Embedded programs and interfaces for chat conversations

A computer-implemented method to provide an embedded application in association with a messaging application, the computer-implemented method comprising:

• causing a first embedded application to be initiated on a first user device in association with a first chat interface displayed by a first messaging application that executes at least in part on the first user device, wherein the first chat interface is configured to display messages from the first user device and messages from a second user device that communicates with the first user device via a chat conversation over a network;
• determining that the second user device is included in an embedded session associated with the first embedded application;
• causing, via the first messaging application, the first embedded application to connect to the embedded session, wherein the first user device and the second user device are enabled to communicate with each other within the embedded session, and the embedded session is updated based on data received from the first user device and the second user device;
• causing output of a first content item in a first embedded interface of the first embedded application on the first user device;
• determining that a second content item is currently displayed on a third user device not communicating in the chat conversation and that the second content item has a same title as the first content item currently being output in the first embedded interface of the first embedded application on the first user device;
• and
• in response to determining that the second content item has the same title as the first content item, causing the third user device to be connected to the embedded session.
