title: Show HN: AI memory with biological decay (52% recall)
additional: 🧠 "AI Memory Mimics Biological Decay for Smarter Recall"

This innovative AI memory system uses the Ebbinghaus forgetting curve to manage context like a living substrate, assigning a "strength" score to memories that reinforces data with each recall and prunes unused data. By layering a graph over a vector store, it achieves 52% recall accuracy, nearly double that of stateless vector stores, while cutting token waste by 84%. This biologically-inspired approach enables more efficient and effective context management for AI agents handling long-running projects.
