# 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).
