Memgraph is a high performance, in memory graph database for real time AI context and graph analytics at scale. Vector search identifies what is similar. Graph reasoning reveals what is connected by traversing relationships, dependencies, and hierarchies that similarity alone cannot capture. Modern AI systems need both. Memgraph provides the graph layer that delivers precise structural context, full auditability, and sub millisecond performance. It powers GraphRAG pipelines, AI memory systems, and agentic workflows through a single high performance layer built for connected, structured context. The same architecture also supports real time graph analytics for fraud detection, network analysis, infrastructure monitoring, and other operational workloads where milliseconds directly affect outcomes. NASA uses Memgraph to connect people, skills, and projects across the agency in a queryable knowledge graph for real time expert discovery and workforce planning. Cedars Sinai uses it to connect genes, drugs, and clinical pathways in an Alzheimer’s knowledge graph spanning more than 230,000 entities, supporting drug repurposing research and multi hop biomedical reasoning. Across cybersecurity, finance, retail, and other knowledge intensive industries, organizations use Memgraph to turn connected data into real time insight.
