Build a Chatbot with OpenAI GPT Using Flask: Python AI Web

In this course, you will build a fully functional AI chatbot from scratch using Python and Flask.

Instead of just calling an API, you will understand how everything connects together. You’ll start by setting up your development environment and building a simple Flask web application. Then you’ll create a clean chat interface using HTML and CSS.

After that, you’ll use JavaScript to handle user input and communicate with your Flask backend. Finally, you’ll connect your app to the OpenAI GPT API and generate real AI responses inside your chatbot.

By the end of this course, you’ll have a working AI-powered web application and a clear understanding of how frontend, backend, and AI services integrate in a real-world project.

This is perfect if you want to move from just “using AI tools” to actually building AI applications.
