Try it: calls

Calls cost the most

Every minute of a call uses credits, and a video avatar adds more. Plan the demo, show it, and end the call. Do not leave a call running while you talk to the room.

Do this	The viewer should see	Watch out for
Tap the call button in a Space.	The call connecting, then the Spark's avatar, labelled as AI.	The first connect can take 10 to 20 seconds. Say so before you tap.
Say "Let's talk through my week."	A natural back and forth. Interrupt it to show it stops and listens.	Speak one at a time if others are in the room.
Say "Draw me a diagram of this plan."	Share a board? the first time, then a live sketch.	Say yes once; it will not ask again.
Say "Make me a picture of a cosy café, warm light."	The picture appears on the call's Screen view.	Pictures use credits too.
Tap the model pill and switch to Duet.	The call reconnects for a moment, and the conversation carries on.	Keep this short; it is a nice detail, not the main event.
Leave the call screen and open Pulse.	A small call window stays in the corner. Tap it to go back.	None.
Say "Please hang up."	The call ends and offers View summary.	Summaries take a moment and are not guaranteed.
In chat: "Call me in 5 minutes."	"Call scheduled for..." and a card. Five minutes later, the phone rings.	Phones only, with notifications allowed. Up to 3 scheduled calls a day.

Avoid in a demo: the Schedule a call screen (it does not book a real call yet), claiming calls are recorded (they are not), and promising a particular language works on every call model.
