Various embodiments relate generally to data science and data analysis, computer software and systems, and wired and wireless network communications to interface among repositories of disparate data and computing machine-based entities configured to access, track, and/or analyze data, and, more specifically, to a computing and data storage platform to implement computerized tools to continuously (or nearly continuously) sense data describing functional states of remote computing devices and/or user interfaces configured to service electronic messages, according to at least some examples. For example, a method may include receiving a stream of data representing states of user interfaces, analyzing the states of the user interfaces, identifying activity data, identifying a state of an application, detecting an action and classifying a subset of activity data based on the action, and generating data representing a state of an application configured to interact with a digital conversation.
