# AI replies

> Let the workspace AI agent answer customers automatically.

The workspace AI agent can reply to customers on its own, grounded in your [knowledge base](/guide/knowledge-base). It works across channels and hands off to a human whenever a teammate takes over.

Configure AI under **Settings → AI**.

<Info>
  AI replies require the Pro plan and an active AI configuration. They stay off
  until enabled.

## Reply modes

Choose how the AI engages with new conversations:

* **Reply to all** — the AI answers unassigned conversations automatically.
* **Flows only** — the AI replies only where a [flow](/guide/flows) calls an AI response node, leaving first contact to your flows.

A conversation assigned to a specific teammate is never auto-answered — the AI steps back as soon as a human owns the thread. You can also assign a conversation directly to the AI agent to have it reply regardless of mode.

## Instructions and tone

Set custom instructions to shape how the AI answers — its role, tone, and any rules it should follow. Adjust the model and creativity (temperature) to fit your support style.

## Grounding in your content

AI replies use your [knowledge base](/guide/knowledge-base) to answer from your own documentation and website content, rather than guessing. Add sources there to improve answer quality.

## Usage limits

AI replies are metered against a monthly allowance for your workspace. When the allowance is reached, automatic replies pause until the next period.
