Cut token waste by 84% with self pruning MCP memory
YourMemory is an innovative AI tool designed to optimize how agents manage and recall information. Unlike traditional systems that either forget everything or hoard excessive data, YourMemory applies biological principles, specifically the Ebbinghaus curve, to intelligently prune unnecessary context. This results in a leaner, more relevant memory footprint that enhances reasoning and reduces token waste by up to 84%. Suitable for developers, AI practitioners, and organizations seeking more efficient memory management, it ensures critical information is retained while irrelevant data is discarded, leading to sharper, more accurate AI outputs. Its self-pruning MCP memory system and graph engine for discovering forgotten insights make it a standout choice for those wanting to improve AI reasoning without sacrificing important details. Plus, its local operation guarantees privacy and security, making it ideal for sensitive applications.
