# PowerMem

**Persistent, self-evolving memory for AI agents and applications.**

*English · [中文](README_CN.md) · [日本語](README_JP.md)*

PowerMem combines vector, full-text, and graph retrieval with LLM-driven memory extraction and Ebbinghaus-style time decay. It ships **two-layer Experience + Skill distillation** for self-evolving memory, multi-agent isolation, user profiles, and multimodal signals (text, image, audio).

## Why PowerMem

AI agents need more than chat history. Context windows are finite, and naive "save everything" memory quickly becomes noisy, expensive, and hard to retrieve from. PowerMem turns conversations, actions, and feedback into structured long-term memory that can be searched, updated, decayed, and shared across agents.

What makes PowerMem different:

- **Intelligent memory lifecycle** — LLM-driven extraction, update, merge, and Ebbinghaus-style decay keep memories useful instead of becoming static note dumps.
- **Self-evolving two-layer memory** — Experience + Skill distillation lets agents learn reusable workflows from interactions, not just recall facts. See [Experience + Skill distillation](docs/examples/scenario_6_sub_stores.md).
- **Hybrid retrieval out of the box** — vector, full-text, graph, and recency signals work together in one memory layer without custom glue.
- **Production-ready integration surface** — the same backend supports the Python SDK, HTTP server, MCP, CLI, and AI client plugins. See the [architecture overview](docs/architecture/overview.md).

Use PowerMem when you are building long-running agents, copilots, or multi-agent systems that must remember users, projects, decisions, preferences, and learned workflows across sessions.

## Benchmarks

### [LOCOMO](https://github.com/snap-research/locomo)

| Metric | PowerMem | Baseline | Improvement |
|--------|----------|-------------------------|-------------|
| Accuracy | **87.79%** | 52.9% | **+65.9%** |
| Search p95 latency | **1.44 s** | 17.12 s | **-91.6%** |
| Tokens | **~0.9 k** | 26 k | **-96.5%** |

### [AppWorld](https://github.com/StonyBrookNLP/appworld)

| Metric | PowerMem | Baseline | Improvement |
|--------|----------|-------------------------|-------------|
| Pass | **39%** | 24% | **+62.5%** |
| Avg steps | **6.2** | 9.5 | **-34.7%** |
| Total tokens | **1.74 M** | 2.56 M | **-32.0%** |

Reproduce: [`benchmark/`](benchmark/). Under the hood: **two-layer Experience + Skill distillation + 4-way hybrid retrieval + LLM auto-merge** (API: `memory.distill_all() / add_skill / add_experience / search_*`, demo [`examples/experience_skill_usage.py`](examples/experience_skill_usage.py)).

---

## Integrations — pick your client, copy one line

PowerMem ships first-party plugins and setup guides for the most common AI clients. All of them point at the same backend (HTTP server, MCP server, or local `pmem` CLI) — no per-client schema rewrites. All agents share the same memory server.

### SDKs & apps

| App / framework | Details |
|-----------------|---------|
| Python SDK | `pip install powermem`, see [Quick start](#quick-start-python-sdk) |
| LangChain / LangGraph | `pip install powermem`, see [LangChain guide](docs/integrations/langchain.md) |
| AgentScope | Connect to `powermem-mcp` with AgentScope's MCP client, see [AgentScope guide](docs/integrations/agentscope.md) |
| Go apps | [SDKs](#sdks) |
| Java apps | [SDKs](#sdks) |
| TypeScript apps | [SDKs](#sdks) |
| Any MCP client | `powermem-mcp sse` (default :8848), see [MCP client guide](docs/integrations/mcp_client.md) |
| HTTP REST apps | `powermem-server --host 0.0.0.0 --port 8848`, see [API server](docs/api/0005-api_server.md) |

### OpenClaw (ClawdBot)

[OpenClaw](https://github.com/openclaw/openclaw) gains long-term memory through the [`memory-powermem`](https://github.com/ob-labs/memory-powermem) plugin.

```bash
openclaw plugins install memory-powermem
```

Defaults to **CLI mode** — the plugin invokes a bundled `pmem` against SQLite under `~/.openclaw/`, using the model OpenClaw already injects. No separate server, no extra `.env`. Switch to **HTTP mode** when a team-shared PowerMem API is preferred (see the plugin's README for `requestConfig.memory_db`).

