+# Writing Studio - HuggingFace Spaces Edition
+
+This is the HuggingFace Spaces configuration for the AI Writing Studio.
+
+## About
+
+AI Writing Studio is a production-grade educational writing assistant that provides:
+- AI-powered text revision suggestions
+- Real rubric-based scoring (Clarity, Conciseness, Organization, Evidence, Grammar)
+- Visual diff highlighting
+- 5 specialized prompt packs (General, Literature, Tech Comm, Academic, Creative)
+
+## Features
+
+### Real Rubric Analysis
+Unlike simple prototypes, this version includes actual analysis algorithms:
+- **Clarity**: Analyzes sentence length, complexity, and structure
+- **Conciseness**: Detects wordy phrases and redundancy
+- **Organization**: Checks paragraph structure and transitions
+- **Evidence**: Looks for supporting examples and data
+- **Grammar**: Basic error detection
+
+### Multiple Prompt Packs
+Choose from specialized templates:
+- **General**: Everyday writing
+- **Literature**: Literary analysis
+- **Tech Comm**: Technical documentation
+- **Academic**: Research papers
+- **Creative**: Stories and creative writing
+
+### Production Quality
+- Comprehensive error handling
+- Input validation and sanitization
+- Structured logging
+- Caching for faster responses
+- Type-safe configuration
+
+## Usage
+
+1. **Paste your text** in the input box
+2. **Select a model** (distilgpt2 is fastest, gpt2 has better quality)
+3. **Choose a prompt pack** matching your writing context
+4. **Click "Analyze & Compare"** to get feedback
+
+### Tips
+
+- First analysis may take 30-60 seconds (model loading)
+- Subsequent analyses are much faster (caching)
+- Start with shorter texts for quicker results
+- Try different prompt packs for varied perspectives
+- Use the rubric feedback to learn and improve
+
+## Models
+
+**Default: distilgpt2**
+- Fast and efficient
+- Works well on free tier
+- Good for most use cases
+
+**Alternative: gpt2**
+- Better quality revisions
+- Slower processing
+- May need upgraded hardware on HF Spaces
+
+**Advanced: gpt2-medium, gpt2-large**
+- Best quality
+- Significantly slower
+- Requires upgraded HF Spaces hardware
+
+## Performance
+
+### Hardware Recommendations
+
+**Free Tier (CPU Basic)**
+- Works with distilgpt2
+- First load: ~30-60s
+- Subsequent: ~5-10s per analysis
+
+**CPU Upgrade**
+- Handles gpt2 well
+- First load: ~45s
+- Subsequent: ~8-15s
+
+**T4 GPU**
+- Best performance
+- First load: ~20s
+- Subsequent: ~2-5s
+
+### Optimization
+
+The app includes several optimizations:
+- Model caching (loaded once, reused)
+- Result caching (same input = instant response)
+- Lazy loading of services
+- Efficient text processing
+
+## Configuration
+
+The app works out-of-the-box with sensible defaults. To customize:
+
+### Via HuggingFace Spaces Settings
+
+Go to Settings → Variables and add:
+
+```
+DEFAULT_MODEL=gpt2
+LOG_LEVEL=DEBUG
+MAX_TEXT_LENGTH=5000
+ENABLE_CACHE=true
+```
+
+### Via .space_config.yml
+
+Edit `.space_config.yml`:
+
+```yaml
+env:
+  DEFAULT_MODEL: gpt2
+  LOG_LEVEL: INFO
+```
+
+## Troubleshooting
+
+### "Out of Memory" Error
+- Use a smaller model (distilgpt2)
+- Upgrade to better hardware
+- Reduce text length
+
+### Slow First Load
+- Normal behavior (model downloading)
+- Subsequent loads are much faster
+- Consider upgrading hardware tier
+
+### "Model Loading Failed"
+- Check model name spelling
+- Ensure internet connectivity
+- Try default model (distilgpt2)
+
+### Unexpected Results
+- Try different prompt pack
+- Check input text quality
+- Remember: AI suggestions aren't perfect
+
+## Privacy
+
+- Text processed in-memory only
+- Results cached temporarily for speed
+- No long-term storage on HF Spaces
+- No user tracking

+
+                - Start with shorter texts for faster results
+                - Try different prompt packs for specialized feedback
+                - Review the rubric feedback to understand strengths and areas for improvement
+                - The first analysis may take 30-60s as the model loads (subsequent analyses are faster)

+# HuggingFace Spaces Deployment Guide
+
+## Overview
+
+This guide explains how to deploy Writing Studio on HuggingFace Spaces for free, public access to your AI writing assistant.
