Attacks often look like ordinary work

Hidden instructions can sit in what it reads: an email, a page, a file. A send still needs your OK.

Sends and payments, asked first

Even the small tools it writes for a site ask first: every message it would send and every bill it would pay waits for your OK.

Careful, without slowing you down

Asking about everything is easy. It asks when it matters: before it sends, and before it pays.

Early access

Pages can't give it orders

Hidden text in an email or a page doesn't send anything. Only you do.

Normal work keeps going

Reading, drafting and filling things in go ahead. Only sends and payments stop for you.

Built not to type your secrets

Passwords and card numbers stay yours to type.

Only looks while you ask

It sees your screen only while the pill is open.

Give it a job, it asks first

Read what it keeps, what it sees, and the switches for both.

Questions and jobs

Do anything

Ask it a question or hand it a job, in any app.

Doing jobs for you is in early access on Mac. Asking works on Mac, Windows and Linux.
