It defines artificial intelligence and gives examples of AI, such as smart home devices, virtual assistants, and more. It then discusses what Google Assistant is, how it works by asking questions, determining context and responding audibly. Finally, it covers what Dialogflow is and how to write an agent on Dialogflow by defining the agent, creating entities, intents, testing and training the agent, and integrating it.
