+# PM-RAG-ChatBot (CedroPM)
+
+A specialized RAG (Retrieval Augmented Generation) chatbot designed for Project Managers and Software Architects. It processes Software Requirements Documents (SRDs) and provides expert-level analysis by combining project-specific data with a pre-seeded "Gold Standard" knowledge base of industry best practices.
+
+## 🚀 Key Features
+
+* **📄 Intelligent SRD Analysis**: Upload PDF requirements and get answers grounded strictly in your document.
+* **🧠 Global Expert Knowledge**: Pre-seeded with 30+ industry standards (ISO, OWASP, NIST, Agile) to provide "Senior Architect" advice even when your PDF is silent.
+* **🎨 Diagram Vision**: Understands and explains architecture diagrams using Claude Vision or Qwen2-VL.
+* **🔍 Hybrid Search**: Uses a dual-scope retrieval engine to search your **Project PDF** and **Global Best Practices** simultaneously.
+* **💬 Interactive Chat**: Built with Chainlit for a clean, chat-like interface with history retention.
+* **🔐 Secure & Private**: Multi-user isolation ensures one project's data never leaks to another.
+
+## 🏗️ System Architecture
+
+1.  **Ingestion Layer**:
+    * **PDFs**: Processed with `pdfplumber` and `SmartSRDSplitter` (Section-aware chunking).
+    * **Tables**: Extracted via `camelot` and converted to Markdown.
+    * **Diagrams**: Processed via OCR (`Tesseract`) or Vision LLM (`Claude 3.5 Sonnet`).
+2.  **Knowledge Store**:
+    * **ChromaDB**: vector storage for semantic search.
+    * **Dual-Scope**: Queries filter by `(User + Project)` OR `(Global_Expert_Knowledge)`.
+3.  **Reasoning Engine**:
+    * **Claude 3.5 Sonnet**: Generates detailed, structured responses.
+    * **Seed Data**: A Python script injects "Golden Rules" for Security, DevOps, and PM methodologies.
+
+## 📋 Prerequisites
+
+* **Python 3.10+**
+* **System Tools**:
+    * `Poppler` (for PDF rendering)
+    * `Tesseract OCR` (for image text extraction)
+* **API Key**: Anthropic API Key (for Claude).
