ReMe provides AI agents with a unified memory system—enabling the ability to extract, reuse, and share memories across
users, tasks, and agents.
```
Personal Memory + Task Memory + Tool Memory = Agent Memory
```
Personal memory helps "**understand user preferences**", task memory helps agents "**perform better**", and tool memory enables "**smarter tool usage**".
---
## 🚀 Why Teams Choose ReMe
- **Ship smarter agents faster**: Plug-and-play memory primitives with configurable pipelines.
- **Amplify success rates**: Validated lifts up to **+15%** on tool usage and **+9.7%** on multi-turn tasks (see Experiments).
- **Scale with confidence**: Unified memory across users, tasks, and tools—no more babysitting embedding hacks.
- **Deploy anywhere**: HTTP server, MCP service, or direct Python import—same config, same results.
- **Team-ready workflows**: Pre-built libraries, audit trails, and guideline generation keep agents accountable.
> **Quick win:** Try the Quick Start below, then drop a ⭐ if ReMe saves you tokens, time, or both.

## ✨ Architecture Design
ReMe integrates three complementary memory capabilities:
#### 🧠 **Task Memory/Experience**
Procedural knowledge reused across agents
- **Success Pattern Recognition**: Identify effective strategies and understand their underlying principles
- **Failure Analysis Learning**: Learn from mistakes and avoid repeating the same issues
- **Comparative Patterns**: Different sampling trajectories provide more valuable memories through comparison
- **Validation Patterns**: Confirm the effectiveness of extracted memories through validation modules

#### 👤 **Personal Memory**
Contextualized memory for specific users
- **Individual Preferences**: User habits, preferences, and interaction styles
- **Contextual Adaptation**: Intelligent memory management based on time and context
- **Progressive Learning**: Gradually build deep understanding through long-term interaction
- **Time Awareness**: Time sensitivity in both retrieval and integration

#### 🔧 **Tool Memory**
Data-driven tool selection and usage optimization
- **Historical Performance Tracking**: Success rates, execution times, and token costs from real usage
- **LLM-as-Judge Evaluation**: Qualitative insights on why tools succeed or fail
- **Parameter Optimization**: Learn optimal parameter configurations from successful calls
- **Dynamic Guidelines**: Transform static tool descriptions into living, learned manuals

## 📦 Ready-to-Use Memories
ReMe provides pre-built memories that agents can immediately use with verified best practices:
### Available Memories
- **`appworld.jsonl`**: Memory for Appworld agent interactions, covering complex task planning and execution
patterns
- **`bfcl_v3.jsonl`**: Working memory for BFCL tool calls
### Quick Usage
```python
# Load pre-built memories
response = requests.post("http://localhost:8002/vector_store", json={
"workspace_id": "appworld",
"action": "load",
"path": "./docs/library/"
})
# Query relevant memories
response = requests.post("http://localhost:8002/retrieve_task_memory", json={
"workspace_id": "appworld",
"query": "How to navigate to settings and update user profile?",
"top_k": 1
})
```
Python import version
```python
import asyncio
from reme_ai import ReMeApp
async def main():
async with ReMeApp(
"llm.default.model_name=qwen3-30b-a3b-thinking-2507",
"embedding_model.default.model_name=text-embedding-v4",
"vector_store.default.backend=memory"
) as app:
# Load pre-built memories
result = await app.async_execute(
name="vector_store",
workspace_id="appworld",
action="load",
path="./docs/library/"
)
print(result)
# Query relevant memories
result = await app.async_execute(
name="retrieve_task_memory",
workspace_id="appworld",
query="How to navigate to settings and update user profile?",
top_k=1
)
print(result)
if __name__ == "__main__":
asyncio.run(main())
```
## 🧪 Experiments
### 🌍 [Appworld Experiment](docs/cookbook/appworld/quickstart.md)
We tested ReMe on Appworld using qwen3-8b:
| Method | pass@1 | pass@2 | pass@4 |
|--------------|-------------------|-------------------|-------------------|
| without ReMe | 0.083 | 0.140 | 0.228 |
| with ReMe | 0.109 **(+2.6%)** | 0.175 **(+3.5%)** | 0.281 **(+5.3%)** |
Pass@K measures the probability that at least one of the K generated samples successfully completes the task (
score=1).
The current experiment uses an internal AppWorld environment, which may have slight differences.
You can find more details on reproducing the experiment in [quickstart.md](docs/cookbook/appworld/quickstart.md).
### 🧊 [Frozenlake Experiment](docs/cookbook/frozenlake/quickstart.md)
| without ReMe | with ReMe |
|:----------------------------------------------------------------------------------------------------:|:----------------------------------------------------------------------------------------------------:|
| 
| 
|
We tested on 100 random frozenlake maps using qwen3-8b:
| Method | pass rate |
|--------------|------------------|
| without ReMe | 0.66 |
| with ReMe | 0.72 **(+6.0%)** |
You can find more details on reproducing the experiment in [quickstart.md](docs/cookbook/frozenlake/quickstart.md).
### 🔧 [BFCL-V3 Experiment](docs/cookbook/bfcl/quickstart.md)
We tested ReMe on BFCL-V3 multi-turn-base (randomly split 50train/150val) using qwen3-8b:
| Method | pass@1 | pass@2 | pass@4 |
|--------------|---------------------|---------------------|---------------------|
| without ReMe | 0.2472 | 0.2733 | 0.2922 |
| with ReMe | 0.3061 **(+5.89%)** | 0.3500 **(+7.67%)** | 0.3888 **(+9.66%)** |
### 🛠️ [Tool Memory Benchmark](docs/tool_memory/tool_bench.md)
We evaluated Tool Memory effectiveness using a controlled benchmark with three mock search tools using Qwen3-30B-Instruct:
| Scenario | Avg Score | Improvement |
|------------------------|-----------|-------------|
| Train (No Memory) | 0.650 | - |
| Test (No Memory) | 0.672 | Baseline |
| **Test (With Memory)** | **0.772** | **+14.88%** |
**Key Findings:**
- Tool Memory enables data-driven tool selection based on historical performance
- Success rates improved by ~15% with learned parameter configurations
You can find more details in [tool_bench.md](docs/tool_memory/tool_bench.md) and the implementation at [run_reme_tool_bench.py](cookbook/tool_memory/run_reme_tool_bench.py).
