 Built with the official [Model Context Protocol Go SDK](https://github.com/modelcontextprotocol/go-sdk), RagCode provides **9 powerful tools** for intelligent code search, function analysis, type definitions, and documentation retrieval across **multi-language projects**.
 
+## 🔒 Privacy-First: 100% Local AI
+
+**Your code never leaves your machine.** RagCode runs entirely on your local infrastructure:
+
+- ✅ **Local AI Models** - Uses Ollama for LLM and embeddings (runs on your hardware)
+- ✅ **Local Vector Database** - Qdrant runs in Docker on your machine
+- ✅ **Zero Cloud Dependencies** - No external API calls, no data transmission
+- ✅ **No API Costs** - Free forever, no usage limits or subscriptions
+- ✅ **Complete Privacy** - Your proprietary code stays private and secure
+- ✅ **Offline Capable** - Works without internet connection (after initial model download)
+- ✅ **Full Control** - You own the data, models, and infrastructure
+
+**Perfect for:** Enterprise codebases, proprietary projects, security-conscious teams, and developers who value privacy.

+### 🆚 RagCode vs Cloud-Based Solutions
+
+| Feature | RagCode (Local) | Cloud-Based AI Code Search |
+|---------|-----------------|---------------------------|
+| **Privacy** | ✅ 100% local, code never leaves machine | ❌ Code sent to cloud servers |
+| **Cost** | ✅ $0 - Free forever | ❌ $20-100+/month subscriptions |
+| **API Limits** | ✅ Unlimited usage | ❌ Rate limits, token caps |
+| **Offline** | ✅ Works without internet | ❌ Requires constant connection |
+| **Data Control** | ✅ You own everything | ❌ Vendor controls your data |
+| **Enterprise Ready** | ✅ No compliance issues | ⚠️ May violate security policies |
+| **Setup** | ⚠️ Requires local resources | ✅ Instant cloud access |
+| **Performance** | ✅ Fast (local hardware) | ⚠️ Depends on network latency |
+
+**Bottom Line:** RagCode gives you enterprise-grade AI code search with zero privacy concerns and zero ongoing costs.
