What problem does it solve?
Chroma eliminates slow, manual document retrieval by turning your text into embeddings and enabling fast similarity search with metadata filters for precise RAG results.
Core Features & Use Cases
- Semantic vector search with metadata filtering: Retrieve the most relevant chunks while narrowing results using tags, categories, timestamps, or numeric constraints.
- Simple self-hosted embedding storage: Store embeddings and documents locally for notebooks, prototypes, and production systems.
- Multi-framework integration: Plug into common LLM stacks like LangChain and LlamaIndex to power retrieval-augmented generation.
Use it when you are building a RAG pipeline that must search across your own knowledge base and only return sources that match constraints like document type (e.g., "tutorial"), difficulty level, or freshness date.
Quick Start
Create a Chroma collection, add your documents with metadata, and run a similarity query to get the top matching passages for your question.
