10 Step Guide to Creating a ChatGPT Clone with ReactJS

Step 1: Plan Your Chatbot Features

Before writing any code, it’s important to first scope out the core functionality and features your clone will provide. You’ll want to define what problem your bot is solving for users and what user journeys it will support.

One of the main purposes of ChatGPT and similar assistants is providing helpful responses to a wide variety of questions. Therefore, basic question answering capabilities should form the foundation of your clone. This involves integrating with an AI model via API to understand natural language questions and respond appropriately. Another key focus area for ChatGPT is general conversation – allowing open discussions on any topic. While recreating ChatGPT’s full conversational range may not be feasible, supporting casual back-and-forth discussions would align well with users’ expectations of such a clone.

In addition to these core functions, consider potential customizations that could give your bot a unique identity. For example, users may enjoy customizing their bot avatar or profile name for a more personalized feel. Saving favorite conversations or topics could also help users engage further with particularly helpful discussions. You may want to eventually expand the bot to understand specific domains like news, weather or sports through targeted API integrations as well.

It’s also important to brainstorm how your clone might generate revenue over time to justify ongoing maintenance costs. Potential monetization strategies include premium features unlocked via subscriptions, targeted ads or sponsorships, or paid API access for enterprise users. Of course, the bot should remain free and useful for most basic needs.

Taking the time upfront to comprehensively map out desired functionality based on user needs and business goals will greatly aid technical development down the line.

Step 2: Set Up the React Environment

After defining high-level plans, it’s time to initialize your React project and lay the structural groundwork. To get started, you’ll need to install React and related dependencies using a package manager like npm.

First, make sure to have the latest versions of Node.js and npm installed globally on your development machine. Then open your command line interface and navigate to the project folder where you want your React app code to live.

Run npm init to generate a basic package.json file describing your project and dependencies. Next, initialize a new React app scaffold within the same folder by running the create-react-app CLI:

npm install create-react-app npx create-react-app chatbot-clone

This sets up the core React files and folder structure. Within your new /src folder, define initial top-level components like App.js along with folders for assets, components, utils and more. Import React and ReactDOM to render your initial  component tree.

You now have the basic plumbing in place to begin architecting and building out your React components!

Step 3: Design the UI/UX

Before writing any code, take time to design mockups of key pages and flows based on your feature planning. This involves visualizing how user needs will translate into actual interfaces.

Start by sketching out high-fidelity mockups with tools like Figma, noting important UI elements, flows, and states. Some suggestions based on ChatGPT include:

  • Chat Page: A message list wrapping input field for conversing with the bot
  • Profile Page: Customizing display name, avatar, and preferences
  • Settings: Options to filter topics/keywords or enable localization
  • Login/Registration: Onboarding new users to accounts

You’ll also want to plan your overall component structure and organization. A few base suggestions include:

  • ChatPage container for conversation inputs and responses
  • Reusable Message component for displaying sent/received content
  • UserProfile for account customizations
  • Shared layout components for structure consistency

Early design brings clarity on functionality before CSS styling. Take time to review mocks with others for feedback before translating into code.

Step 4: Build the Chat Interface

Once designing is complete, you’re ready to start building out actual React components. The chat interface will form the core experience, so begin here.

First create a ChatPage container component containing display logic and button callbacks. Inside, render placeholders for a MessageList and InputField child component:

function ChatPage() { return (
) }

Next, build out MessageList to map over mock messages and display a Message component for each one. Message can then conditionally render avatar, text, timestamp etc based on props.

For the InputField, maintain a controlled message state with onChange handler. Create a submit callback that logs the message for now. Consider adding scroll to bottom on new messages over time.

Some additional suggestions to refine behavior include:

  • Creating separate UserMessage and BotMessage wrappers
  • Adding loading indicators while awaiting bot responses
  • Styling components with CSS Modules for consistency

Have stubbed components in place allows iterating on further steps more fluidly.

