On Udemy

About this course

Build Real AI Applications with LangChain — Not Just TheoryStop watching AI tutorials that only explain concepts.

In this course, you will build real AI applications step-by-step using LangChain, including chatbots, RAG systems, and data-driven AI tools that actually work in real-world scenarios.

Whether you’re a beginner or someone already exploring Generative AI, this course will take you from zero → building production-ready AI applications using modern tools like vector databases, embeddings, and LLMs.

What You’ll Build in This Course

By the end of this course, you will be able to:

  • Build AI-powered applications using LangChain from scratch
  • Create intelligent chatbots that understand and respond using your own data
  • Design and implement complete RAG (Retrieval-Augmented Generation) pipelines
  • Work with vector databases like FAISS and Pinecone for fast data retrieval
  • Process real-world data (PDFs, websites, text files) using document loaders
  • Create embeddings using Hugging Face and Ollama
  • Use prompt templates, chaining, and output parsers (JSON, Pydantic)Build a real-world AI project with a Streamlit interface

Why This Course is Different

Most courses either focus on theory or show disconnected examples. - This course is designed for real-world execution

No unnecessary theory — only what you need

Step-by-step implementation with clear explanations

Learn by building, not just watching

Covers both fundamentals and advanced concepts in a simple way

What Makes This Course Powerful

You are not just learning LangChain.

You are learning how to:

  • Connect LLMs with real-world data
  • Build systems similar to ChatGPT
