## What it is
An unofficial Emacs plugin for GitHub Copilot that provides inline ghost-text completions, a chat interface, and Next Edit Suggestions. It communicates with the official Copilot language server over JSON-RPC using rpc.el, sharing a single server across all buffers.

## Use cases
- get AI code completions in Emacs
- use GitHub Copilot inside Emacs
- chat with Copilot from my editor
- accept inline code suggestions with tab
- set up Copilot in Emacs without Node.js
- get next edit suggestions while coding in Emacs

## When to choose
- you use Emacs as your primary editor and have a GitHub Copilot subscription (or the free tier)
- you want native-feeling inline completions and Copilot chat without leaving Emacs
- you prefer a lightweight rpc integration over a full LSP client setup

## When to avoid
- you use Vim, Neovim, VS Code, or another editor instead of Emacs
- you don't have access to GitHub Copilot
- you want a fully local/offline AI assistant rather than GitHub's cloud service
- you're on Emacs 26 or older
