Your voice.
Any keyboard.
Control any computer from your phone. Voice-to-keystroke across SSH sessions, remote machines, and legacy systems. No drivers. No cloud. No limits.
Three steps. Zero friction.
Speak
Talk naturally into the BrainJack app. On-device ASR — nothing leaves your network.
Think
AI interprets your intent, formats data, resolves macros, and queues keystrokes.
Type
Keystrokes inject into whatever window has focus. USB HID or network agent — your choice.
Built different.
Not another clipboard app. BrainJack is a universal HID bridge that works where nothing else can.
Universal USB HID
Appears as a standard keyboard. Works with BIOS, login screens, legacy DOS, anything that takes keyboard input since 1995.
HIPAA-Local by Default
All voice processing stays on your network. Zero cloud dependency. Token auth, TLS, audit logging built in.
Every Platform
Windows (SendInput), macOS (osascript), Linux X11 (xdotool), Linux Wayland (ydotool). One agent, all OSes.
Zero Install on Target
With the ESP32 dongle, the target machine needs nothing. No drivers. No software. No admin rights. Just USB.
Command Sheets
One-tap macros for vim, tmux, emacs, VS Code, shell. Tool-specific palettes, color-coded, OS-aware.
Open Ecosystem
Compatible with ESP32-S3, Flipper Zero, any WebSocket client. Source-available under BSL. Build on it.
Run everywhere.
Install the agent on your target machine in 30 seconds. Or flash the ESP32 dongle for zero-install deployment.

Your phone is the remote.
Voice input, virtual trackpad, macro sheets, multi-device management. All from your pocket.
Your phone. Every machine.
Control any machine from your phone. SSH, code, manage servers — all by voice.
Your Phone is a Terminal
SSH into 10 servers from the couch. One-tap vim macros, tmux splits, shell combos. Voice-dictate code, commit messages, config files. Command sheets built for the terminal-obsessed.
Multi-Machine from Your Pocket
Switch between your work Mac, home Linux box, and a cloud VM — all from one phone. Each device remembers its OS, macros, and auth token. You're always one tap away.
Open Hardware, Open Firmware
Flash an ESP32-S3 or your Flipper Zero WiFi board. Full firmware on GitHub. Build your own voice-controlled anything for the cost of a coffee.

The agent is free. The firmware is open. The future is voice.
