AI Chatbot Stack

An AI chatbot stack is a software architecture that enables conversational interaction between users and artificial intelligence systems through natural language interfaces. These architectures coordinate user interaction, language model inference, memory, retrieval, orchestration, and external services to deliver responsive and context-aware conversations. They support customer assistance, educational platforms, enterprise knowledge systems, coding assistants, operational copilots, and conversational AI applications.
