Yosei Turns iPhone Duo Into A Tiny MacBook, Brings Mac Agent Monitoring To iPhone And iPad

If you’re used to leaving your Mac running and agents getting stuff done, you’ll know that monitoring them can be difficult. That’s where an app called Yosei may have the answer.

Made for the AGI era, the app runs on your iPhone or iPad and allows you to seamlessly monitor your agents from afar via screen sharing.

You can even take over using the touch-based interface if you need to, otherwise the agent works away and you don’t even need to have a monitor connected for any of this to work.

Whereas other screen sharing apps copy the shape and size of your Mac’s screen, Yosei generates a new screen based on the device that you’re using.

That means you’ll get a different screen if you’re using the iPhone Duo’s outer display, and another one if you use the inner display. The same applies to iPhones in landscape, iPhones in portrait, and even iPads.

Not just that, it supports “seated post” on iPhone Duo, essentially turning it into a tiny MacBook of sorts.

This way, you make full use of the screen real estate at hand. You can even use your iPhone or iPad as a trackpad for more fine-grained control of your Mac’s display. Audio is also supported, and you can expect a crisp view and up to 120fps frame rates as well.

You can sign up for the public beta of Yosei right now, and there’s an intro video to give you an idea of what you can expect, too.
