You went blank. The other person is waiting, and the thread of the conversation is slipping. The window already has the answer. You read it, you say it, the call keeps moving.
A window on your side of the call
Sayli floats on top of your call as a small pill. Nothing about it reaches the room: no participant joins and no banner appears. Sayli also asks your operating system to keep the window out of a screen capture you start, and how completely that works depends on the platform, stated exactly at What each platform delivers.
The pill is deliberately quiet. A small orb moves with the room, which is how you know Sayli is hearing you, and that is the whole status display: no word while it is steadily listening, and no elapsed clock, because your call app already shows one. A word appears only when something changes, like reconnecting.
Everything else on it is a control: Help me, Scan, stop, and one chevron that opens the pane and folds it back.
The pill during a call. The orb is the signal that Sayli is hearing the room.
Open the chevron and the pane appears under it, holding the ask input, the Help me chip, and pickers for the Persona, the language, and whether a screen share can see Sayli.
How it answers
Press ⌥+↵ from wherever you are, even with Sayli in the background, and it opens and answers. Inside the window, type a question and press ⌘+↵. Answers stream as they are written, so you read while Sayli is still writing rather than waiting for a finished paragraph.
Every answer draws on what fits the question. Connected tools are not among them: they are switched off for the whole recording, deliberately, because a tool round trip costs more time than a live answer can afford. They run after the call, on the brief and on post-call questions.
That mix is why the answer fits the call you are on, not a generic version of it.
Help me, and Scan
Two one-tap moves, and neither fires on its own. The one thing Sayli does unasked is quiet: when the other side asks you a question, it raises a hand, with no sound, and lets it go after 15 seconds. You can turn that off in Settings, under Audio.
Help me is the primary move and the one worth learning. It sits on the pill itself so it is reachable without opening anything.
Move it, fold it
Drag the window anywhere on screen. Put it where your eyes already are, off to the side, near the speaker tile, wherever fits the call. ⌘+↑ and the other arrows nudge it, and holding one keeps it sliding.
The chevron folds the pane back into the pill, which is the tuck-away gesture. There is no full hide during a call, deliberately: a copilot you cannot see is one you forget you are running. ⌘+\ shows and hides Sayli outside a call.
⌘+↵ sends what you typed. Press it with the box empty and it fires Help me instead, so the same chord always gets you an answer.
