# Mem0 Local - Sovereign Memory Provider
|
||
|
|
|
||
|
|
Local-only memory provider using ChromaDB. No API key required - all data stays on your machine.
|
||
|
|
|
||
|
|
## How It Differs from Cloud Mem0
|
||
|
|
|
||
|
|
| Feature | Cloud Mem0 | Local Mem0 |
|
||
|
|
|---------|-----------|------------|
|
||
|
|
| API key | Required | Not needed |
|
||
|
|
| Data location | Mem0 servers | Your machine |
|
||
|
|
| Fact extraction | Server-side LLM | Pattern-based heuristics |
|
||
|
|
| Reranking | Yes | No |
|
||
|
|
| Cost | Freemium | Free forever |
|
||
|
|
|
||
|
|
## Setup
|
||
|
|
|
||
|
|
```bash
|
||
|
|
pip install chromadb
|
||
|
|
hermes config set memory.provider mem0-local
|
||
|
|
```
|
||
|
|
|
||
|
|
Or manually in ~/.hermes/config.yaml:
|
||
|
|
```yaml
|
||
|
|
memory:
|
||
|
|
provider: mem0-local
|
||
|
|
```
|
||
|
|
|
||
|
|
## Config
|
||
|
|
|
||
|
|
Config file: $HERMES_HOME/mem0-local.json
|
||
|
|
|
||
|
|
| Key | Default | Description |
|
||
|
|
|-----|---------|-------------|
|
||
|
|
| storage_path | ~/.hermes/mem0-local/ | ChromaDB storage directory |
|
||
|
|
| collection_prefix | mem0 | Collection name prefix |
|
||
|
|
| max_memories | 10000 | Maximum stored memories |
|
||
|
|
|
||
|
|
## Tools
|
||
|
|
|
||
|
|
Same interface as cloud Mem0:
|
||
|
|
|
||
|
|
| Tool | Description |
|
||
|
|
|------|-------------|
|
||
|
|
| mem0_profile | All stored memories about the user |
|
||
|
|
| mem0_search | Semantic search by meaning |
|
||
|
|
| mem0_conclude | Store a fact verbatim |
|
||
|
|
|
||
|
|
## Data Sovereignty
|
||
|
|
|
||
|
|
All data is stored in $HERMES_HOME/mem0-local/ as a ChromaDB persistent database. No network calls are made.
|
||
|
|
|
||
|
|
To back up: copy the mem0-local/ directory.
|
||
|
|
To reset: delete the mem0-local/ directory.
|
||
|
|
|
||
|
|
## Limitations
|
||
|
|
|
||
|
|
- Fact extraction is pattern-based (not LLM-powered)
|
||
|
|
- No reranking - results ranked by embedding similarity only
|
||
|
|
- No cross-device sync (by design)
|
||
|
|
- Requires chromadb pip dependency (~50MB)
