And because edges are documents, they carry their own properties, confidence, and timestamps - so the connections are as queryable as the facts themselves.

One question can walk from a person to their team to the decisions they own, in a single step of graph traversal - no join, no second system. chunk embedding vector text extracted_from attribute text confidence valid_from has_source source kind trust belongs_to entity type name embedding vector relation kind (verb) · valid_from · valid_until entity type name embedding vector ## A graph, not a pile of vectors Relationships are first-class, queryable structure - so memory carries meaning, not just proximity in vector space. ### [Typed relationships](https://surrealdb.com/agent-memory/deep-dive) Edges name how things relate, so the graph carries meaning, not just similarity. Learn more ### [Edges are documents](https://surrealdb.com/agent-memory/deep-dive) Each edge carries its own properties, confidence, and timestamps - queryable like any record. Learn more ### [Traversal in one step](https://surrealdb.com/agent-memory/deep-dive) Walk from entity to entity to any depth, without a join or a separate graph store. Learn more ### [Vectors on the same nodes](https://surrealdb.com/agent-memory/recall) Embeddings sit on the graph, so similarity and relationships are ranked together. Learn more ### [Facts stay linked](https://surrealdb.com/agent-memory/memory) New memories attach to the entities they're about, so context compounds instead of fragmenting. Learn more ### [One copy of the data](https://surrealdb.com/agent-memory/deep-dive) The graph, the documents, and the vectors are the same records - nothing to sync. Learn more 02 |ONE SUBSTRATE ## Relationships you can't get from a vector store A flat vector store can tell you two memories read similarly. It can't tell you that this person owns that decision, or that this fact superseded that one. Agent Memory keeps the connections as first-class, queryable structure. ### Meaning, not just similarity Typed edges capture how memories relate, so recall can reason over structure, not only distance in vector space. ### Compounds over time Every new memory links into the existing graph, so the agent's understanding of your world deepens instead of resetting. ### One engine, one query Graph, vector, and document live in one SurrealDB engine, so a single query spans all three with no plumbing between them. ## Keep exploring ### [Typed memory](https://surrealdb.com/agent-memory/memory) The categories that become graph nodes.
