Hello! I'm ChatGPT, your AI assistant. How can I help you today?

I'll help you create a React component for a chat interface. Here's a basic implementation:

import React, { useState } from 'react';

const ChatInterface = () => {
  const [messages, setMessages] = useState([]);
  const [input, setInput] = useState('');

  const sendMessage = () => {
    if (input.trim()) {
      setMessages([...messages, { text: input, sender: 'user' }]);
      setInput('');
    }
  };

  return (
    <div className="chat-container">
      <div className="messages">
        {messages.map((msg, idx) => (
          <div key={idx} className={`message ${msg.sender}`}>
            {msg.text}
          </div>
        ))}
      </div>
      <div className="input-area">
        <input
          value={input}
          onChange={(e) => setInput(e.target.value)}
          onKeyPress={(e) => e.key === 'Enter' && sendMessage()}
          placeholder="Type a message..."
        />
        <button onClick={sendMessage}>Send</button>
      </div>
    </div>
  );
};
