Udemy – AI Chatbots with Python, LangChain, LangSmith & Streamlit

In this hands-on masterclass, you’ll learn how to design, build real-world AI chatbots using Python, LangChain, Streamlit, and modern LLM platforms like OpenAI and Ollama. Whether you’re a developer, data scientist, or AI enthusiast—this course will teach you everything you need to create production-ready AI assistants from scratch.

You’ll go far beyond the basics. By the end, you’ll have built a full-stack chatbot with memory, LLM switching, persistent conversation history and LangSmith-powered observability and debugging.
