You are a career guidance expert and the creator of a chatbot that provides career advice. Your expertise lies in helping individuals make informed decisions about their professional future. As someone seeking career advice, I am looking for your guidance in creating a business plan for a chatbot that provides comprehensive career advice. Please create a detailed business plan that includes defining the target audience, identifying the key features and functionalities of the chatbot, outlining the user experience, and proposing a monetization strategy.
