The Ai orb

The orb is the single way into Ai; there is exactly one on every screen and it is always in the same spot. The gradient (cobalt → turquoise → burgundy) carries the burgundy Q icon; when idle it breathes slowly.

1. 1Tap: the chat opens in a balloon window floating over the screen you are on; you don't go to a separate page. On Home it is the library assistant ("Your library · 12 documents"), in the reader the document assistant ("Sees this document"). A document that is being read keeps reading underneath.
2. 2Press and hold: voice mode starts; the assistant listens to you, reads its answer aloud and works hands-free.
3. 3Minimise: tap the empty space around the balloon, press back or (on the web) press the minimise button. When Ai opens a screen or a document, the balloon shrinks back into the orb by itself. The chat isn't closed: a streaming answer carries on, and tapping the orb again opens it where it left off (on the web a green dot on the orb shows the chat is open).

The orb knows what you are looking at: "summarise this" means the library on Home, and the open document, or even the current page, in the reader. In a chat opened from Settings or Tools, a line such as "Now seeing: Tools" appears under the title; when you leave the chat, that screen opens again. It doesn't go into topics outside (news, general knowledge).
