# 🦛 Hippo **Stop re-teaching your agent.** 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.

Search is BM25 out of the box, with no model and no network call; embeddings are an optional install. `hippo init` installs hooks for Claude Code and OpenCode, adds 2 hooks to Codex's `hooks.json` when Codex is installed (Codex runs them once you trust them in `/hooks`), and adds instructions to an existing `AGENTS.md` for Codex, Cursor, OpenClaw and Pi. Any MCP client can connect. Mark a memory wrong and it ranks lower; run `hippo supersede` and the old fact leaves recall. Zero runtime deps. Install it, then run `hippo init` inside one project. Init creates the project's `.hippo/` store and adds a block to the `CLAUDE.md` or `AGENTS.md` already there. On your machine it adds hooks for the agents it finds, such as Claude Code's in `~/.claude/settings.json`, and a daily 6:15am run.
