Steps to Get API Key

To use the ChatGPT API, we need to create an account with OpenAI and generate an API key. If you have already used ChatGPT, you already have an account.

Note: You can skip this step if you already have an account.

• Head over to their official website and click on Signup.
• Signup using an email address or social accounts like Google, Microsoft, and Apple
• Fill up some basic details like Name, Birthdate, etc., and verify your mobile number.

Voila! you now have a brand new ChatGPT account to proceed with.

Generate API Key

Login to your account and head over to the OpenAI Platform.

In the top right corner of the screen, click on your account name and then select “API Keys” from the drop-down menu.

On the API Keys page, click the “Create new secret key” button, name your key (optional), and click on “Create secret key” to get your brand new key. Now copy the key and save it anywhere which we later need in this project.

A ChatBot is a computer program that uses Artificial Intelligence (AI) and Natural Language Processing (NLP) to understand customers’ questions and give responses to them simulating human behavior. Building our own ChatBot from scratch requires us to train the Machine Learning (ML) model with rigorous amounts of text-based data, providing it with different contexts of real-world conversations. Now we don’t need to perform that meticulous task, as OpenAI already developed ChatGPT which was trained on billions of words of textual data which made it very powerful.

In this article, we will explain the total process of building a Mobile ChatBot Application using ChatGPT API and Flutter. We will be using Flutter Framework to build the application for Android. Flutter is an open-source framework developed and supported by Google to build and deploy hybrid applications quickly.

A sample video is given below to get an idea about what we are going to do in this article.
