+# Smart Notes – Local Q&A (RAG MVP)
+
+This is a minimal, local-first MVP that allows users to ask natural-language questions over their markdown notes.
+
+## Features (Current MVP)
+
+- Loads markdown files from a local `notes/` directory
+- Supports natural-language questions (e.g., "what is AI", "where is AI used")
+- Returns sentence-level answers from notes
+- Shows the source note filename
+- Interactive CLI loop (type `exit` to quit)
+
+This is a starter implementation intended to be extended with embeddings and vector search in future iterations.
+
+---
+
+## How it works
+
+1. Notes are loaded from the local `notes/` directory.
+2. Question words (what, where, who, when, etc.) are filtered.
+3. Notes are split into sentences.
+4. Relevant sentences are returned based on keyword matching.
+
+---
+
+## How to run
+
+```bash
+python smart-notes/rag_mvp/qa_cli.py
+
+
+
+>> what is AI
+
+[1] From test.md:
+Artificial Intelligence (AI) is the simulation of human intelligence in machines.
+
+
+>>  what is machine learning
+how is machine learning used
+difference between AI and ML
