Try it: chat and memory

Type or say	The viewer should see	Watch out for
"Saturday is packed: farmers market at 9, pick up coffee beans, gym after. Make me a checklist."	A checklist card with tickable items.	Nothing costly. A good opener.
Hold the mic: "Remind me what we decided about the launch date."	The voice note appears at once with a 👀 reaction, then a reply that uses earlier context.	On a new account there is no earlier context, and the Spark will say so.
Attach a PDF: "Summarise this and list three decisions I need to make."	A short summary and a list, drawn from the document.	Use a harmless sample document.
"Remember that my sister's birthday is on the 12th." Later: "When is my sister's birthday?"	The later answer uses what you told it.	Memory builds up gradually; a fact from seconds ago may be answered from the conversation itself. That is fine.
Open the Spark's profile, tap Memory.	The Brain, with items labelled by where they came from.	Only on an account with some history. Never on a personal account.
Send two messages quickly.	The second waits in Up next. Tap stop on a reply: it stops at once.	None.
Open the Spark's profile, tap Personality, pick Witty, and add "Call me Captain." Back in chat: "Quick one: what should you call me?"	The sample reply re-speaks as you switch voices; the Spark answers "Captain."	Switch back to the usual voice afterwards.
Tap the model chip, then More control.	Thinking levels from Auto to Max.	Higher levels are slower and cost more.

Avoid in a demo: searching inside a chat (not built yet), topics (not shown in the app yet), and dragging a file onto the chat (not supported).
