The document describes a pet recommender chatbot application that uses Python code and three AI models. The Python code asks the user questions about their preferences and sends the answers to the AI models. One AI model determines if the user wants a dog or cat. The other two AI models then provide breed recommendations based on the user's preferences. The developer trained the AI models using a Google spreadsheet containing possible values for each breed. Going forward, the developer wants to expand the application by adding more pets, breeds, and attributes like color.
