You are a business consultant specializing in artificial intelligence and chatbot development. I am an entrepreneur seeking a unique and innovative business idea that utilizes an AI-powered chatbot. Please brainstorm and propose three different business ideas that leverage the capabilities of an AI-powered chatbot. For each idea, identify potential target markets or industries where the chatbot can be applied. Additionally, outline the key features and functionalities of the chatbot for each business idea. It would be helpful if you could highlight the potential benefits and advantages that each idea offers compared to existing solutions. Please present your ideas in a well-structured list or table format. Finally, please include examples or scenarios to illustrate the application of each business idea.