Full guide: [OpenClaw integration](docs/integrations/openclaw.md).

<div align="center">

<img src="docs/images/openclaw_powermem.jpeg" alt="PowerMem with OpenClaw" width="640"/>

</div>

### Claude Code

#### Fastest path — let Claude Code set itself up

First download the code and enter the directory:

```bash
git clone https://github.com/oceanbase/powermem
cd powermem
```

Then open Claude Code in your terminal and paste this one line:

```text
Read and follow apps/claude-code-plugin/SETUP.md to set up PowerMem memory for Claude Code.
```

Claude Code reads [`apps/claude-code-plugin/SETUP.md`](apps/claude-code-plugin/SETUP.md), asks you for the few required secrets, and wires everything up end-to-end.

#### Manual setup

Prefer to wire it by hand? See the full walkthrough — environment variables, MCP mode, the `remember` / `recall` skills, Windows hooks, troubleshooting, and uninstall — in **[docs/integrations/claude_code.md](docs/integrations/claude_code.md)**.

### Cursor, VS Code, Windsurf, GitHub Copilot, Qoder

#### Recommended setup — let your IDE agent set it up

First download the code and enter the directory:

```bash
git clone https://github.com/oceanbase/powermem
cd powermem
```

Then open the AI agent window in your IDE and paste this one line:

```text
Read and follow apps/vscode-extension/SETUP.md to setup PowerMem
```

The agent follows [`apps/vscode-extension/SETUP.md`](apps/vscode-extension/SETUP.md): it prefers a reusable `powermem-server` HTTP API backend, falls back to MCP-only only when HTTP is unavailable, and configures the current IDE/client instead of unrelated tools.

#### Manual setup

Prefer to wire it by hand? Use the per-IDE guide:

| Client | Details |
|--------|---------|
| VS Code | [`docs/integrations/vs_code.md`](docs/integrations/vs_code.md) |
| Cursor | [`docs/integrations/cursor.md`](docs/integrations/cursor.md) |
| Windsurf | [`docs/integrations/windsurf.md`](docs/integrations/windsurf.md) |
| GitHub Copilot | [`docs/integrations/github_copilot.md`](docs/integrations/github_copilot.md) |
| Qoder | [`docs/integrations/qoder.md`](docs/integrations/qoder.md) |

The same extension also provides **Query memories**, **Add selection to memory**, **Quick note**, and a status-bar **Dashboard**. See [`apps/vscode-extension/README.md`](apps/vscode-extension/README.md) and the full [VS Code guide](docs/integrations/vs_code.md).

### Any MCP client 

For Claude Desktop, Codex, Cline, OpenCode, Roo Code, Goose, or any other MCP-compatible client. please use MCP Client mode. 
First download the code and enter the directory:

```bash
git clone https://github.com/oceanbase/powermem
cd powermem
```

Then open the AI agent window in your MCP client or IDE and paste this one line:

```text
Read and follow apps/mcp-client/SETUP.md to setup PowerMem
```

The agent follows [`apps/mcp-client/SETUP.md`](apps/mcp-client/SETUP.md): it uses `powermem-mcp` directly, prefers SSE on port `8848`, falls back to streamable HTTP or stdio only when needed, and configures only the target MCP client.

Prefer to wire it by hand? Use the [Generic MCP client guide](docs/integrations/mcp_client.md). To remove the integration later, follow [`apps/mcp-client/UNINSTALL.md`](apps/mcp-client/UNINSTALL.md). Exposed tools: `add_memory`, `search_memories`, `get_memory_by_id`, `update_memory`, `delete_memory`, `delete_all_memories`, `list_memories`. Full reference: [MCP Server](docs/api/0004-mcp.md). Client-specific notes: [Cline](docs/integrations/cline.md), [Codex](docs/integrations/codex.md), and [OpenCode](docs/integrations/opencode.md).

### LangChain & LangGraph

```bash
pip install powermem langchain langchain-openai
```

End-to-end runnable demos:

- [LangChain healthcare bot](examples/langchain/README.md)
- [LangGraph customer service bot](examples/langgraph/README.md)

Full framework guide: [LangChain and LangGraph integration](docs/integrations/langchain.md).

