ZeroTrace Companion
Overview
The legacy ZeroTrace desktop app, now focused on BLELogger. HID and AirLeak are managed from the ZeroTrace mobile app.
ZeroTrace Companion is the legacy desktop app. HID and AirLeak are now managed from the ZeroTrace mobile app, the desktop app no longer drives those devices. Companion remains useful for BLELogger, and you can still download it, but for HID and AirLeak start with the mobile app instead.
ZeroTrace Companion is the original desktop application for ZeroTrace devices. It now centers on ZeroTrace BLELogger, plug a BLELogger into your computer over USB, open Companion, and you have a local management interface with a terminal and the offline AI assistant, without a single browser tab.
Companion runs entirely on your machine. The HID and AirLeak modes described below are legacy, those devices have moved to the mobile app.
The everyday path for HID and AirLeak is now mobile. Pair a HID or AirLeak device with the ZeroTrace mobile app over Bluetooth. For BLELogger, Companion (or the device's built-in Web UI) is the way.
What Companion gives you
| Capability | What it does |
|---|---|
| Auto device detection | Scans every COM port on your machine, identifies which ZeroTrace devices are connected, and surfaces them in the picker |
| HID dashboard | Real-time device info, firmware, storage, BLE name, Wi-Fi state, for any connected ZeroTrace HID |
| Terminal | Direct command-line access to the connected device for power users and troubleshooting |
| AirLeak workspace | Full live-monitoring suite for ZeroTrace AirLeak, Wi-Fi and BLE devices, sessions, alerts, library, insights, tracking |
| Offline AI assistant | Local LLM integration with device-aware tool calling, ask the assistant about your data without anything leaving your machine |
| Sessions library | Capture, save, and replay every observation a connected AirLeak device makes |
| Known-device library | Persistent catalog of devices you have seen before, with merged identity across MAC randomisation |
| Cross-platform | Windows, macOS Intel and Apple Silicon, Linux |
Three modes in one app
Companion adapts to whatever device is connected. The HID and AirLeak modes below are legacy, kept for reference; both device families are now driven from the mobile app.
Plug in a ZeroTrace HID. Companion shows the HID dashboard with device info and quick actions, plus the terminal for raw command access. Use it to inspect device state, manage settings, push files, or run scripts.
Privacy posture
Three guarantees that match the rest of the ZeroTrace product line:
- No telemetry. Companion does not send analytics, error reports, or usage data anywhere.
- No cloud dependency. Companion runs entirely on your machine. Device data never leaves your hardware unless you explicitly export it.
- AI runs locally. The AI assistant uses a local LLM on your own machine, your prompts and your device data never reach a third-party LLM provider.
Supported devices
| Device | Connection | Status in Companion |
|---|---|---|
| ZeroTrace BLELogger | USB COM port | Supported, terminal + AI assistant |
| ZeroTrace HID | USB COM port | Legacy, use the mobile app |
| ZeroTrace AirLeak | USB COM port (high-speed) | Legacy, use the mobile app |
| Any custom firmware | USB COM port | Configurable via custom device profile |
Companion's HID dashboard and AirLeak workspace are legacy and no longer the supported path. Manage HID and AirLeak devices from the ZeroTrace mobile app over Bluetooth. Companion stays relevant for BLELogger.
Where to start
If you are using BLELogger with Companion:
- Installation, get the binary on your machine.
- First launch, what to expect the first time you open it.
- Connecting devices, plug in your BLELogger and verify it shows up.
For HID and AirLeak, use the mobile app instead:
- HID owners → HID control in the mobile app.
- AirLeak owners → AirLeak in the mobile app.
- BLELogger owners → Terminal and the AI Assistant.
