# 🚀 Ready to Test - Quick Start

## ✅ Installation Complete

All dependencies have been successfully installed:
- fastapi (FastAPI web framework)
- uvicorn (ASGI server)
- lxml (XML processing)
- transformers (AI/ML models)
- torch (PyTorch ML framework)
- pillow/PIL (image processing)
- python-docx (Word document handling)
- pywin32 (Windows COM automation)
- python-dotenv (environment configuration)

## 📋 What's Installed

**Core AI System:**
- `local_vision.py` - FREE local AI model integration (BLIP/GIT)

**Server:**
- `server2.py` - Main FastAPI backend with alt text remediation

**Config:**
- `requirements.txt` - Updated with compatible versions
- `.env.example` - Configuration template (optional)
- `.gitignore` - Protects .env files

**Testing:**
- `test_ai_setup.py` - Diagnostic test script

**Docs:**
- `QUICKSTART.md` - Quick start guide
- `README.md` - Project overview

## 🚀 To Start the Server

```bash
cd python-server
python server2.py
```

You should see:
```
✅ Local AI vision model loaded (BLIP - 100% FREE, No Costs)
🚀 Server running on http://localhost:5000
```

**First run will download BLIP model (~1-2GB) - takes 5-15 minutes**

## 🧪 To Test AI Setup

```bash
cd python-server
python test_ai_setup.py
```

This will verify:
- ✅ Transformers library
- ✅ Local BLIP model
- ✅ Image processing
- ✅ AI alt text generation

## 💰 Cost Verification

| Component | Cost |
|-----------|------|
| Local BLIP AI | $0 |
| Unlimited alt text generation | $0/month |
| API keys required | 0 |
| Surprise billing | IMPOSSIBLE |

## ⚠️ Important Notes

1. **No .env file needed** - System works with defaults
2. **First run is slow** - BLIP model downloads (~1-2GB, 5-15 min)
3. **Subsequent runs are fast** - Model is cached locally
4. **100% private** - Images never leave your computer
5. **100% free** - No API calls, no costs

## ✨ What's Removed

- ❌ OpenAI integration (not recommended for students)
- ❌ API key configuration (no longer needed)
- ❌ Paid billing risk (completely eliminated)
- ❌ Unnecessary documentation files (cleaned up)

## 🎯 Next Steps

1. **Start the server:**
   ```bash
   python server2.py
   ```

2. **Upload a PowerPoint file** through the Angular frontend

3. **Watch the console** for AI progress:
   ```
   🤖 Using FREE local AI (BLIP) for slide 1
   ✅ AI generated alt text for Picture 1: '...'
   ```

4. **Download the remediated PowerPoint**

## 🐛 Troubleshooting

### "Module not found" errors
```bash
pip install -r requirements.txt
```

### First run taking forever
Normal! BLIP model is ~1-2GB. Wait 5-15 minutes. After download completes, subsequent runs are instant.

### Out of memory
Close other programs or use:
```bash
# In .env:
LOCAL_VISION_MODEL=blip-base
```

### Can't connect to server
Check that:
1. Server is running: `python server2.py`
2. Port 5000 is available
3. Firewall allows localhost:5000
