# Add YouTube videos

Add YouTube videos or playlists so your bot can answer questions from what's said in them, such as tutorials, webinars and product walkthroughs.

**Who can do this:** [team owners and admins](https://chatthing.ai/docs/account/teams#what-each-role-can-do).

> **Captions required**
>
> Chat Thing reads each video's **English captions**. Videos without English captions are added but have no content. Auto-generated captions work; captions you've uploaded or corrected are more accurate.

## Steps

1. Open your bot, go to the **Data sources** tab and click **New data source**.
2. Choose **YouTube** and click **Create data source**.

3. On the **Content** tab, click one of these buttons (on a small screen, they're under **Add**):
   - **A single URL**: paste the address of one video or playlist.
   - **Add bulk URLs**: paste several video or playlist addresses, one per line.

4. Click **Add**.
   ![The Add multiple videos & playlists dialog with a playlist URL and a video URL on separate lines](https://res.cloudinary.com/djyjvrw5u/image/upload/v1721392501/youtube_add_multiple_31bf8da11e.png)
5. Click **Synchronise**.
   ![A YouTube video and a playlist listed as Not synced on the Content tab, ready to synchronise](https://res.cloudinary.com/djyjvrw5u/image/upload/v1721392502/youtube_sync_e676a09b75.png)

Adding a playlist adds every video in it. Each sync checks the playlist again: videos added to it since the last sync are added, and videos removed from it are removed from your bot.

## Check it works

1. After the sync, check each video's **Storage tokens** column. A video with no storage tokens had no English captions.
2. Ask your bot a question that one of the videos answers.

## Troubleshooting

### A video has no content after syncing

The video has no English captions, or captions are turned off. Add or enable English captions in YouTube Studio, then sync again.
