About Hippo Memory

Make your agent's memory work like a brain. Hippo is long-term memory for coding agents. It's a critical layer for your AI harness that connects across your different tools (Cursor, Claude Code, Codex). It keeps your proprietary data completely local, and it actually learns over time. By strengthening memories each time they are recalled, Hippo preserves what works, lets mistakes decay, and continuously compounds your agents' intelligence.
