Decision.io is an intelligent web application that helps users make better decisions using AI and probability theory. It guides users through a structured decision-making process to determine whether they should explore new options or stick with familiar choices.

• AI-powered decision analysis
• Probability-based recommendations
• Personalized suggestions based on user inputs
• Interactive multi-step interface
• Statistical analysis of decision factors

• React (TypeScript)
• CSS for styling
• Axios for API calls

• Node.js with Express
• Google Generative AI (Gemini)
• CORS for cross-origin requests

1. Clone the repository git clone https://github.com/yourusername/decision-io.git cd decision-io

2. Install frontend dependencies cd frontend npm install

3. Install backend dependencies cd ../backendII npm install

4. Create a .env file in the backend directory with your Google API key: API_KEY=your_google_api_key_here

1. Start the backend server cd backendII npm start

2. Start the frontend development server cd ../frontend npm start

3. Access the application at http://localhost:3000

• Home Component: Main interface for user interaction
• CSS Styling: Custom styles for the application

• Server: Handles API requests and AI processing

1. User inputs a decision category

2. AI generates specific questions based on the category

3. User answers the questions

4. System calculates exploration probability using the formula: P(E) = T / (T + k) Where:

   • T = Number of times user chose familiar option
   • k = Exploration adjustment constant

5. AI generates personalized recommendations based on the analysis

• POST /api/category: Generates decision-specific questions
• POST /api/results: Processes user inputs and returns decision analysis

1. Fork the repository
2. Create a new branch (git checkout -b feature/YourFeatureName)
3. Commit your changes (git commit -m 'Add some feature')
4. Push to the branch (git push origin feature/YourFeatureName)
