1. The frontend provides a chat interface where users can type messages
2. Messages are sent to the backend API endpoint
3. The backend uses the OpenAI API to generate responses
4. Responses are formatted and displayed in the chat interface

• TypeScript: For type safety and better code organization
• Tailwind CSS: For styling without custom CSS files
• Hono: Lightweight web framework for the backend
• OpenAI API: For generating AI responses

This app requires an OpenAI API key to be set as an environment variable in Val Town.

1. Fork this project in Val Town
2. Add your OpenAI API key as an environment variable named OPENAI_API_KEY
3. Run the project

You can customize the app by:

• Changing the OpenAI model in the backend (currently using gpt-4o-mini)
• Adjusting the max tokens parameter for longer or shorter responses
• Modifying the Tailwind classes to change the appearance
• Adding additional features like message history or user authentication
