What problem does it solve?
Chroma removes the friction of building semantic search and retrieval workflows by giving you a simple way to store embeddings, attach metadata, and query related content without managing a heavy database setup.
Core Features & Use Cases
- Vector storage: Keep document embeddings in a local or server-based collection with persistent storage when needed.
- Metadata filtering: Narrow search results by source, category, score thresholds, or custom fields for more precise retrieval.
- RAG and document search: Power retrieval-augmented generation, knowledge base lookup, and similarity search across notes, PDFs, articles, or application data.
- Integration-ready: Works with common embedding functions and connects cleanly to LangChain and LlamaIndex workflows.
Quick Start
Use Chroma to create a collection, add documents with metadata, and run a semantic query against your local embedding database.
