title: "Retraining Knowledge"
description: "Keep your agent up to date by retraining its sources when your website or documents change, manually or automatically."
---

Your agent learns from a copy of your content made when the source was trained. If the original changes, such as an updated pricing page, retrain the source so your agent has the latest version.

## Retrain everything

In your agent, go to **Build** > **Knowledge** and select **Retrain Agent** in the **Knowledge base** panel. Every source is reprocessed. While it runs, the button shows **Training in progress...**.

## Retrain some sources

In the **Sources** list, select the sources you want, then choose **Bulk actions → Retrain selected**.

## Retrain automatically

Turn on **Auto-retrain** to have Chatvox check your sources for updates every 24 hours.

1. **Open training settings**

    In your agent, go to **Settings** and scroll to the **Training** section.

2. **Turn on Auto-retrain**

    Switch on **Auto-retrain**. The **Last trained at** field shows when your agent was last trained.

:::note
New sources are trained automatically when you add them. You don't need to retrain after adding something new.
