Show HN: Hippo, biologically inspired memory for AI agents (github.com) AI

Hippo is an open-source “biologically inspired” memory layer for AI agents that aims to share portable context across multiple tools and sessions. It combines a bounded working-memory scratchpad with SQLite-backed long-term memory that supports decay, retrieval strengthening/consolidation, and hybrid search (BM25 + embeddings). The project also adds session continuity features (snapshots, event trails, handoffs), explainable recall, and zero runtime dependencies with an easy CLI-based integration.