+
+## Prerequisites
+
+- HuggingFace account ([sign up free](https://huggingface.co/join))
+- Basic familiarity with Git (optional for direct upload)
+
+## Quick Deploy
+
+### Method 1: Direct Upload (Easiest)
+
+1. **Create a Space**
+   - Go to [huggingface.co/new-space](https://huggingface.co/new-space)
+   - Name your Space (e.g., "writing-studio")
+   - Choose **Gradio** as SDK
+   - Select visibility (Public or Private)
+   - Click "Create Space"
+
+2. **Upload Files**
+   - Click "Files" tab
+   - Upload these essential files:
+     - `app.py`
+     - `requirements.txt`
+     - `src/` folder (entire directory)
+     - `.space_config.yml` (optional)
+     - `README_HF_SPACES.md` (rename to README.md)
+
+3. **Wait for Build**
+   - HuggingFace automatically detects `app.py` and `requirements.txt`
+   - First build takes 3-5 minutes (installing dependencies)
+   - Your Space will be live at: `https://huggingface.co/spaces/USERNAME/SPACE_NAME`
+
+### Method 2: Git Clone (Recommended for Updates)
+
+1. **Create a Space** (as above)
+
+2. **Clone Locally**
+   ```bash
+   git clone https://huggingface.co/spaces/USERNAME/SPACE_NAME
+   cd SPACE_NAME
+   ```
+
+3. **Copy Files**
+   ```bash
+   # From your WritingStudio directory
+   cp -r src/ app.py requirements.txt .space_config.yml /path/to/SPACE_NAME/
+   cp README_HF_SPACES.md /path/to/SPACE_NAME/README.md
+   ```
+
+4. **Push to Space**
+   ```bash
+   cd /path/to/SPACE_NAME
+   git add .
+   git commit -m "Initial deployment"
+   git push
+   ```
+
+5. **Monitor Build**
+   - Go to your Space URL
+   - Check "Logs" tab for build progress
+   - App will be live when build completes
+
+### Method 3: Duplicate an Existing Space
+
+If someone has already deployed Writing Studio:
+
+1. Go to their Space
+2. Click "⋯" menu → "Duplicate this Space"
+3. Choose your username and Space name
+4. Click "Duplicate Space"
+5. Done! Your own copy is live
+
+## Configuration
+
+### Default Settings
+
+Works out-of-the-box with:
+- Model: `distilgpt2` (fast, lightweight)
+- Log Level: `INFO`
+- Metrics: Disabled (not needed on HF Spaces)
+- Caching: Enabled
+- All rubric features: Enabled
+
+### Custom Configuration
+
+#### Option A: Environment Variables
+
+In your Space:
+1. Go to Settings
+2. Scroll to "Repository secrets"
+3. Add variables:
+
+```
+DEFAULT_MODEL=gpt2
+LOG_LEVEL=DEBUG
+MAX_TEXT_LENGTH=5000
+```
+
+#### Option B: Edit .space_config.yml
+
+```yaml
+env:
+  DEFAULT_MODEL: gpt2
+  LOG_LEVEL: INFO
+  ENABLE_CACHE: "true"
+  MAX_TEXT_LENGTH: "5000"
+```
+
+Commit and push changes.
+
+## Hardware Selection
+
+### Free Tier (CPU Basic)
+
+**Best for:**
+- Testing and demos
+- Small models (distilgpt2)
+- Light usage
+
+**Performance:**
+- First load: ~30-60s
+- Subsequent: ~5-10s per analysis
+- Memory: 16GB RAM
+- Storage: Unlimited
+
+**Limitations:**
+- Slower processing
+- May timeout on large models
+
+### CPU Upgrade (Paid)
+
+**Best for:**
+- Production use
+- Medium models (gpt2)
+- Regular users
+
+**Performance:**
+- First load: ~20-45s
+- Subsequent: ~3-8s
+- More CPU cores
+- Better throughput
+
+**Cost:** ~$0.10/hour
+
+### T4 Small GPU (Paid)
+
+**Best for:**
+- Best performance
+- Large models (gpt2-medium, gpt2-large)
+- High traffic
+
+**Performance:**
+- First load: ~15-30s
+- Subsequent: ~1-3s
+- GPU acceleration
+- Fastest generation
+
+**Cost:** ~$0.60/hour
+
+### Recommendation
+
+Start with **Free Tier + distilgpt2**:
+- Works well for most use cases
+- Zero cost
+- Upgrade only if needed
+
+## Model Selection
+
+### distilgpt2 (Default)
+- **Size:** 82M parameters
+- **Speed:** Fast
+- **Quality:** Good
+- **Free Tier:** ✅ Works great
+- **Recommended for:** Most users
+
+### gpt2
+- **Size:** 124M parameters
+- **Speed:** Medium
+- **Quality:** Better
+- **Free Tier:** ✅ Works (slower)
+- **Recommended for:** CPU Upgrade tier
+
+### gpt2-medium
+- **Size:** 355M parameters
+- **Speed:** Slower
+- **Quality:** Great
+- **Free Tier:** ⚠️ May timeout
+- **Recommended for:** T4 GPU tier
+
+### gpt2-large
+- **Size:** 774M parameters
+- **Speed:** Slowest
+- **Quality:** Best
+- **Free Tier:** ❌ Not recommended
+- **Recommended for:** T4 GPU tier
+
+## Optimization Tips
+
+### 1. Enable Caching (Default)
+Results are cached automatically:
+- Same input = instant result
+- Reduces compute time
+- Saves hardware costs
+
+### 2. Use Smaller Models
+For free tier:
+```yaml
+env:
+  DEFAULT_MODEL: distilgpt2
+```
+
+### 3. Limit Text Length
+Prevent timeouts:
+```yaml
+env:
+  MAX_TEXT_LENGTH: "3000"  # Shorter = faster
+```
+
+### 4. Adjust Generation Length
+Faster processing:
+```yaml
+env:
+  DEFAULT_MAX_LENGTH: "200"  # Instead of 300
+```
+
+## Monitoring
+
+### Check Logs
+
+1. Go to your Space
+2. Click "Logs" tab
+3. View real-time logs
+
+Look for:
+- `INFO` - Normal operations
+- `WARNING` - Potential issues
+- `ERROR` - Problems to fix
+
+### Usage Stats
+
+HuggingFace provides:
+- View count
+- Unique visitors
+- Uptime status
+
+Available in Space settings.
