A method includes capturing an event, analyzing the event to generate graphs, receiving a natural language utterance, identifying an entity and a command, modifying the graphs; and emitting an application prototype. An application prototyping server includes a processor; and a memory storing instructions that, when executed by the processor, cause the server to capture an event, analyze the captured event to generate graphs, receive a natural language utterance, identify an entity and a command, modify the graphs; and emit an application prototype. A non-transitory computer readable medium containing program instructions that when executed, cause a computer to: capture an event, analyze the captured event to generate graphs, receive a natural language utterance, identify an entity and a command, modify the graphs; and emit an application prototype.
