+# Browser Whisper Self-Hosted Setup
+
+## Overview
+
+As of v18, Browser Whisper is **fully self-hosted** with **zero CDN dependencies**. All models and libraries are bundled with the application.
+
+## What Changed
+
+**Before (v17 and earlier):**
+- Loaded transformers.js from `cdn.jsdelivr.net`
+- Downloaded models from `cdn-lfs.huggingface.co`
+- Failed in corporate/clinical networks with firewall restrictions
+
+**Now (v18+):**
+- Transformers.js library bundled at `/models/transformers.min.js`
+- Whisper model bundled at `/models/Xenova/whisper-tiny.en/`
+- Everything served from your own server
+- **Works in any network environment**
+
+## Files Included
+
+```
+public/models/
+├── transformers.min.js                    (~876KB) - Transformers.js library
+└── Xenova/
+    └── whisper-tiny.en/                   (~42MB total)
+        ├── config.json
+        ├── tokenizer.json
+        ├── preprocessor_config.json
+        ├── generation_config.json
+        └── onnx/
+            ├── encoder_model_quantized.onnx
+            └── decoder_model_merged_quantized.onnx
+```
+
+## How It Works
+
+1. **Worker loads transformers.js locally:**
+   ```javascript
+   importScripts('/models/transformers.min.js');
+   ```
+
+2. **Transformers.js configured for local models:**
+   ```javascript
+   T.env.localModelPath = '/models/';
+   T.env.allowRemoteModels = false;
+   ```
+
+3. **Models load from your server:**
+   - Browser requests: `GET /models/Xenova/whisper-tiny.en/config.json`
+   - Served by Express static middleware
+   - No external network calls
+
+## Docker Build
+
+Models are downloaded **during Docker build** (not runtime):
+
+```dockerfile
+RUN curl -sL -o onnx/encoder_model_quantized.onnx \
+    https://huggingface.co/Xenova/whisper-tiny.en/resolve/main/onnx/encoder_model_quantized.onnx
+```
+
+This means:
+- Docker image is ~200MB larger (one-time cost)
+- Runtime has zero dependencies
+- Works in air-gapped environments (after image is pulled)
+
+## Development Setup
+
+If you're running locally (not Docker), download models:
+
+```bash
+cd public/models
+mkdir -p Xenova/whisper-tiny.en/onnx
+
+# Download transformers.js
+curl -L -o transformers.min.js \
+  https://cdn.jsdelivr.net/npm/@xenova/transformers@2.17.2/dist/transformers.min.js
+
+# Download model files
+cd Xenova/whisper-tiny.en
+curl -L -o config.json \
+  https://huggingface.co/Xenova/whisper-tiny.en/resolve/main/config.json
+curl -L -o tokenizer.json \
+  https://huggingface.co/Xenova/whisper-tiny.en/resolve/main/tokenizer.json
+curl -L -o preprocessor_config.json \
+  https://huggingface.co/Xenova/whisper-tiny.en/resolve/main/preprocessor_config.json
+curl -L -o generation_config.json \
+  https://huggingface.co/Xenova/whisper-tiny.en/resolve/main/generation_config.json
+curl -L -o onnx/encoder_model_quantized.onnx \
+  https://huggingface.co/Xenova/whisper-tiny.en/resolve/main/onnx/encoder_model_quantized.onnx
+curl -L -o onnx/decoder_model_merged_quantized.onnx \
+  https://huggingface.co/Xenova/whisper-tiny.en/resolve/main/onnx/decoder_model_merged_quantized.onnx
+```
+
+Or use the helper script:
+
+```bash
+./scripts/download-whisper-models.sh
+```
+
+## Adding More Models
+
+To add base or small models:
+
+1. **Create directory:**
+   ```bash
+   mkdir -p public/models/Xenova/whisper-base.en/onnx
+   ```
+
+2. **Download from HuggingFace:**
+   - https://huggingface.co/Xenova/whisper-base.en
+   - https://huggingface.co/Xenova/whisper-small.en
+
+3. **Update UI in `settings.html`:**
+   ```html
+   <option value="Xenova/whisper-base.en">Base (~74MB, better quality)</option>
+   ```
+
+4. **Update Dockerfile** to download during build
+
+## Benefits
+
+✅ **Works everywhere** - No firewall/CDN issues
+✅ **Privacy-first** - Audio never leaves browser
+✅ **Offline capable** - After initial page load
+✅ **No API costs** - Zero transcription expenses
+✅ **Predictable** - Same model, same results
+✅ **Fast** - Local processing, no network latency
+
+## Limitations
+
+- Docker image is larger (~200MB vs ~150MB)
+- Only tiny model included by default (base/small optional)
+- Slower than cloud APIs for long recordings
+- Requires modern browser with WebAssembly support
+
+## Testing
+
+```bash
+# 1. Start server
+docker-compose up -d
+
+# 2. Open browser DevTools → Network tab
+# 3. Go to Settings → Browser Transcription
+# 4. Click "Pre-download model"
+# 5. Watch for requests to /models/* (should all be 200 OK from your server)
+# 6. NO requests to cdn.jsdelivr.net or huggingface.co
+```
+
+## Troubleshooting
+
+**Issue: "Failed to load transformers library"**
+- Check: `GET /models/transformers.min.js` returns 200 OK
+- Verify file exists: `ls public/models/transformers.min.js`
+
+**Issue: "Model load failed"**
+- Check: `GET /models/Xenova/whisper-tiny.en/config.json` returns 200 OK
+- Verify files exist: `ls public/models/Xenova/whisper-tiny.en/`
+
+**Issue: Still seeing CDN requests**
+- Clear browser cache (Ctrl+Shift+R)
+- Check you're running v18+ (`/api/health` should show version)
+
+## Migration from v17
+
+If upgrading from v17:
+
+1. Pull new Docker image: `docker-compose pull`
+2. Restart: `docker-compose up -d`
+3. Clear browser cache
+4. Test: Settings → Browser Transcription → Pre-download
+
+No configuration changes needed - it just works!
