Attach the current window to another window

From the Windows App Community server on Discord:

And here comes my secret sauce: floating attachable AI panel for any window
So you can have a native AI chat panel for any app whether that app has its own AI or not, and you can resize it so it doesn't take up unnecessary space
This also means you don't need to keep switching between the browser and your apps

Ignoring the AI part (which was the reason why I came up with this idea)

This will be very easy to do in WinUI 3, not sure about UWP though
You'd have to set the current window as a child of another and make it position itself automatically according to parent window size/position/state changes

Would it not be easier to have it act like tab tearing and just have it go from window to content within the other window and back again?

e.g. having some general content area container that handles that could be interesting.

But maybe I'm misunderstanding your scenario. Some pictures or video could help.
