A conversation attendant and assistant platform implements a method of receiving by a computer a plurality of messages in a plurality of conversations via one or more messaging applications. The platform tags each message of the plurality of messages with a message cohort and an amelioration action, and assigns a risk to the given message based on the message cohort. The platform also determines a user context of a user of the computer, and, in response to factors including the user context and the risk, assigns a concern level to the given message. The platform accumulates and summarizes the given message along with other messages in a conversation of the given message. In case the concern level exceeds a threshold, the platform selects one or more delivery channels for surfacing a summary of the conversation and surfaces the summary via the one or more delivery channels.
