Can I Run AI Culling on Both My Windows Desktop and MacBook?

What cross-platform support actually means

Cull AI Studio is built for both Windows and macOS, so the choice of desktop versus laptop, or PC versus Mac, does not lock you out of either. A photographer with a Windows desktop for heavy editing and a MacBook for travel can install and use the app on both, signing in with the same account on whichever machine she is working from that day.

The part that is not simultaneous

The account model allows one signed-in device at a time. If you sign in on your MacBook while already signed in on your Windows desktop, the new sign-in bumps the older one; you are not running two active sessions side by side. This is a real constraint worth planning around if you regularly switch machines mid-project, and it differs from a model where every device stays logged in indefinitely.

What actually follows you between machines

Because your trained model file and your app settings sync through the account, switching from desktop to laptop is not a fresh start. Sign in on the new machine, and the personal model built from your past corrections, along with your app settings, comes with you. Your photos themselves are never part of that sync, since they never leave whichever machine you are culling on in the first place; only the model and settings travel.

A concrete example

A photographer culls most weddings at her studio on a Windows desktop, where her personal model has trained on hundreds of past decisions. Before a destination wedding, she signs in on her MacBook to cull on location; that sign-in bumps her desktop's session, and her trained model and settings are already there waiting, since they sync through her account rather than living only on the desktop. When she gets home and signs back in on the desktop, that session becomes active again and the MacBook's session is bumped in turn.

What this means for planning your workflow

• Expect a sign-in handoff, not simultaneous use. Plan around one active device at a time rather than treating both machines as always logged in.
• Your model and settings are safe to switch on. You do not lose training progress by moving between a desktop and a laptop.
• Your photos stay on whichever machine culls them. Since photos are never uploaded, moving between machines does not move your photo files; you still need your own process for getting a project's files to wherever you are culling next.

Honest limitations

The one-device-at-a-time model means you cannot run a cull on your desktop while simultaneously reviewing a different project on your laptop under the same account. If your workflow depends on two machines being active in parallel, this is a real constraint to plan for rather than a setting you can configure around.

How Cull AI Studio handles this

Cull AI Studio supports Windows and macOS, and one signed-in device is allowed at a time, with a new sign-in bumping the oldest one. Your trained model and app settings sync across machines through your account, so your personal model's progress is not tied to a single computer. Culling itself remains fully local to whichever machine is active, so your photos never leave that device regardless of how many machines your account has been used on.