### AgentScope

PowerMem works with AgentScope through MCP. Start `powermem-mcp`, then connect
to it with AgentScope's MCP client so AgentScope workflows can use `add_memory`,
`search_memories`, and the other memory tools.

Full framework guide: [AgentScope integration](docs/integrations/agentscope.md).

### SDKs

| Language | Package |
|----------|---------|
| Python | `pip install powermem` (this repo) |
| Go | [`ob-labs/powermem-go`](https://github.com/ob-labs/powermem-go) |
| Java | [`ob-labs/powermem-java`](https://github.com/ob-labs/powermem-java) |
| TypeScript | [`ob-labs/powermem-ts`](https://github.com/ob-labs/powermem-ts) |

---

## Quick start (Python SDK)

**Prerequisites:** Copy [.env.example](.env.example) to `.env` and set your **LLM** API key — that is the only required credential. For zero-config local storage, install the `seekdb` extra (`pip install "powermem[seekdb]"`, or combine it with `server` / `mcp`) so the default **OceanBase** provider can boot **embedded seekdb** on disk. Without `seekdb`, set `OCEANBASE_HOST` to point at a remote OceanBase cluster, or switch to `sqlite` / `postgres`. The default embedder is a local `all-MiniLM-L6-v2` model (384 dims) that needs no API key and auto-downloads on first use. Need to tune providers or unlock advanced features? Copy [.env.example.full](.env.example.full) instead — it documents every available knob, grouped by component. After install, `pmem config init` walks you through the same setup interactively. See [Getting started](docs/guides/0001-getting_started.md).

### Install

```bash
# Core only (SDK; no optional CLI/server/MCP/seekdb)
pip install powermem

# With CLI (pmem / powermem-cli)
pip install "powermem[cli]"

# With HTTP API server only (powermem-server; does not install seekdb)
pip install "powermem[server]"

# With MCP server only (powermem-mcp; does not install seekdb)
pip install "powermem[mcp]"

# With seekdb for zero-config local storage/embedder
pip install "powermem[seekdb]"

# HTTP API server + seekdb
pip install "powermem[server,seekdb]"

# MCP server + seekdb
pip install "powermem[mcp,seekdb]"

# Common full local install
pip install "powermem[cli,server,mcp,seekdb]"
```

For zero-install MCP clients such as Cursor, Codex, Claude Desktop, Cline, or
Goose, use the wrapper package:

```bash
uvx powermem-mcp
```

The `powermem-mcp` wrapper is version-locked to the main `powermem` release and
installs `powermem[mcp,seekdb]` for the same version. If `uv` has cached an older
tool environment, refresh it explicitly:

```bash
uvx --refresh --upgrade powermem-mcp
```

### SDK

Run from a directory that contains your configured `.env`:

```python
from powermem import Memory, auto_config

memory = Memory(config=auto_config())

memory.add("User likes coffee", user_id="user123")

for r in memory.search("user preferences", user_id="user123").get("results", []):
    print("-", r.get("memory"))
```

More patterns: [Getting Started](docs/guides/0001-getting_started.md).

### CLI (`pmem`, 1.0+)

```bash
pmem memory add "User prefers dark mode" --user-id user123
pmem memory search "preferences" --user-id user123
pmem shell                           # interactive REPL
```

Full reference: [CLI usage](docs/guides/0012-cli_usage.md).

### HTTP API server + Dashboard

Uses the same `.env` as the SDK. Dashboard is served under `/dashboard/`.

```bash
powermem-server --host 0.0.0.0 --port 8848
```

On an interactive local terminal, the server automatically opens the Dashboard in your default browser once it is ready. You can also open `http://localhost:8848/dashboard/` manually to browse memories, view analytics, and monitor system health. Use `--no-open-browser` to disable auto-open, or `--open-browser` when output is redirected. Browser opening is skipped in CI, containers, SSH sessions, headless environments, and when Dashboard assets are unavailable. See the [Web Dashboard Guide](docs/guides/0013-dashboard.md) for a complete walkthrough.

Docker / Compose: see [API Server](docs/api/0005-api_server.md) and [Docker & deployment](docker/README.md). The official image is `oceanbase/powermem-server:latest`.
