Build a Multi-Personality AI Chatbot: React & OpenAI API Tutorial (System Roles & Message History)
Learn how to build a dynamic AI Chatbot that can take on different personalities (Bill Gates, Steve Jobs, Albert Einstein) using React and the OpenAI Chat Completions API. In this tutorial, we cover how to implement "System Roles" to define personas and how to manage a persistent message array in React to maintain conversation context.
What You’ll Learn:
Setting up a React front-end with a flexible chat UI.
Using the system role in OpenAI to create AI personas.
Managing a messages array state to keep conversation history.
Building a Node.js/Express backend to handle API requests securely.
Using Axios for front-end to back-end communication.
