Honcho is open-source AI memory for agents. It remembers every user across sessions and tools, from Claude Code to your own agent. State of the art on LongMem.

Honcho is an entity which serves as the main antagonist of The Archives, being the subfloor's boss, both literally and gameplay-wise.

Honcho is memory infrastructure for building stateful agents that understand changing people, agents, groups, projects, and ideas over time. Store messages and events, let Honcho reason in the background, then query peer representations, session context, search results, or natural-language insights from any model or framework.

Find your photos with a selfie. Upload a selfie and Honcho builds a personal gallery in seconds, showing just the photos you appear in.

Honcho is an AI-native memory backend that adds dialectic reasoning and deep user modeling on top of Hermes's built-in memory system. Instead of simple key-value storage, Honcho maintains a running model of who the user is — their preferences, communication style, goals, and patterns — by reasoning about conversations after they happen.

A relic of the large U.S. presence in Japan in the years following World War II, the word honcho comes from the Japanese word hanchō meaning “leader of the squad, section, group.”

Honcho gives you maximum control over your agent’s context and memory. The data model is flexible and composable, the reasoning backend is powerful yet cost-effective, and everything is built to give developers levers to manage token usage, latency, and reasoning depth.
