Build a Modern AI Chatbot: Rasa vs. LangChain (Intent, Entity & LLM RAG Tutorial)

Description

Chatbots are everywhere! This video gives you the complete guide to building intelligent conversational agents, from understanding the core mechanics to using state-of-the-art Large Language Models (LLMs). We break down the essential components that make a bot smart: Rule-Based vs. AI-Based: The critical difference in design and flexibility. Intent Detection: How the bot figures out what the user wants ("I want to order a pizza"). Entity Extraction: How the bot captures the details it needs ("pepperoni," "large," "delivery"). Then, we get hands-on with a full comparison of two powerful frameworks: Rasa: The gold standard for traditional, custom, and highly controlled NLP chatbots. LangChain: The modern way to leverage LLMs and RAG (Retrieval-Augmented Generation) for incredibly flexible, powerful conversational AI. Learn the code, understand the trade-offs, and master the technology to build your own customer support, e-commerce, or personal assistant bot! #Chatbot #NLP #Rasa #LangChain #LLM #AITutorial #Python #MachineLearning #DeepLearning
