# To get your own key:
# 1. Go to: https://aistudio.google.com/app/apikey
# 2. Create new project or select existing
# 3. Generate API key
# 4. Replace in /app/backend/server.py line 18

2. MongoDB Database

# Current Configuration
MONGO_URL=mongodb://localhost:27017
DB_NAME=sada_ai

# To use different database:
# 1. Update /app/backend/.env file
# 2. Change MONGO_URL and DB_NAME variables

🔄 API Replacement Guide

Replacing Gemini API with Other LLM Providers:

Option 1: OpenAI Integration

# Change model configuration:
chat = LlmChat(
    api_key="your-openai-key",
    session_id=session_id,
    system_message="Your system message"
).with_model("openai", "gpt-4o")  # or other OpenAI models

Option 2: Anthropic Claude Integration

# Change model configuration:
chat = LlmChat(
    api_key="your-anthropic-key",
    session_id=session_id,
    system_message="Your system message"
).with_model("anthropic", "claude-sonnet-4-20250514")

Available Models:

# OpenAI Models:
'gpt-4.1', 'gpt-4.1-mini', 'o4-mini', 'o3-mini', 'o3', 'gpt-4o', 'o1-pro'

# Anthropic Models:
'claude-sonnet-4-20250514', 'claude-opus-4-20250514', 'claude-3-5-sonnet-20241022'

# Gemini Models:
'gemini-2.5-flash-preview-04-17', 'gemini-2.0-flash', 'gemini-1.5-pro'

API Key Replacement Steps:

1. Update API Key: Replace in /app/backend/server.py line 18
2. Change Model: Update .with_model() calls (lines ~85, ~165)
3. Restart Backend: sudo supervisorctl restart backend

🗄 Database Configuration

MongoDB Setup:

# Default connection (already configured)
MONGO_URL=mongodb://localhost:27017
DB_NAME=sada_ai

# Collections created automatically:
- chat_sessions
- document_analyses  
- chat_messages
- status_checks

Using Different Database:

# 1. Update /app/backend/.env
MONGO_URL=mongodb://your-mongo-host:27017
DB_NAME=your_database_name

# 2. Or use MongoDB Atlas (cloud):
MONGO_URL=mongodb+srv://username:[email protected]/
DB_NAME=your_database_name

# 3. Restart backend
sudo supervisorctl restart backend

🚨 Important Notes

API Key Security:

• Never commit API keys to version control
• Use environment variables in production
• Rotate keys regularly

Performance:

• 3D animations are GPU-accelerated
• File uploads use base64 encoding
• MongoDB indexes recommended for production

Browser Compatibility:

• Chrome 90+ (recommended)
• Firefox 88+
• Safari 14+
• Mobile browsers supported

---

🆘 Troubleshooting

Common Issues:

1. Backend not starting:

   tail -n 100 /var/log/supervisor/backend.*.log

2. Frontend build errors:

   cd /app/frontend
   yarn install

3. API connection issues:

   • Check REACT_APP_BACKEND_URL in frontend/.env
   • Ensure backend is running on correct port

4. 3D animations not working:

   • Check browser WebGL support
   • Update graphics drivers

---

📞 Support

For issues with:

• LLM Integration: Check API key validity
• Database: Verify MongoDB connection
