Introduction to LangChain
Getting Started with LLM-Powered Applications
Join us for a 90-minute beginner-friendly introduction to LangChain. Understand the basics of building applications using Large Language Models, and see a simple LLM-powered application built through a live demonstration.
Why Learn About LangChain?
Generative AI and Large Language Models are changing how applications are built. But building an application around an LLM involves more than simply sending a question to an AI model. LangChain provides building blocks for working with models, prompts, tools and application logic, helping developers move from isolated AI interactions toward structured LLM-powered applications and workflows.
From Using AI to Building with AI
The shift is simple: instead of only asking an AI tool a question, developers can start designing an application around the model — with reusable prompts, defined steps and connections to other capabilities.
Connect
Bring models, prompts and application logic together.
Structure
Turn individual AI interactions into repeatable workflows.
Extend
Connect applications with tools such as APIs, search or databases.
Build
Create a foundation for useful LLM-powered applications.
LangChain in Simple Words
- LangChain is a framework for building applications powered by language models.
- It helps developers connect LLMs with prompts, application logic and other capabilities.
- It can be used to create different types of AI-powered applications.
- It is useful for developers who want to move from simply using AI tools to building applications with LLMs.
What You’ll Learn in 90 Minutes
- What is Generative AI? What is an LLM?
- How do LLM-powered applications work? Examples of LLM applications
- What is LangChain? Why is LangChain useful?
- Where does LangChain fit into an AI application?
- Models, Prompts, and Chains — explained simply
- What are prompt templates? Why are reusable prompts useful? Simple examples
- What is a chain? How can multiple AI steps be connected? Simple workflow examples
- What are tools? Why might an AI application need tools? Simple examples: calculators, search, APIs, databases

Build a Simple LLM-Powered Application
The trainer will build a simple AI Content Assistant during the webinar — showing how a user input can move through a prompt, LangChain and an LLM to produce a useful response.
Example Topic
“Benefits of AI in Corporate Training”
No complicated project. No advanced architecture. The goal is to make the core idea easy to see and understand.
Make Your Prompts Reusable
Prompt templates allow developers to create reusable instructions rather than writing a completely new prompt every time.
A simple prompt template example:
Audience: {audience}
Tone: {tone}
Connect Multiple AI Steps
A chain allows multiple steps to be connected into a workflow.
What If the AI Needs More Than Its Own Knowledge?
Applications can sometimes connect an LLM with external tools — such as a calculator, search, database, or API.
Who Should Attend
No prior LangChain experience required. Basic programming/Python knowledge is helpful, but the session is designed to be accessible to beginners.
By the End of the Webinar, You’ll Understand

- What LangChain is
- Why developers use LangChain
- What models, prompts and chains mean
- How prompt templates work
- How simple AI workflows can be connected
- What tools are and why AI applications may use them
- Where LangChain can be used
