YourMemory is a new persistent memory layer for AI agents that uses biological decay models to help assistants retain user preferences and context across multiple sessions.

Key Points

• YourMemory functions as a Model Context Protocol (MCP) server, integrating with tools like Claude Desktop, Cline, Cursor, and Windsurf.
• The system utilizes a hybrid architecture combining DuckDB for vector storage, NetworkX for graph-based relationships, and spaCy for natural language processing.
• It features an automated memory decay system based on the Ebbinghaus forgetting curve, where memory strength fades over time unless reinforced by recall.
• Benchmarks show the system achieves 59% recall, reportedly outperforming Zep Cloud by a factor of two on the LoCoMo dataset.
• The software requires no external infrastructure or Docker, supporting local execution with optional PostgreSQL and Neo4j backends for larger datasets.

Why it Matters

By enabling AI agents to maintain long-term context, YourMemory reduces the need for users to repeatedly provide instructions or preferences at the start of every session. This persistent memory layer significantly improves the utility of local AI assistants by allowing them to learn from past interactions and evolve alongside the user's specific workflows.
