Build real AI apps from scratch – ChatGPT clone, RAG chatbot, email classifier & more with OpenAI’s TypeScript SDK

What you’ll learn
Connect to OpenAI APIs using TypeScript and Node.js to build real AI-powered applications from basic responses to advanced function calling
Build a terminal ChatGPT clone with real-time streaming responses that works exactly like the ChatGPT interface you already know and use
Create RAG applications that let users chat with custom documents and data files, dramatically improving AI usefulness for specific domains
Implement function calling to let AI trigger real actions in your apps – users describe what they want in plain language, AI executes the code

Requirements
Basic TypeScript knowledge

Description
Most developers think AI integration is complicated. It’s not. You just need to know how to connect to the right APIs.In this hands-on course, you’ll build multiple working AI applications using TypeScript, Node.js, and the OpenAI SDK. No theory lectures – just real code you can use immediately.What You’ll Build:Terminal ChatGPT Clone – Stream AI responses in real-time, just like the real thingEmail Classifier – Analyze sentiment and return structured JSON data for your appsRAG Knowledge Chat – Let users chat with your custom documents and data filesFunction Calling App – AI that can trigger real actions in your applicationPlus foundational examples – Basic responses, streaming, and structured outputWhat Makes This Different:I’ve taught almost 80,000 developers on Udemy. I don’t waste your time with endless theory or marketing fluff. You’ll see working code from minute one.Each example builds practical skills you can apply immediately. The entire development and testing for this course cost me 22 cents in API calls – so you’re not looking at expensive experimentation.What You Need:Basic TypeScript knowledgeNode.js installedOpenAI API account (I’ll show you how to set this up)That’s itWhat You Get:Multiple complete, working AI applicationsAll source code included with every lessonStep-by-step setup and implementationReal-world patterns you can use in any TypeScript projectWhy TypeScript?Because it works everywhere – Next.js, React, Node.js backends, whatever you’re building. Learn once, use everywhere.No previous AI experience required. Just bring your TypeScript skills and let’s build something useful.Stop wondering how AI integration works. Start building it.
