What is Vox?

Vox is a GitHub Copilot CLI extension that transforms your terminal sessions into a fully voice-driven experience. Run /vox and a reactive listening orb opens in its own standalone window — speak your turn, and the agent's reply is read back to you. Voice in, voice out, on Windows, macOS, and Linux. Built entirely in pure JavaScript with no build step, Vox works inside the GitHub Copilot app as well as any standard Copilot CLI session.

Who it's for

• Developers with RSI or mobility constraints — keep coding without touching a keyboard, using only your voice to interact with Copilot.
• Multitasking programmers — ask questions and hear answers while keeping your eyes on code, documentation, or a second monitor.
• Accessibility-conscious teams — add a voice layer to Copilot workflows without changing existing tools or requiring special hardware.

Key features

Voice in, voice out

Speak your turn directly into the mic, and Vox streams it into the active Copilot session — no typing, no copy-paste. Every reply is synthesized and read aloud, so your eyes never leave your work.

A reactive orb

The orb is your constant companion: periwinkle and swirling at rest, green and pulsing while listening, amber while the agent thinks, and blue while speaking. Its color and motion tell you exactly what's happening at a glance.

Interrupt and barge in

Tap the orb, press Esc, or hit Interrupt to cut the agent off mid-reply and drop straight back into listening mode. The flow stays uninterrupted — speak, pause, and Vox sends on its own.

Transcript and session management

Open the 📜 panel to read the full conversation history, scroll through it, or clear it without losing your place. Multiple sessions can be live at once, and running /vox elsewhere auto-switches the window to that session.

What stands out

Vox gives Copilot a voice — without ever leaving your terminal.

Most voice tools force you into a browser tab or a separate app. Vox opens as a standalone, chrome-less app window on any OS, using Chromium's app mode so Web Speech APIs work where Electron and native webviews can't. It's a single slash-command away, MIT licensed, with no telemetry and no build step — just pure JavaScript and a one-line install.

Worth checking out if…

You want to talk to your Copilot instead of typing to it — whether for accessibility, convenience, or just to keep your hands on the keyboard and your eyes on the screen. Vox is free, open-source, and works on Windows, macOS, and Linux with zero configuration beyond a single install command.
