Show HN: AI memory with biological decay (52% recall)

This article introduces an AI memory system inspired by biological decay, using the Ebbinghaus forgetting curve to manage context dynamically. It combines spaced repetition with a graph layer over vector stores, achieving 52% Recall@5 on the LoCoMo dataset and reducing token waste by 84%. The system is built as a local-first MCP server using DuckDB.
