Overview

What if AI could understand documents like a human expert — without embeddings or vector databases? In this video, we break down the complete architecture of Vectorless RAG using PageIndex and compare it with Traditional RAG systems built with Pinecone, FAISS, ChromaDB, and other vector databases. We explore how Vectorless RAG uses hierarchical document reasoning and tree-based retrieval instead of traditional chunk-based semantic search, and when each approach makes sense for real-world production systems.
