Chatbots should do more than just chat.
We just published a new course on the freeCodeCamp.org YouTube channel that will teach you how to build a smart AI shopping assistant from the ground up.
This comprehensive course, created by Ania Kubow, goes beyond typical chatbot tutorials. You will create a powerful AI agent that thinks and acts like a real sales associate, capable of making its own decisions to help customers.
This AI agent can:
-
Autonomously decide when to search a database versus when to respond directly.
-
Use custom tools to search through real product information.
-
Remember past parts of the conversation.
-
Take multi-step actions to perceive, plan, act, and respond to a customer.
Throughout the course, you will work with modern, cutting-edge technologies. You’ll use LangGraph for agent orchestration, MongoDB Atlas for vector search and memory, and Google’s Gemini to power the AI’s brain. Ania explains everything step-by-step, so you don’t need to be an expert in these tools to get started.
By the time you finish, you will have built a complete project with three parts: a Node.js backend, a MongoDB database with AI-generated product data, and a user-friendly React frontend.
Watch the full course on the freeCodeCamp.org YouTube channel (2-hour watch).
