Control VS Code Copilot Chat from your phone — full agent mode with file editing, terminal commands, diagnostics, git diffs, and streaming responses.

What It Does

Mobile Copilot Remote turns your phone into a remote control for GitHub Copilot Chat. Connect via a 6-character room code, and everything you type on your phone is sent to Copilot running in VS Code — with responses streamed back in real-time.

All communication is end-to-end encrypted (X25519 + XSalsa20-Poly1305).

Key Features

Chat with Copilot — Send prompts from your phone, get streamed responses
Agent Mode — Copilot can edit files, run terminal commands, and fix diagnostics on your behalf
Git Integration — View changed files, inline diffs, restore files, switch branches
Terminal Access — Run shell commands in VS Code's integrated terminal
Diagnostics — See workspace errors and warnings
Quick Commands — Predefined shortcuts (explain code, fix errors, write tests, etc.)
E2E Encrypted — All messages encrypted between your devices

Quick Start

The extension connects to a WebSocket relay server and joins a room. Your phone joins the same room. Messages are encrypted on-device and relayed through the server — the relay never sees plaintext.
