Dedicated vector database with graph and ontology capabilities on top. Like Pinecone but adds schema-aware relationships between objects.

Dedicated vector database with graph and ontology capabilities on top. Like Pinecone but adds schema-aware relationships between objects.

Stores vectors + structured data with typed schemas

Supports hybrid search: vector similarity + keyword (BM25) in the same query — something Pinecone and Vectorize can't do alone

Built-in modules for auto-vectorization: plug in an embedding model, Weaviate embeds on ingest

Still not a relational database — no SQL, no JOINs in the traditional sense. Key → vector + structured JSON, like Pinecone but richer.
