# Auto-update

> Keep website sources fresh on a schedule so the agent stays current as your site changes.

Your site changes. Prices move, pages get rewritten, products come and go. Auto-update re-fetches your website sources on a schedule so the agent does not fall behind.

You control it from the **Refresh** dropdown in the Knowledge toolbar.

## Two things live here

* **Re-index all now** re-fetches every website source immediately. Use it after a big site update when you do not want to wait for the schedule.
* **Auto-update websites** sets a recurring schedule: **Off**, **Weekly**, or **Daily**.

Auto-update applies to website sources only. Files, text, and quick answers never change on their own, so there is nothing to refresh.

## What a refresh does

On each run we re-fetch your website sources and compare them to what we already have. Pages that have not changed are skipped, so a refresh is cheap and does not re-process unchanged content. Pages that changed are re-indexed. If a page fails to load, we keep the existing version rather than deleting it, so a temporary outage never wipes your knowledge.

The toolbar shows when the agent was last refreshed.

## Plan limits

Auto-update cadence depends on your plan:

| Cadence | Available on     |
| ------- | ---------------- |
| Off     | Every plan       |
| Weekly  | Growth and above |
| Daily   | Scale and above  |

If your plan does not include a cadence, the option is shown but locked with the plan you would need. Downgrading does not clear a schedule you set earlier; it just pauses until you are back on a plan that allows it. See [Plans](/docs/billing/plans).
