Introduction
Artificial Intelligence (AI) is changing the way websites interact with users. One of the simplest and most useful AI applications is a chatbot. Chatbots can answer questions, guide users, and improve user experience.
In this tutorial by AI Web Genix, you will learn how to create a simple AI chatbot using JavaScript. This project is perfect for beginners who want to understand how chatbots work using basic web technologies.
What Is an AI Chatbot?
An AI chatbot is a program that simulates human conversation. It receives user input, processes it, and returns a response. In this project, our chatbot will:
Accept user messages
Match keywords
Respond with predefined answers
This is a rule-based chatbot, which is the foundation of more advanced AI bots.
Technologies Used
We will use:
HTML – Structure of the chatbot
CSS – Styling the chatbot
JavaScript – Logic and AI behavior
No frameworks or libraries are required.
Step 1: Create the HTML Structure
<!DOCTYPE html>
<html>
<head>
<title>Simple AI Chatbot</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div class="chat-container">
<h2>AI Web Genix Chatbot</h2>
<div id="chat-box"></div>
<input type="text" id="userInput" placeholder="Type your message...">
<button onclick="sendMessage()">Send</button>
</div>
<script src="script.js"></script>
</body>
</html>
Step 2: Style the Chatbot with CSS
body {
font-family: Arial, sans-serif;
background: #f4f4f4;
}
.chat-container {
width: 300px;
margin: 50px auto;
background: white;
padding: 15px;
border-radius: 8px;
}
#chat-box {
height: 200px;
overflow-y: auto;
border: 1px solid #ddd;
padding: 10px;
margin-bottom: 10px;
}
.user {
color: blue;
}
.bot {
color: green;
}
Step 3: Add Chatbot Logic Using JavaScript
function sendMessage() {
let input = document.getElementById("userInput");
let message = input.value.toLowerCase();
let chatBox = document.getElementById("chat-box");
chatBox.innerHTML += `<p class="user">You: ${message}</p>`;
let response = "I don't understand. Please try again.";
if (message.includes("hello")) {
response = "Hello! How can I help you?";
} else if (message.includes("ai")) {
response = "AI stands for Artificial Intelligence.";
} else if (message.includes("web")) {
response = "Web development uses HTML, CSS, and JavaScript.";
}
chatBox.innerHTML += `<p class="bot">Bot: ${response}</p>`;
input.value = "";
}
How This Chatbot Works
1. User types a message
2. JavaScript checks for keywords
3. The chatbot selects a response
4. The response is displayed on the screen
This logic can be expanded with more rules or connected to real AI APIs later.
Why This Project Is Important
✔ Helps you understand JavaScript logic
✔ Builds confidence in AI concepts
✔ Can be improved into advanced chatbots
✔ Great project for beginners and portfolios
Next Improvements You Can Add
AI API integration (ChatGPT, Gemini, etc.)
Better UI design
Save chat history
Conclusion
Creating a simple AI chatbot using JavaScript is a great way to start learning Artificial Intelligence and web development. With just HTML, CSS, and JavaScript, you can build an interactive chatbot and improve it step by step.
