first objection you'd raise to this pitch?"
    * "Rewrite this value prop in your own words."
  </Tab>

  <Tab title="Discovery & Sales">
    * "Walk me through your current workflow for X."
    * "What would make you take a demo of a product in this space?"
    * "How do you evaluate vendors when buying?"
  </Tab>

  <Tab title="Product & Research">
    * "What problems do you run into today that we might not know about?"
    * "Which of these three concepts sounds most useful, and why?"
    * "What would stop you from adopting this feature?"
  </Tab>

  <Tab title="Onboarding a Teammate">
    Switch to **Talk with** mode and ask:

    * "Summarize this persona in 3 bullets."
    * "What are the top 3 risks when selling to them?"
    * "Where do they already have tools that compete with us?"
  </Tab>

<Tip>
  Chat is great for fast iteration on one idea. When you need signal across a group — a panel of dozens of respondents — run a [Persona Test](./persona-tests) instead.
