What BrainJack does
Your phone becomes a voice-powered AI keyboard for any computer. Speak, generate, type — anywhere.
Voice to keystrokes
Speak on your phone. Text types on your computer — real keystrokes into whatever app has focus. Not a paste, not a clipboard hack.
AI agent, not dictation
"Write a professional email declining this meeting." BrainJack generates full content from a prompt. Review on your phone, edit if needed, send with one tap.
Custom agents & prompt management
Build reusable prompt templates — email writer, code commenter, translator, tone adjuster. Save them, organize them, trigger them by voice.
Software or hardware
Install the service for full features. Or plug in a USB dongle — zero install on the target machine. Works on BIOS screens, login prompts, air-gapped systems.
SSH terminal
Full terminal from your phone. Manage servers, run commands, check logs. Landscape mode, device profiles, one-tap macros for vim/tmux/emacs.
Bring your own keys
Your LLM, your ASR model, your API keys. OpenAI, Anthropic, Ollama, vLLM, local Whisper — whatever you want. We don't touch your data.
Fully local
Phone to computer over WiFi. No cloud, no accounts, no tracking. Your voice stays on your network. HIPAA-friendly by design.
Open source
Apache 2.0. Read the code, audit it, fork it, run it forever. View on GitHub
