Build an AI Agent with LangChain: Step-by-Step Guide

Learn to create real-world AI agents using LangChain, OpenAI, and Python—no prior AI experience required!

What you'll learn
- Understand the fundamentals of Artificial Intelligence (AI) and how it differs from traditional software systems.
- Differentiate between AI agents and chatbots, and identify when to use each in real-world applications
- Recognize real-world use cases of AI agents across industries like customer service, automation, and research.
- Install and configure Python properly on their system for AI and LangChain development.
- Create and activate a Python virtual environment to manage project dependencies effectively.
- Set up essential developer tools such as Visual Studio Code, pip, and API keys (OpenAI, SerpAPI).
- Securely store and manage API credentials using environment variables and .env files.
- Verify successful API connections and ensure that LangChain, OpenAI, and other packages work together seamlessly.
- Understand the LangChain architecture and its core components: Models, Prompts, Chains, and Agents.
- Differentiate between Chains and Agents in LangChain, understanding their workflows and use cases
- Create and customize prompt templates to guide AI model responses more effectively.
- Build custom LangChain tools that extend the functionality of AI agents for various tasks.
- Develop and test a working AI agent that can perform automated reasoning or data retrieval using multiple tools.
- Apply best practices for debugging, scaling, and enhancing AI agents for real-world projects or personal experimentation.

Requirements
- Basic computer skills – comfortable with installing software and using the command line (terminal).
- A computer with internet access – Windows, macOS, or Linux (any modern machine works).
- Python installed (you’ll learn how to set it up during the course).
- A text editor or IDE – we’ll use Visual Studio Code (installation covered in the course).
- An OpenAI account – required to access the GPT API (setup shown step-by-step).
- A SerpAPI account – for enabling web search capabilities in your AI agent (setup also covered).
- Curiosity and enthusiasm – no prior AI or coding experience is required!

Description
Artificial Intelligence is transforming the world — andAI agentsare at the heart of that revolution. From virtual assistants and research bots to automated problem-solvers, agents are the next leap beyond simple chatbots. In this hands-on course, you’lllearn step-by-step how to build your own working AI agentusingLangChain,Python, and theOpenAI API— no advanced technical experience required.

We’ll start from the very beginning. You’ll understand what AI really means, how agents differ from chatbots, and where they’re being used in the real world. Then, you’ll dive into the practical side — setting up your Python environment, installing key tools, and connecting APIs likeOpenAIandSerpAPIto bring intelligence and search power to your creations.

Once your setup is complete, we’ll explore thecore concepts of LangChain— including chains, agents, prompts, and tools. You’ll learn how to create prompt templates, build your own tools, and finally, connect them all to create an AI agent that can think, search, and respond intelligently. By the end, you’ll not only understandhow LangChain works, but also how tobuild, test, and customize your own AI-powered assistantsfor real-world use.

Whether you’re an aspiring developer, a curious beginner, or an entrepreneur exploring the future of automation, this course gives you the practical foundation you need to start building with confidence.
