Physical storage
Separates exclusive, shared, and unknown bytes instead of double-counting cache blobs.
Public beta · Local LLM Inventory for macOS
Know which models are taking your disk space.
WTM scans only the model sources you enable, reconciles provider metadata with physical files, and makes storage, age, completeness, and runtime evidence understandable.
Requires Apple Silicon and macOS 15 or later. Direct distribution; not a Mac App Store product. Installation remains manual.

Release channel
Stable builds are signed and notarized.
Download and install the latest Apple Silicon build directly from Terminal. The command verifies SHA-256 before replacing the app.

One inventory, explicit evidence
Built for model files, not generic disk usage.
Provider context
Connects Ollama manifests and Hugging Face snapshots to weights, configs, age, and confirmed model cards.
Safe actions
Previews cleanup, revalidates files immediately before action, and uses Trash where recovery is possible.
Runtime evidence
Keeps static compatibility, loopback health, and real minimal inference as separate facts.
Reviewed clients
OpenClaw and Unsloth handoffs show the exact executable and argument vector. No Terminal automation.
External volumes
Tracks explicitly enabled internal folders and additional HDDs or SSDs without asking for Full Disk Access.
Support matrix
Provider knowledge stays modular.
| Integration | Inventory | Cleanup | Runtime | Client handoff |
|---|---|---|---|---|
| Ollama | Built in | Provider API | Verify | OpenClaw |
| Hugging Face | Built in | Trash | — | Unsloth |
| Manual folders | GGUF, Safetensors | Trash | llama.cpp | Unsloth |
Privacy and security
Local by default.
- No telemetry in initial releases.
- No Full Disk Access, root helper, microphone, Apple Music, or speech access.
- Inventory is rebuilt from files; model results are not persisted.
- Runtime and client processes use reviewed plans without a shell.
Open architecture
Add providers without weakening the trust boundary.
