input: Write a function to create an AI-based chatbot in Python that can answer simple queries about a product or service. The function should include a dictionary of predefined answers and use them to respond to the user's queries. If a query is not recognized, the function should return a randomly chosen fallback response. Start the conversation with a welcome message and keep looping until the user types 'Goodbye' to end the conversation.
