# Sage

A Mac assistant in the notch.

Hold a key, say what you want, let go. Sage works out what you meant, does the steps one after another, and ticks each one on the island as it finishes.

## Hold, say, watch.

Each one as it looks on the island.

### Hold to talk

Hold right Option and talk. Your words show up live on the island, in English, Italian or Chinese.

### Steps you can watch

Say "I want to join the standup" and it finds the event, opens the call and turns your mic and camera off, ticking each step.

### Asks first

A step that changes something shows its question and a line that fills over five seconds. A step others would see, that moves money or can't be undone, waits for your yes.

### Hands it back

A Pay or Send button is never pressed for you. Sage outlines it and hands it back: "Stopped at Pay. It's yours to press."

## Nine buttons it never presses

It outlines them and hands them back.

- Pay
- Send
- Buy
- Order
- Delete
- Sign
- Push
- Publish
- Share
