# Memory System
|
|
|
|
How Claude Code and OpenClaw handle cross-session persistence.
|
|
|
|
## Claude Code: File-based memory
|
|
|
|
Claude Code reads files at session start and writes them back on request.
|
|
|
|
**Mechanism:**
|
|
- `CLAUDE.md` files at `~/.claude/CLAUDE.md` (global), repo root, and subdirectories
|
|
- Auto-memory: files listed in `CLAUDE.md` under `memory:` are auto-loaded
|
|
- Project files: any file you explicitly tell Claude to read at session start
|
|
- No background process, no indexing, no database
|
|
|
|
**Properties:**
|
|
- Deterministic: Claude reads exactly what you wrote
|
|
- No semantic search: retrieval is positional, not by meaning
|
|
- Fully transparent: open any file to see what Claude knows
|
|
- Hierarchical: global < project < subdirectory, each level can override
|
|
|
|
## OpenClaw: Hybrid memory
|
|
|
|
OpenClaw maintains memory through a combination of structured logs and vector search.
|
|
|
|
**Mechanism:**
|
|
- Daily markdown logs with structured entries
|
|
- `MEMORY.md` as a curated summary file
|
|
- SQLite-vec or LanceDB for vector storage
|
|
- BM25 + cosine similarity for retrieval (hybrid search)
|
|
|
|
**Properties:**
|
|
- Semantic search: "find notes about authentication" works even without exact keywords
|
|
- Automatic logging: entries written by the agent during execution
|
|
- Higher complexity: requires a running database
|
|
- Retrieval can surface relevant context not explicitly linked
|
|
|
|
## Comparison
|
|
|
|
| Property | Claude Code | OpenClaw |
|
|
|----------------------|---------------------|---------------------------|
|
|
| Storage | Plain files | Files + SQLite/LanceDB |
|
|
| Retrieval | Positional/explicit | BM25 + cosine (hybrid) |
|
|
| Semantic search | No | Yes |
|
|
| Setup complexity | Zero | Moderate |
|
|
| Transparency | Full | Partial |
|
|
| Cross-session | Yes (manual) | Yes (automatic) |
|
|
|
|
## Recommendation
|
|
|
|
For most projects, Claude Code's file-based approach is sufficient. Keep MEMORY.md
|
|
short and curated. Long files degrade quality faster than missing context does.
|
|
|
|
Use this directory (`memory/`) to store any project state that should outlast a session.
