How Vectorless DB Works (No Embeddings, No Vector DB!)

🚀 **Vectorless AI Explained | Build AI Without Vector Database (FastAPI + Ollama)** In this video, I’ll show you how to build a **Vectorless AI system** from scratch — without using embeddings or any vector database like ChromaDB or Pinecone. Instead of traditional RAG (Retrieval-Augmented Generation), we use a **simple and efficient approach**: ✔️ Direct data filtering ✔️ Context-based prompt building ✔️ LLM response generation using Ollama --- 🔥 **What you’ll learn in this video:** * What is Vectorless AI / Vectorless DB * Difference between Vector RAG vs Vectorless approach * How data is searched without embeddings * Step-by-step FastAPI backend implementation * How Ollama is used for response generation * Complete project flow explanation --- 🧠 **Tech Stack Used:** * FastAPI * Python * Ollama (LLM) * JSON-based data storage --- 📌 **Project Flow:** User Query → Data Filtering → Context Building → LLM → Response --- 💡 **Why Vectorless AI?** * Simple to build * No heavy infrastructure * Fast for small datasets * Beginner-friendly approach --- ⚠️ **Limitations:** * Not scalable for large datasets * No semantic search * Lower accuracy compared to vector-based systems --- 📂 **Source Code:** Github: https://github.com/Gowthambalan/vectorless_db --- 👍 If you found this helpful: * Like 👍 * Share 🔁 * Subscribe 🔔 for more AI & FastAPI projects --- 💬 Have questions or want advanced RAG (with vector DB)?
