OBS Browser Source

Stream chat with PluralChat

PluralChat includes an optional OBS Browser Source that lets you display Twitch chat with PluralChat member information directly on your stream.

How it works

The PluralChat OBS Overlay connects directly to Twitch chat and displays messages in real time.

When someone with a published PluralChat system sends a message, their member name, pronouns, avatar and colours are shown alongside their chat message. Messages from everyone else are displayed as standard Twitch chat, allowing PluralChat and regular chatters to appear together seamlessly.

Getting started

  1. Create an OBS Custom Browser Dock using:
    https://api.pluralchat.online/overlay/chat
  2. Sign in with Twitch when prompted.
  3. Enter the Twitch channel you want to join.
  4. Use the built-in chat box to send messages without leaving OBS.
  5. Click a username to open either the PluralChat member card or the Twitch moderation card.

Adding chat to your stream

Add a Browser Source to your OBS scene using:

https://api.pluralchat.online/overlay/chat?channel=ChannelNameHere&chatonly=1

Replace ChannelNameHere with your Twitch channel name. This displays a clean, read-only chat overlay with no controls, making it ideal for livestreams.

Privacy: When using the interactive OBS overlay, you sign in with Twitch so PluralChat can send chat messages and perform moderation actions on your behalf.

Your Twitch access and refresh tokens are stored only in the PluralChat server's memory (RAM) for the duration of your active session. They are never written to the database, configuration files or log files, and are automatically removed when you log out or the server is restarted.

PluralChat never stores your Twitch password.

Local storage

The PluralChat extension stores settings, setup progress, recovery keys and cached system data locally in your browser. The OBS Chat Dock may also remember the last Twitch channel you joined.
