# Manage your knowledge sources

Your AI agent answers from the sources you add: website pages, files and Google Docs or Sheets. You
see them all on the **Data sources** page (sidebar: **Data Sources**).

## Find a source

* **Type tabs:** **All**, plus one tab with a count for each type you've added, such as **Website**,
  **Files** or **Google Drive**.
* **Search by name or address:** matches a source's name or web address.
* **Status:** show **Any status**, or only **Ready**, **Training**, **Queued** or **Failed** sources.

## What each row shows

* The type (**Website**, **File**, **Google Drive**, **Google Docs** or **Google Sheets**) and the
  source's name.
* Its web address, or for a file its size.
* When it was last updated.
* Its status:
  * **Ready:** the agent can answer from it.
  * **Training:** the agent is still learning from it.
  * **Queued:** it will start shortly.
  * **Failed:** something went wrong. The reason shows under the status. Try **Retrain**, or remove
    the source and add it again.

## Actions on a source

* **View content:** read the text the agent uses from this source. See [Chunks](/knowledge/chunking).
* **Retrain:** read the page or Google file again. Uploaded files can't be retrained. See
  [Retrain and remove](/knowledge/resync-and-delete).
* **Remove:** remove the source after you confirm. The agent stops answering from it.

You see **Retrain** and **Remove** only if your role can change knowledge sources.

To add a source, click **Train AI agent**. See [Train your AI agent](/knowledge/ingestion-methods).

## Limits

The All-In-One Pro Plan includes up to 500 sources. On the Free plan, a website crawl is limited to 5
pages. See [Plan and usage limits](/billing/credits).