+
+## Troubleshooting
+
+### Build Fails
+
+**Problem:** Space doesn't build
+
+**Solutions:**
+1. Check `requirements.txt` syntax
+2. Ensure `app.py` exists
+3. Check Logs tab for errors
+4. Verify file structure:
+   ```
+   SPACE_NAME/
+   ├── app.py
+   ├── requirements.txt
+   ├── src/
+   │   └── writing_studio/
+   │       ├── core/
+   │       ├── services/
+   │       └── utils/
+   ```

+
+**Problem:** "CUDA out of memory" or crashes
+
+**Solutions:**
+1. Use smaller model:
+   ```python
+   DEFAULT_MODEL=distilgpt2
+   ```
+2. Reduce cache size:
+   ```python
+   CACHE_MAX_SIZE=50
+   ```
+3. Upgrade to larger hardware tier
+
+### Slow Performance
+
+**Problem:** Analysis takes too long
+
+**Solutions:**
+1. First load is always slow (model download)
+2. Use distilgpt2 for faster results
+3. Upgrade hardware tier
+4. Reduce text length
+5. Check cache is enabled
+
+### Model Not Found
+
+**Problem:** "Model ... not found"
+
+**Solutions:**
+1. Check model name spelling
+2. Verify model exists on HuggingFace Hub
+3. Try default: `distilgpt2`
+4. Check internet connectivity
+
+### Import Errors
+
+**Problem:** "ModuleNotFoundError"
+
+**Solutions:**
+1. Ensure all files uploaded
+2. Check `src/` directory structure
+3. Verify `requirements.txt` has all dependencies
+4. Rebuild Space (Settings → Factory reboot)
+
+## Best Practices
+
+### 1. Use README_HF_SPACES.md
+
+Rename to `README.md` in your Space:
+```bash
+cp README_HF_SPACES.md README.md
+```
+
+This provides users with:
+- Usage instructions
+- Model selection guide
+- Troubleshooting help
+
+### 2. Add Examples
+
+In your Space README, add example texts:
+
+````markdown
+## Example Usage
+
+Try analyzing this text:
+
+```
+The quick brown fox jumps over the lazy dog. This sentence
+demonstrates pangram characteristics while maintaining
+grammatical coherence.
+```
+````
+
+### 3. Set Visibility
+
+**Public Spaces:**
+- Visible to everyone
+- Searchable
+- Can be featured
+- Free community tier
+
+**Private Spaces:**
+- Only visible to you
+- Not searchable
+- Requires paid tier
+
+### 4. Monitor Costs
+
+If using paid tiers:
+1. Go to Settings → Billing
+2. Set spending limits
+3. Monitor usage
+4. Downgrade when not in use
+
+### 5. Update Regularly
+
+Keep your Space updated:
+```bash
+git pull origin main  # From main repo
+git push              # To your Space
+```
+
+## Advanced Configuration
+
+### Custom Domain
+
+Point your domain to your Space:
+1. Go to Settings
+2. Under "Custom domain"
+3. Enter your domain
+4. Follow DNS instructions
+
+### Gradio Auth
+
+Add simple authentication:
+
+Edit `app.py`:
+```python
+demo.launch(
+    auth=("username", "password"),
+    server_name="0.0.0.0",
+)
+```
+
+### Analytics
+
+Track usage with Gradio analytics:
+
+```python
+demo.launch(
+    server_name="0.0.0.0",
+    analytics_enabled=True,  # HF Spaces analytics
+)
+```
+
+### Sleep Mode
+
+Free Spaces sleep after 48h inactivity:
+- First request wakes it up (~30s)
+- Paid tiers can disable sleep
+
