Hippo is an AI agent memory layer inspired by the human hippocampus, designed to manage agent memory with features like default decay, strengthening through use, and full provenance. It integrates with various AI agents and tools, using SQLite for storage and offering a CLI for memory management, ensuring relevant context is always available without overwhelming the agent.
