Let us now understand how, with the help of ChatGPT integration, you can build an app for your business.

How to Build an App With ChatGPT?

To explain the process better, we will take an example of building a customer support app entirely with the help of ChatGPT for Android. No matter what industry your business belongs to, you will always need a robust customer support system that can quickly provide the perfect solutions.

Quality customer support services have become so important as 88% of customers are willing to purchase again from a company that provides good customer service.

How to Integrate ChatGPT into Your Website

Below are the steps to follow when building a customer support app for your business. Before you begin building the app, you must define the target audience and user personas for your app. It will enable you to understand in detail the app's functionality, features, and user interface.

1. Define the Use Case

Defining the use case is a crucial step in the process of building an app with ChatGPT. It includes the app's purpose, features, scope, scalability, privacy, and security. Now, when you are creating a customer support app, the use cases can defined as below:

Purpose: The purpose of your app can be to provide assistance and resolution to users' queries and issues through natural language interactions. It means that your customers should be able to communicate with the app using their everyday language.

Features: Another important factor is the features and functionalities of the customer support app. With the help of it, users will be able to get the perfect solution to their queries and complaints.

Some of the important features that you must add to the customer app are:

  • Ticket management
  • Live chat support
  • Knowledge base
  • Customer feedback and survey tools
  • Issue reporting
  • Natural language understanding
  • Self-service options

2. Choose an Integration Approach

Deciding on how to integrate ChatGPT into your customer support app is part of the "Choose an Integration Approach" process. You have two options: you may integrate the ChatGPT model directly into your app's front or backend. Alternatively, you can utilize OpenAI's hosted API, which allows your app to submit text inputs to OpenAI's servers for processing.

Because OpenAI handles the infrastructure and updates, using its hosted API is convenient and scalable. However, transmitting user data to OpenAI's servers may result in fees depending on use.

3. Add Open API Dependency

We are going to add the OpenAI API requirement to your Android project in this phase. This requirement makes it possible for your app to communicate with the OpenAI API, which is required in order to send and receive user messages to the GPT model.

To add the OpenAI API dependency, you need to modify your app's build.gradle file, which is typically found in the "app" module of your Android project.


4. Initialize OpenAI API

You must set up the OpenAI API using your API key in order to initialize it in your Android application. It typically includes passing your API key as an argument when implementing the OpenAI.configure() function.

Usually, your Application class's onCreate() function or another suitable initialization class handles this initialization phase. You may make sure that your application is authenticated to communicate with the OpenAI services throughout its lifespan and send and receive requests from the GPT model by setting the OpenAI API with your API key.

 Application class's onCreate()

5. Create Chat Activity Layout

Consider using elements like EditText for user input, a Button for sending messages, and a TextView or RecyclerView to show the conversation history when creating the layout for your Android app's chat activity. 

To specify how these elements will be arranged and shown in your activity:

  • Use XML layout files.
  • Make sure the layout makes sense, is aesthetically pleasing, and complements the branding of your app.
  • Adjust properties like font, color, size, and location to produce a unified user interface.
<LinearLayout xmlns:android=""


            android:padding="8dp" />


            android:hint="Type your message here"
            android:inputType="text" />

            android:text="Send" />


6. Implement Chat Functionality

In the "Implement Chat Functionality" step, you will develop code to manage user message transmission to the GPT model and response display. In order to do this, methods for sending user inputs to the OpenAI API for processing must be created. The resultant replies must then be updated in the user interface.

import com.openai.api.models.CompletionRequest;
import com.openai.api.models.CompletionResponse;

public class ChatActivity extends AppCompatActivity {
    private EditText userInputEditText;
    private TextView chatTextView;

    protected void onCreate(Bundle savedInstanceState) {

        userInputEditText = findViewById(;
        chatTextView = findViewById(;

        // Handle send button click
        findViewById( View.OnClickListener() {
            public void onClick(View v) {
                String userInput = userInputEditText.getText().toString().trim();
                if (!TextUtils.isEmpty(userInput)) {

    private void sendMessage(String message) {
        // Call OpenAI API to get response
        new Thread(new Runnable() {
            public void run() {
                try {
                    CompletionRequest completionRequest = new CompletionRequest.Builder()
                    CompletionResponse completionResponse = OpenAI.complete(completionRequest);

                    // Update UI with response
                    runOnUiThread(new Runnable() {
                        public void run() {
                } catch (Exception e) {

    private void displayMessage(String message) {
        // Display response in chat interface
        chatTextView.append("ChatGPT: " + message + "\n");

7. Handle Errors and Edge Cases

Implement robust error handling mechanisms to gracefully manage unexpected scenarios and edge cases, ensuring uninterrupted user interaction and a seamless customer support experience.

8. Test and Iterate

Evaluate the app's functioning in-depth during the "Test and Iterate" phase by modeling various support situations, getting user input, and continually improving the features and answers of the app based on insights gathered. By matching the software with user expectations and enhancing overall user pleasure, this iterative method promotes continuous enhancement.

9. Deploy Your App

Once your software is working properly, release it via alternate distribution methods like the Google Play Store. Verify that the application satisfies every requirement and deployment standard. After implementation, track user input and quickly resolve any problems to ensure the best possible user experience.
