🧠 How AI Remembers: Master Vector Stores with Pinecone, FAISS & ChromaDB

Imagine if your AI assistant could remember everything you’ve told it, even across different sessions. Or if it could instantly fetch the most relevant files, articles, or answers from a huge pile of data. That’s the job of a vector store—a special kind of memory bank built for embeddings, not plain text. In this guide, we’ll explore what vector stores are, why they matter, and how tools like Pinecone, FAISS, and ChromaDB help you build powerful, memory-enabled AI applications.
