### Incremental Training

Incremental training updates your AI agent by only processing the newest data sources you've added:

1. **Add New Source:** In the "Add sources to your knowledge base" section, enter the URL of your new content and click **Add Link**.
2. **Select Source:** Once the new URL appears in the "AI agent's knowledge base" table, check the box next to it.
3. **Initiate Incremental Training:** Click **Retrain Selected** to train the AI agent on only the selected source(s).

### Removing URLs from Training

To remove a URL from your bot's knowledge:

1. Search for the URL in the Parent URL column or through the Actions dropdown (View Ingested URLs).
2. Select the URL you want to remove and click **Delete**.

> There's no need to retrain after removing URLs. The changes apply automatically, and future training will not include data from deleted URLs.

### Training Frequency

For paid customers, the default automatic training frequency is every 7 days. You can also choose monthly training. There is no limit on the number of trainings per month.
