Ensemble
Run multiple isolated profiles of ChatGPT, Claude, and Gemini on your Mac — each with its own login, all signed in at once.
macOS 14 or later · Apple Silicon · 14-day free trial, no account needed
One Mac, several accounts
Signing out and back in to move between a work account and a personal one is a bad way to spend the day. Ensemble keeps each account in its own profile — named, color-coded, permanently signed in — and launches them side by side.
ChatGPT
Each profile gets its own CODEX_HOME, so logins and sessions stay separate.
Claude
Each profile runs with its own data directory — separate accounts, running together.
Gemini
Opens as its own app window through Chrome, with a per-profile browser profile.
How it works
Ensemble launches the real apps you already have installed. It isn't a wrapper, a web view, or a repackaged copy — each profile simply gets its own data directory, the same mechanism the apps use themselves. Your logins stay on your Mac.
A menu-bar switcher lists every profile, shows which are running, and brings one forward with a click. Ensemble stays out of the way otherwise.
