# Set the Visitor Chat Message Limit

> Configure how many messages a visitor can send in one chat session, from 7 to 25, and learn how the limit affects lead capture and credit spend.

AIBCO's Chat tab controls the visitor's conversation behavior. The message limit per session lets you decide how many messages a visitor can send before the assistant prompts them to become a lead.

<Steps>
  <Step title="Open the Chat tab">
    Go to **Dashboard → Chat**, then click the **Chat** tab.
  </Step>

  <Step title="Set the message limit">
    Find **Message limit per session** and choose a value between **7 and 25**.

  </Step>

  <Step title="Save">
    Click **Save** to apply the limit.
  </Step>
</Steps>

## How the limit works

When a visitor reaches the message limit, the assistant invites them to leave their contact details so you can follow up directly. This turn into a lead captures their name, email, phone, and message.

## Choosing a limit

| Mindset                   | Limit | Effect                                                                       |
| ------------------------- | ----- | ---------------------------------------------------------------------------- |
| Push toward leads quickly | 7–10  | Visitors become leads sooner; lower total credit spend per session           |
| Let visitors explore more | 15–25 | More room for questions and product discovery; higher potential credit spend |

<Tip>
  Each visitor message costs **1 credit**. The message limit also caps what a single conversation can spend.
</Tip>

<Note>
  The Chat tab is different from the other knowledge tabs (Text, Website, Document, Guardrails, and Greeting). It only controls visitor chat behavior, not what the AI knows.
</Note>

## What happens when the limit is reached

The assistant delivers a closing message that asks the visitor to share their contact information. Once submitted, the conversation ends as a captured lead.
