Built for AI Applications

Everything you need to build intelligent systems that understand context and relationships.

Hyperedges

Connect any number of nodes in a single edge. Model complex N-ary relationships that traditional graphs cannot express.

Multi-hop Paths

Traverse relationships across multiple hops to discover hidden connections. Enable reasoning chains for RAG pipelines.

Hybrid Search

Combine vector similarity with graph traversal. Find semantically related knowledge within relationship context.

Memory Types

Built-in support for facts, entities, episodes, procedures, preferences, and goals. Structure knowledge the way humans think.

Bi-Temporal

Track when facts were true and when they were recorded. Query knowledge as it existed at any point in time.

Native Embeddings

Store and query vector embeddings directly on nodes and edges. Powered by efficient cosine similarity search.
