# Overview
## What is Diaflow Vector Database?
The Diaflow Vector Database is an intelligent knowledge management system that enables you to upload, organize, and utilize your business documents, articles, and web content for AI-powered conversations and content generation. By converting your content into vector embeddings, the system allows for semantic search and contextual knowledge retrieval across your entire knowledge base.
