Live chat basics

Live chat is enabled by default and will appear to the right of the video player only when your event is active. The Live chat module only exists on the YouTube watch pages — it does not follow embedded players. Watch the video demo

Live chat badges identify the Streamer  and Moderator .  Click on the expandable area below for more information on moderators.

Viewers are limited to 200 characters and a maximum of 3 submissions every 30 seconds. Event owners are not subject to the frequency threshold. Viewers cannot post special characters, URLs or HTML tags.

You can review chat activity in YouTube Analytics. The "Comments" metric is for live and on demand.

Manage Live chats

Use the menu chat dots to pop out live chat in a new window for easy moderation or see a list of active chat users from the last 5 minutes.
Moderate Live chat

You can assign moderators for all live chat sessions. Moderators remain on the list until they are unassigned.

We strongly recommend that you have at least one dedicated live chat moderator for high-traffic events. Moderators can interact with the audience and remove comments when appropriate.  They can also flag, block or put users in time out.  

Assign moderators

Select menu chat dots next to username in chat and select Set User as Moderator or follow these instructions:

  1. Click the three dots (...) next to the chat text box.
  2. Enter a username.
  3. Set up one list of moderators for your channel. Moderators remain on the list until they are unassigned.

Manage spam messages

Select the checkbox for Automatically block spam messages checkbox. This blocks simple spam such as long messages in all caps or repeated identical messages by the same user.  

Block words proactively

  • Compile blocked words in the Community Settings section.  Live chats matching these words will be blocked.  
  • You can also block links from being used in comments by typing "*links*" into the Blocked words field.

Block a viewer from live chat

Select menu chat dots next to the chat message and select Block User or follow these instructions:

  1. Go to the viewer's YouTube channel.
  2. Click the About tab.
  3. Click on the flag and select Block.

Note: This will also block the user from the comments. Users you have blocked will be visible in Hidden Users in Community Settings. 

Unblock a viewer from live chat

To remove block status:

  1. Go to the viewer's YouTube channel.
  2. Click the About tab.
  3. Click on the flag and select Unblock.

Note: Once a user's block status has been removed, they will once again be able to leave comments and live chat messages on your channel.

Embed Live chat

During a live stream, you can embed live chat on your own side by using an iframe.

  1. Get the video ID for the live stream. You can get the video ID from the watch page URL ( In this case, the video ID is ‘12345’.
    • If you chose "Stream now," right-click on the player and select Copy video URL to get the video URL.
  2. Get the domain URL for the site you want to embed chat on. If you're embedding chat on, your embedding domain is ""
  3. Combine the embedded URL in the following way:
  4. This is the URL for your iframe. Note the embed_domain must match the the URL of the page you’re embedding the chat on. If they are different, the embedded chat will not load.
Disable Live chat
