CarTrends-Chatbot: A Generative AI-Powered WhatsApp Intelligent Sales Assistant

CarTrends-Chatbot is a WhatsApp intelligent sales assistant built using generative AI technology. It aims to address the limitations of traditional chatbots in handling complex sales scenarios and achieve end-to-end sales automation from customer inquiries to order placement. The project uses a tech stack including Python, Streamlit, and the Ollama API, integrating AI capabilities into the user-familiar WhatsApp channel to enhance sales efficiency and customer experience.
