🔧 How It Works

  1. User submits context (e.g., “I missed class today.”)
  2. React frontend sends the input to the backend via API Gateway.
  3. AWS Lambda function receives the input and forwards it to Gemini API.
  4. Gemini API returns a contextually appropriate excuse.
  5. Frontend displays the generated excuse to the user.
