Pinecone

Pinecone is a managed vector database. It stores the numeric representations that AI systems use to find semantically similar content, and answers search queries against them in under a second, without the team using it having to run the underlying infrastructure.

The database itself is serverless and built on object storage, so capacity scales with use rather than with provisioned nodes. Indexes come in dense, sparse and full-text forms, which covers both meaning-based retrieval and straightforward keyword matching in the same system. For workloads that need predictable read performance, Dedicated Read Nodes provide provisioned read capacity instead.

Deployment runs on AWS, Azure and GCP across multiple regions. Bring your own cloud puts a zero-access Pinecone environment inside your own cloud account, so Pinecone itself has no access to what is stored there. Enterprise plans add customer-managed encryption keys, role-based access control is available on some plans, and there is a HIPAA add-on for regulated workloads. Monitoring hooks into Prometheus and Datadog.
