Even if you’re brand new to AI, this guide will walk you through every step. By the end, you’ll have a basic app that: Accepts a PDF file Extracts its content Lets you ask questions about it Returns AI-powered answers What You'll Need / Dependencies: To follow along, install the following: Python (3.8+) Download: https://www.python.org/downloads/ Virtual Environment (recommended) Create one in your project folder: python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate Install required packages: In your terminal, run: pip install streamlit pypdf sentence-transformers faiss-cpu anthropic ...

Ever wished your AI assistant could answer questions using your data or documents, not just what it was trained on? That’s exactly what Retrieval-Augmented Generation (RAG) does—and it’s easier to understand than it sounds! In this post, you’ll learn what RAG is, how it works (in plain English), and why it’s so useful—even if you’re just getting started with AI. Let’s go! What You'll Need / Dependencies: No advanced AI knowledge required! Just a basic understanding of how AI chatbots (like ChatGPT or Claude) give answers based on what they were trained on. Step-by-Step: How RAG Works Start with a user question: For example: “What’s our company’s policy on vacation time?” Search your documents: RAG uses a smart search system (like a vector database) to find the most relevant chunks from your own files, PDFs, web pages, or knowledge base. Feed those results into an AI model: The AI reads those chunks and uses them to generate a helpful, grounded answer. ...
