A small, always-on-top window that live-mirrors something else on your Mac: an app window, a region of a screen, or a browser tab. It floats above everything, follows you across Spaces, and stays perfectly in sync with the real thing.
No, portals are view-only on purpose. A portal never steals focus, clicks, or keystrokes from the app you're actually working in. When you want to act on what you see, switch over. Until then, just watch.
