Build an AI Chatbot
Chatbots are the most-requested AI feature — and the most often done badly. This course teaches you to build one that is actually useful: a chatbot with a knowledge base, streaming responses, conversation memory, and tool use. You will build a working chatbot by lesson 3 and progressively harden it into something production-ready by lesson 8.