Step 5: Integrate Chat Functionality

To bring the clone to life, you’ll need to integrate backend APIs for sending/receiving messages and powering the bot’s responses. There are a few popular approaches:

Self-Hosted Model

Train your own AI model using frameworks like TensorFlow, PyTorch, or HuggingFace Transformers. Deploy to a server using JSON RPC APIs. Requires considerable coding and hardware resources.

Public AI APIs

Services like Dialogflow, ChatGPT API or Anthropic provide AI via REST APIs. Easier setup for basic needs but less customization.

For our purposes, utilizing an existing AI service like ChatGPT API is a practical place to start.

Install a client like Axios for making HTTP requests. Create an api directory to house utility functions for endpoints:

// api/index.js export async function chatBotRequest(message) { const response = await axios.post('/chat', { message }); return response.data; }

Call this on input submit to sync UI/state:

submitMessage = async () => { // api call const response = await chatBotRequest(message); // update component state this.setState({ messages: [...messages, response] }); }

Now frontend <-> backend communication is established! Iteratively enhance and protect calls as needed.

Step 6: Deploy a Chatbot Backend

Your frontend is linked to an API, but where is the AI logic hosted? For basic prototyping, public APIs suffice. However, to gain full control ultimately requires self-hosting a model and deploying APIs yourself.

Some options for the backend include:


Anthropic’s ChatGPT is a commercial-friendly API built on the original model. Easy pay-as-you-go pricing but limits customization.


Google’s NLU platform provides tools to train variations of popular language models. Useful APIS and free tier but complex setup.

Self-Hosted Model

Train your own custom model using a framework like Transformers and deploy APIs with Flask/FastAPI. Requires ML expertise and compute resources.

For our purposes, we’ll use ChatGPT API for its plug-and-play simplicity on the backend. Sign up for an API key, configure it as an environment variable in your React app, then call endpoints from the frontend.

Once APIs are hooked up, all core functionality is connected! The backend provides brains while React powers the interactive face.

Step 7: Connect Frontend to Backend

Now that mock APIs are in place, it’s time to integrate real-time communication between your React frontend and external AI backend.

The key steps are:

  1. Make authorization header with API key on requests

  2. Call APIs on relevant events like form submit using Axios:

submitMessage = async () => { try { const response = await axios.post( '/chat', {message: this.state.message}, { headers: { 'Authorization': process.env.API_KEY }

Step 8: Add User Authentication

To enhance personalization and engage users further, adding basic authentication functionality would allow profile customizations and saving messages to an account.

Start by defining appropriate routes and JWT authentication middleware with packages like Express JWT. Protect routes like the user profile page:

submitMessage = async () => { try { const response = await axios.post( '/chat', {message: this.state.message}, { headers: { 'Authorization': process.env.API_KEY }

Build React registration and login pages connected to these routes. On successful login, save the JWT in localStorage:

submitMessage = async () => { try { const response = await axios.post( '/chat', {message: this.state.message}, { headers: { 'Authorization': process.env.API_KEY }

Global AuthContext allows consuming components to check auth state:

submitMessage = async () => { try { const response = await axios.post( '/chat', {message: this.state.message}, { headers: { 'Authorization': process.env.API_KEY }

With routes guarded, users can now save conversations, train models from their profiles, and more.

Step 9: Additional Features

Beyond the core stack, enhance the experience with extended functionality based on common chatbot features:

Saving Messages – Allow flagging and permalinking helpful responses for future reference. Back this by a Mongo database for persistence.

Skill Modules – Break specific domains like weather/news into isolated skills that can be swapped in/out dynamically.

Topic Filters – Construct regex filters to block unwanted content or personalize responses based on interests.

Admin Panel – Build a restricted dashboard to monitor usage, flag inappropriate responses, customize models/skills.

Multi-Lingual Support – Integrate translation APIs alongside core NLP for conversations across languages.

Payment Integration – Add premium features or digital goods purchasing via services like Stripe. Unlock more via subscriptions.

Iterative development allows evolving functionality based on analytics and feedback over time.

Step 10: Testing and Deployment
