About
The Chat and Collaboration (C&C) feature brings interactivity to live webcasts and Kaltura Room sessions. Attendees can join the conversation through real-time chat, polls, quizzes, and Q&A, making sessions more dynamic and engaging. The features available will depend on how the moderator has configured the session.
Access the Chat & Collaboration functions
Desktop
The Chat & Collaboration menu is located on the right sidebar in desktop. It contains tabs for Updates and Live Stage. Click the expand button (arrow icon) in the upper right corner of the screen.
Mobile
On mobile devices, the Chat & Collaboration (C&C) panel appears at the bottom of the screen and opens automatically (it cannot be collapsed).
Mobile note: All features (Chat, Q&A, Feed) are accessible, but layouts may be more compact to fit smaller screens.
When viewing the C&C features, the stage is hidden until you close the C&C panel.
Updates
The Updates tab displays the notifications sent from the moderator to all participants during the session.
The following shows the Updates tab with a small toast popup in the lower left corner of the screen.
Live Stage
The Live Stage tab includes sub-tabs for Chat, Q&A, and Feed.
Chat tab
This is the public group chat for the session. You can:
- Like a message: Hover over a message and click the Like icon.
- Reply to a message: Hover over a message and click the Reply icon.
- Delete your message: Hover over your message and click the Trashcan icon.
Q&A tab
Use the Q&A tab to ask moderators questions during the session. The experience may differ based on your system setup:
- Single thread (default): All your questions stay in one thread.
- Multi-thread: Each new question starts a separate thread, making it easier to manage different topics.


In this article, we'll demonstrate the multi-thread setup.
Asking your first question:
- Click the Ask new question button.
- Type your message and press Enter. A new conversation thread opens with your question at the top. The moderator will respond within the same thread.
The Write your message text field displays.
You can return to the list of threads any time by clicking the back arrow in the thread header. You can also reopen and continue any previous thread.
Starting a new question thread:
- Click the Ask new question button.
- Type your question in the Write your message field and press Enter. A new thread opens with your question at the top.

Click the desired option to enable it.
