ChromaDB Has a Free Embedding Database That Makes AI Apps Simple to Build

Chroma is the open-source embedding database. It makes it easy to build AI applications with embeddings — store, search, and retrieve in 4 lines of code.

What You Get for Free

• Simple API — 4 lines to store and search
• Built-in embeddings — auto-embed with sentence-transformers
• Metadata filtering — filter results by metadata
• Persistent storage — SQLite + Parquet backend
• Client/Server mode — embed or run as service
• LangChain/LlamaIndex — first-class integrations

Quick Start

pip install chromadb

Store and Search

import chromadb

client = chromadb.Client()
collection = client.create_collection('docs')

collection.add(
    documents=['AI is transforming healthcare', 'Python is great for ML'],
    ids=['doc1', 'doc2']
)

results = collection.query(query_texts=['machine learning'], n_results=2)

Chroma auto-embeds your text — no need for external embedding calls.
