Vector Database explained in Tamil | How Vector Databases Power AI & RAG Systems | Karthik's Show

What if AI could remember meaning — not just words? In this video, we dive deep into the hidden world of Vector Databases — the memory system that powers modern AI like ChatGPT, RAG, and intelligent agents. All explained in Tamil. You’ll learn: 1. What are vectors and embeddings — explained with simple analogies 2. How embedding models convert text into numbers that represent meaning 3. How vector databases store and search information efficiently 4. Why they’re critical for Retrieval-Augmented Generation (RAG) 5. Real-world examples and use cases you can relate to By the end, you’ll not just understand vector databases — you’ll see how they shape the way AI thinks, remembers, and reasons.
