Your voice.
Any keyboard.
Speak into your phone. AI generates text, code, emails — copies to clipboard or types into any computer. No drivers. No cloud. Works standalone.
Real demo. No tricks.
Watch BrainJack in action — shot on a phone, unedited.
What we're building.
A 60-second look at the problem BrainJack solves — and why it matters.
Three steps. Zero friction.
Speak
Talk naturally into the BrainJack app. On-device ASR — nothing leaves your network.
Think
AI interprets your intent — generates letters, code, emails, or keyboard actions. Full content creation, not just dictation.
Type
Copied to your clipboard instantly. Or, connect to a computer and keystrokes inject into whatever has focus.
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.
AI Agent Mode
Say "I'm filling out a vet form, write a letter about my dog's shots." The AI generates the full letter. Review on your phone, then send.
Clipboard-First
Works without any computer setup. Speak, AI generates, copied to clipboard. Paste into any app. No service needed.
Run everywhere.
Install on your computer in 30 seconds. Or plug in the USB dongle — zero setup required.

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.
Forms, Letters, Emails
At the vet? Say "write a letter confirming my dog's rabies shot on March 15th." BrainJack generates the full letter, you paste it into the web form. Voice-to-content for real life.
