Techniques for determining and/or displaying summarized messages are discussed herein. A user may post a message to a virtual space of a communication platform. That is, a user may send a message to one or more users via a virtual space. In such instances, the communication platform may identify the intended recipients of the message and input the message and the intended recipients into a machine-learning model to receive, as output from the machine-learning model, data indicative of a summarized representation of the message. The summary may include information that is relevant and/or important for the intended recipient user(s). Further, the summary may include a summary of the message, action items included in the message, recommendations, and/or any other information. In some examples, the communication platform may cause the summary to be displayed via a user interface of the recipient user.
