FAQPage Schema
How do I set up a local vector database for storing AI embeddings?▼

To set up a local vector database for AI embeddings, you can install the chromadb package and initialize a collection to begin storing embeddings and metadata locally without relying on external services.

What is the best way to add memory to AI applications using semantic search?▼

The best way to add memory to AI applications using semantic search is by using an open-source vector database to store and retrieve embeddings efficiently with metadata filtering.

Does Chroma work with LangChain and LlamaIndex for RAG workflows?▼

Yes, Chroma works seamlessly with LangChain and LlamaIndex, providing local persistent storage for embeddings and metadata to enable fast document retrieval within RAG workflows.

Can I filter embeddings by metadata when doing similarity search?▼

Yes, you can filter embeddings by metadata during similarity search. Chroma provides fast similarity search, document retrieval, and metadata filtering across notebooks and production pipelines.

Do I need an external service to run a vector database for experiments?▼

No, you do not need an external service to run a vector database for experiments. Chroma provides an open-source, self-hosted vector store that enables fast similarity search locally.

What limitations exist when using an open-source vector database for AI memory?▼

Limitations of an open-source vector database for AI memory include the requirement to self-host and manage the infrastructure, though Chroma mitigates this with a simple four-function API and language-agnostic client support.
