Most importantly, a willingness to learn by building real-world AI applications
Description
Learn to build Agentic AI applications with LangGraph-from intelligent chatbots and Human-in-the-Loop workflows to advanced Multi-Agent AI Systems.
Large Language Models can generate impressive responses, but building
real-world AI applications requires much more than sending prompts to an LLM.
Modern AI systems need
state, memory, decision-making, routing, tool usage, streaming, human approval, and reliable execution.
That's where
LangGraph comes in.
In this hands-on course, you will learn how to use
LangGraph and Python to design and build stateful AI workflows, conversational agents, Human-in-the-Loop systems, and multi-agent architectures.
You won't just learn the concepts.
You will build complete AI applications from the ground up.
Build 7 Practical Agentic AI Applications
Throughout the course, you will progressively build real projects that put each concept into practice
AI Blog Generator - Build a multi-step AI workflow using LangGraph.
AI Shopping Recommendation System - Create a personalized recommendation workflow with conditional routing.
Conversational AI Chatbot - Build a multi-turn chatbot with message-based state, conversation history, threads, and persistent memory.
Streaming AI Application - Stream LangGraph and chatbot responses as they are generated.
Human-in-the-Loop AI Workflow - Build an AI workflow that can pause, request human approval, and resume execution based on human feedback.
AI Coding Tutor - Build an AI tutor that generates, streams, and saves coding lessons.
Multi-Agent Research Assistant - Build an advanced multi-agent system with specialist agents for
weather, research/arXiv, and CSV data, connected through intelligent intent-based routing.
Master the LangGraph Architecture
You will begin with the fundamentals and learn the core building blocks behind LangGraph applications
State → Functions → Nodes → Edges → Conditional Routing → Graph Execution
You will learn how information flows through a graph, how nodes perform individual tasks, how edges control execution, and how conditional routing enables dynamic AI workflows.
By the end of this foundation, you will be able to independently design and build your own LangGraph workflows.
Build Stateful Conversational AI Chatbots
Go beyond simple prompt-and-response applications and learn how to build
multi-turn conversational AI systems.
You will work with message-based state, conversation history, threads, and checkpointers to create chatbots that can
maintain and resume previous conversations.
You will also learn how to add
streaming so your applications can deliver responses progressively rather than waiting for the entire workflow to finish.
Build Human-in-the-Loop AI Systems
Not every AI decision should happen completely autonomously.
You will learn how to build
Human-in-the-Loop workflows where an AI application can pause execution, request human approval or feedback, update its state, and then continue or reject the workflow.
This gives you a practical understanding of how human oversight can be incorporated into Agentic AI workflows.
Build More Reliable AI Workflows
Building an agent is only the beginning.
You will also learn practical techniques for making LangGraph applications
more reliable and easier to debug, including retries, regeneration of weak outputs, iterative workflows, graph visualization, routing inspection, and common graph design mistakes.
Build an Advanced Multi-Agent AI System
The course culminates in an advanced
Multi-Agent Research Assistant.
You will build an architecture where different specialist agents handle different types of requests.
The system will include
Intent Classification
Intelligent Routing
Weather Agent
Research/arXiv Agent
CSV Data Agent
Conditional Graph Branches
Unified Final Response
Graph Visualization and Debugging
You will see how multiple specialized agents can work together within a single LangGraph architecture to handle different real-world tasks.
