Features

Bridge & capture

• USB-A host port — accepts any standard USB keyboard, no drivers.
• BLE 5.0 peripheral output — auto-spoofs the plugged-in keyboard's identity.
• Inline keylogging — every scancode forwarded is also logged.
• Per-keyboard calibration — accurate text reconstruction across QWERTY, QWERTZ, AZERTY, custom layouts.

Detection & rules

• Replace rules — ("REPLACE")["trigger"] = "action" syntax for substitution and event triggers.
• Keyword detection — fires on configured exact-match strings.
• Regex detection — pattern-match emails, credentials, structured input.
• Action types — keyboard primitives (KEY_*), media primitives (MEDIA_*), text output, prefixed-print.

Wireless control

• WiFi AP (... ZT, WPA2, default ZeroTrace) hosting the web UI at 192.168.4.1.
• WiFi STA mode — join an existing network and control from the same LAN.
• Live web UI — instant rule updates, no firmware reflash.

Identity

• Auto-spoof BLE identity — reads USB descriptors from the plugged keyboard, replicates name/VID/PID over BLE.
• Manual override — set custom BLE name, manufacturer data, appearance code.
• Battery service exposure — host sees a battery percentage like a real BLE keyboard.

Storage & maintenance

• 4 MB on-device filesystem — calibration profiles, rule sets, capture exports.
• Browser-based Web Flasher — no install, runs in Chrome or Edge.
• Cross-platform tooling — Windows, macOS, Linux for the Companion app.
