Open the assistant, then press the pin in its header, to the left of the close button.
When docked, the assistant is a column down the right of the screen. The page gets narrower to fit beside it, so it hides nothing on the tab.
You can read your claim lines and answer the assistant at the same time.
Press the pin again. The assistant floats back over the corner of the page, as before.
The assistant stays pinned on this browser until you unpin it.
When you close the assistant, it remembers the pin. The next question opens back into the column.
The pin shows only on a wide screen.
The column takes its space from the page and does not cover it. So the pin shows only where the page still has its full width beside the column. It does not show where it would squeeze what you read.
Widen the window and the pin comes back.
The widen arrows are only for the floating panel. When pinned, the column already has its width. So that control goes away, and does not stay on screen doing nothing.
