LangChain Framework for Beginners – Build AI Systems + RAG | Udemy

If you’ve been hearing words like “AI Agents”, “LangChain”, or “RAG” everywhere and wondering how people are building smart AI apps that can search data, answer questions, or take actions on their own — you’re in the right place.

This beginner-friendly course will show you how to build real AI applications from scratch, even if you have never worked with AI before.

Most people only use ChatGPT to write text…
But companies today are building applications that can think, read, search, decide, and act automatically.

These applications are powered by LangChain — the leading framework for building AI-powered software.

In this course, you will learn how to:

• Build simple AI apps that actually do useful tasks
• Make an AI use tools (like checking the weather or sending an email)
• Let an AI read documents and give answers based on your data
• Organize information so the AI can “remember” things
• Build small automation systems that can save time and effort

We will start from zero, explain every concept in plain English, and build everything step-by-step together.

By the end of the course, you will be able to build your own AI apps that can be used for:

• Personal projects
• Business automation
• Customer support
• Data lookup
• Testing and QA
• Real-world workflows

No complex math
No advanced AI background
No prior LangChain knowledge required.

Just practical learning, short lessons, real projects, and the confidence to build your own AI applications.

If you want simple, hands-on learning that focuses on doing — not theory — this course is perfect for you.
