Click a shortcut. Each one opens its own ChatGPT, side by side.

A work plan, a personal plan, one app.

The ChatGPT app keeps one sign-in, and Codex keeps one settings folder. Switching accounts means signing out, and your Codex setup is shared between them.

One sign-in at a time.Every switch is a sign-out and a sign-in.
One Codex setup.Skills and history from one account show up in the other.
Client work next to your own.Hard to keep apart when both live in one app.
