aix is a CLI for defining, installing, and syncing AI editor configuration. If you are moving
from Codex to GitHub Copilot, this guide shows what aix can carry over, what the
destination editor calls each feature, and where the destination config lands.
When you are ready to run the move, aix sync codex --to copilot
copies the supported config from Codex into GitHub Copilot. Use the comparison
below first so you know which names, paths, and support differences to expect.
If you want the aix-side definitions first, review rules , prompts , mcp , skills , hooks
.
How to use this guide
- Read across a row to compare the source and destination terms, support, and targets.
- Each scope line shows both what the editor supports and what aix writes today.
- Open the destination editor page at the end if you need every path, note, and terminology detail.
The biggest changes are in rules, prompts, mcp.

aix support
- Native
