🧠 Knowledge-Retrieval-Engine-Using-LangChain-and-Retrieval-Augmented-Generation - Easy Context-Aware Answers
This application helps you find clear answers from large sets of information. It uses smart technology to understand your questions and looks through documents to give you useful responses. You do not need to know programming to use it.
Behind the scenes, it uses methods called LangChain and Retrieval-Augmented Generation (RAG). It organizes information using a FAISS vector database and a language model (LLM) to give answers that fit your questions well.
You can use this tool to get answers from books, notes, or any documents you add. It works on Windows computers.
Before you start, make sure your computer meets these needs:
- Windows 10 or later (64-bit recommended)
- At least 4 GB of free disk space
- 8 GB or more of RAM (more helps with larger files)
- Internet connection (for downloading and language model updates)
- A modern web browser (for viewing the application interface)
- Fast search through large documents
- Context-aware answers, not just simple keyword matches
- Stores and organizes data for easy retrieval
- Simple interface designed for everyday users
- Works offline after setup, no continuous internet needed for questions
- Supports adding your own files like PDFs, text documents, or notes

The engine uses a combination of smart tools to give accurate answers:
- LangChain: Helps connect different parts, like the question and your documents.
- Retrieval-Augmented Generation (RAG): It searches documents and then writes answers based on what it finds.
- FAISS Vector Database: This is a way to store documents so the app can find answers fast.

This tech lets you type naturally and get answers that consider context, not just keywords.
