Hippo, biologically inspired memory for AI agents

Hippo is a biologically-inspired memory system for AI agents that solves the problem of agents forgetting everything between sessions by implementing seven mechanisms of the human hippocampus, including automatic memory decay, retrieval strengthening, and sleep consolidation. Unlike existing solutions that simply save everything, Hippo intelligently determines what to remember and forget, features cross-tool compatibility allowing shared memory between Claude, Cursor, and other AI platforms, and includes hybrid search capabilities that blend keyword matching with embedding similarity for improved recall quality.
