Create a web application that serves as a chatbot interface. The layout should be simple, clear, and easy for users to interact with, ensuring that the flow of conversation is intuitive and engaging. The design should be mobile and desktop-friendly with a focus on providing a seamless user experience. Below are the components to include:

1. Header Section: Logo: Centered at the top of the page. The logo should be clickable and direct the user back to the homepage. Navigation Links: Links to "Home," "About," and optional "Help/FAQ" for users to quickly find additional information or support. User Authentication (Optional): "Sign In" and "Sign Up" buttons if personalized features or tracking are part of the app.
2. Main Chat Interface: Chat Window: A large, scrollable area for displaying conversation between the user and the bot. The chat window should take up most of the screen, with clear separation between bot and user messages (e.g., different colors or speech bubble styles). User Input Field: A clear input field at the bottom of the screen where users can type their messages. Use a placeholder text like "Type your message..." to guide users. Send Button: Located next to the input field. The button should be visually distinct, and when clicked, the user's message is submitted. Alternatively, the "Enter" key should also send the message. Voice Input (Optional): A microphone icon next to the input field, allowing users to speak their message instead of typing it. Bot Message Area: Responses from the chatbot should be displayed in clear speech bubbles, using a different color/style than the user's message. User Message Area: User messages should be shown in their own bubbles, easily distinguishable from the bot's messages. Typing Indicator: Display an animation (three dots or similar) to show that the bot is typing or processing a response.
3. Sidebar (Optional): FAQ Section: A section or expandable link to frequently asked questions, allowing users to find quick answers to common queries. Settings: A link to user settings where they can personalize their experience (e.g., language settings, theme preferences). Help or Contact Support: A link to a contact page or live support for users who need more assistance.
4. Footer Section: Privacy Policy: A link to the app's privacy policy, explaining how user data is collected and handled. Terms of Service: A link to the terms of service, outlining the rules for using the chatbot. Social Media Links (Optional): Links to the chatbot's social media accounts to foster user engagement and community building.
5. User Experience Features: Message History: As new messages are sent, the previous conversation should be scrollable and preserved so users can refer to past exchanges. Quick Reply Options: Offer quick reply buttons for common responses, such as "Yes," "No," "Help," or specific questions related to the user's query. Multimedia Support: The chatbot should be capable of sending images, videos, or links to provide more dynamic interactions. Error Handling: In case the bot doesn't understand the user's input, offer a gentle prompt like "Sorry, I didn’t quite get that. Could you try again?". Multilingual Support (Optional): Offer the ability to switch languages if the chatbot serves users in multiple regions. Responsive Design: The layout should adapt to different screen sizes (desktop, tablet, mobile), ensuring that the chat interface works well on all devices.
6. Bot Features: Greeting Flow: The bot should greet users when they first arrive or open the chat, with a welcoming message like "Hi! How can I help you today?". Contextual Awareness: The bot should remember the context of the conversation (e.g., past messages) and use that information to offer relevant responses. FAQ Handling: The bot should be able to automatically provide responses to common questions (pre-programmed FAQs). Personalization (Optional): If the user is logged in, the bot can provide personalized suggestions or content based on user preferences or past interactions.
7. Additional Considerations: Clear, Simple Design: Avoid clutter by using simple typography, clear visual hierarchy, and well-spaced components. Use colors and fonts that are easy on the eyes. Security: Ensure secure handling of sensitive information, especially if any user data is collected or stored.
