# Knowledge

Train the AI agent on the content it uses to generate replies. Training sources are separate from the agent's persona and behaviour — those are configured in the **Agent** tab. See [Manage AI agents](/docs/modules/ai-agents/manage-ai-agents.md).

## Add a training source

Select one of the three buttons at the top of the Knowledge base table.

{% tabs %}
{% tab title="Upload file" %}
Supported file types: csv, json, pdf · Maximum file size: 5 MB

1. Select **Upload file**.
2. Enter a **Name** for the source.
3. Drag and drop a file or select **Browse files**.
4. Select **Train**.
   {% endtab %}

{% tab title="Add URL" %}

1. Select **Add URL**.
2. Enter a **Name** and the full URL (must start with `https://`).
3. Choose the scope: **URL webpage** trains only on the page at that URL. **All webpages** crawls and trains on all pages linked from that URL.
4. Optionally enable **Automatically retrain every** and select an interval: 12 hours, 1 day, 1 week, or 1 month.
5. Select **Train**.
   {% endtab %}

{% tab title="Paste snippet" %}

## Manage training sources

The knowledge base table lists all sources with name, last updated date, and status. Filter by **Search**, **Type**, and **Status**.

| Status  | Meaning                                |
| ------- | -------------------------------------- |
| Pending | Queued for training                    |
| Loading | Training in progress                   |
| Success | Trained and active                     |
| Fail    | Training failed — remove and try again |

To delete a source, select its row and use the delete option.
