Unlike vector databases or RAG, it extracts structured facts, builds a knowledge graph, and applies biological forgetting curves to simulate real memory. The system exposes three core actions: ingest, recall, and reflect. It claims the #1 spot on LoCoMo benchmarks, 2x faster performance than Mem0, and 97% cost reduction at scale. ## Full article daily.dev links to this article rather than hosting it.
