Sensei runs on Meta Ray-Ban Display glasses as a web app. The glasses show what needs you, one card at a time, and take your answer out loud. The work itself runs in the cloud, so the glasses only show the result and send your yes.

## What you need

- Meta Ray-Ban Display glasses, paired with the Meta AI app on your phone.
- A Sensei account. [Sign up](https://app.kosuke.ai) on a computer first if you have none.
- Your iPhone or a computer nearby, to approve the sign-in.

## Open Sensei on your glasses

1. On your glasses, open the browser.
2. Go to `app.kosuke.ai/glasses`.

## Sign in

The glasses have no keyboard, so they sign in with a code:

1. The glasses show a short code, a web address and a QR code.
2. On your iPhone or computer, open the address or scan the QR code, and sign in to Sensei if it asks.
3. Check that the code matches the one on the glasses, then approve.

The glasses sign in on their own once you approve. If the code expires, choose **New code** on the glasses and start again.

## Answer Sensei

When Sensei needs you, the card shows on the glasses: what it did, what it asks and its button, such as **Merge** or **Send**. Say your answer, or use the button. A card that needs more than one answer opens on your iPhone or computer instead.
