🚀 Quick Start Guide

1. Environment Setup

# Set environment variables
export OPENAI_API_KEY="your_openai_api_key"
export QDRANT_URL="your_qdrant_url"
export QDRANT_USE_HTTPS="true"  # or false for local

2. Install Dependencies

# Using uv (recommended)
uv pip sync requirements.txt

# Or using pip
pip install -r requirements.txt

3. Run Tests

python test_gradio_app.py

4. Launch Application

cd gradio-ai-tutor
./run.sh
# or python app.py

5. Access Interface

Local: http://localhost:7860
Network: http://0.0.0.0:7860

🧪 Testing & Validation

✅ Test Suite Results

All tests passing (4/4):

✅ Import Test: All dependencies load correctly
✅ Environment Test: Configuration variables validated
✅ App Initialization Test: Services start successfully
✅ User Validation Test: Phone/username validation works

🔍 Memory Isolation Testing

To verify user memory separation:

User A: alice + 1234567890 → Discuss prompt safety
User B: bob + 0987654321 → Discuss prompt structure
Return to User A: Should only remember safety conversation

📊 Technical Specifications
