Open-source vector database for AI applications with fast similarity search, full-text search, and object-storage-optimized indexes
Chroma is an open-source vector database purpose-built for AI applications. It handles the storage and retrieval of embeddings — the numerical representations that AI models use to understand text, images, and other data. When you're building RAG (Retrieval Augmented Generation) systems, semantic search, or AI agents that need memory, Chroma provides the infrastructure layer that makes retrieval fast and accurate.
The database supports three search modes: vector similarity search (finding semantically similar content), full-text search (traditional keyword matching), and regex search (pattern-based queries). This combination means you can build hybrid retrieval systems that use both semantic understanding and keyword precision, which typically outperforms either approach alone.
