yChat

1. In OBS, click + under Sources and choose Browser. In Streamlabs it is Browser Source.
2. Paste the link into URL. Set the width and height to the area you want chat in, for example 500 × 900.
3. That's it. Keep it in your scene: it connects when you go live and waits quietly when you're not.

Want to place it before you go live? Open the test version: same look, with made-up messages.
