### About
ChestAI uses advanced deep learning to detect pneumonia in chest X-rays.
### How to use
1. Upload a chest X-ray image (JPG/PNG)
2. Wait for the analysis
3. View the results and confidence score
### Note
This tool is for educational purposes only. Always consult healthcare professionals for medical advice.
