Hippo-memory: Biologically-Inspired Memory System for AI Agents with Decay and Consolidation Features
By
kitfunso
Baker's choice. Dense with flavour, light on filler.
Summary
Hippo-memory is a biologically-inspired memory system for AI agents that addresses the problem of AI agents forgetting everything between sessions. Unlike existing solutions that simply save everything, this system implements memory mechanisms inspired by human cognition including decay, retrieval strengthening, and consolidation. It's designed to be lightweight with zero dependencies and includes features like working memory layers with bounded buffers and importance-based retention. The system aims to create persistent, transferable memories across different AI tools and sessions.
Key quotes
· 4 pulledThe secret to good memory isn't remembering more. It's knowing what to forget.
AI agents forget everything between sessions. Existing solutions just save everything and search later. That's a filing cabinet, not a brain.
Your memories are also trapped. ChatGPT knows things Claude doesn't. Cursor rules don't travel to Codex. Switch tools and you start from zero.
Working memory layer (hippo wm push/read/clear/flush). Bounded buffer (max 20 per scope) with importance-based retention.
