+# Local RAG with Encoderfile + Llamafile
+
+A fully local RAG (Retrieval-Augmented Generation) system. Give it any text file, ask it questions. Everything stays local.
+
+- **Encoderfile** handles embedding locally. 
+- **Llamafile** runs the LLM locally. 
+- **NumPy** handles similarity search in memory.
+
+This is a good fit for offline environments, sensitive documents, or anywhere you need a simple, self-contained question-answering system without cloud dependencies.

+# CVE Semantic Search with Encoderfile + Qdrant
+
+A fully local, privacy-first vulnerability search system. Embed CVE descriptions with Encoderfile, store and search them with Qdrant — all self-hosted, no data leaves your network.
+
+This is a good fit for internal security teams that need natural language search for vulnerability reports, pen test findings, or bug bounty submissions where sending data to a cloud embedding API is not an option.
