The voice assistant for your Mac
Double-tap Control and say what you need. Katie compares hotels, finds flights and sums up reports while you get on with your day, and drafts your messages. Nothing goes out until you approve it.
Early beta (v0.0.1) · macOS 14 Sonoma or later
Made for people who would rather just ask
Comparing hotels means tab after tab: prices per night, ratings, maps, which ones are free on your dates. With Katie you say it in one sentence, and the shortlist comes back with its sources.

How Katie works
01 · Talk like you talk
Ramble all you like.
Say umm, pause, change your mind. Katie acts on the last thing you said.
02 · Katie does the legwork
Katie does the legwork.
It reads public hotel pages, compares price per night, rating and location, and keeps a link to every page it used. It never signs in, books or pays.
03 · You approve
Nothing goes out without you.
Katie writes the email and shows you the exact draft. Only your click on Approve sends it, once, in the app or on the web. Never by voice. Email is rolling out to beta accounts.
04 · On your Mac
Double-tap Control. Walk away.
Katie lives on your Mac. Research keeps going after you close it, and a notification, or an email, tells you when the result is ready.
Katie's face on your Mac Next beta
While you talk, Buddy sits in the corner of your screen. One look tells you what Katie is doing.
Under Buddy: mute, and how long you've been talking. Double-tap Control again to finish.
What Katie does
Not a chatbot. An assistant that gets it done.

Hotels and flights, compared.
Say where and when. Katie compares up to 10 hotels by price per night, rating and location, or finds up to 10 flights with times, stops and prices. Every result links to the pages it came from.

Long reads, summed up.
Ask for a public report or article. Katie finds it, sums it up and pulls out the key points, with a link to the original so you can read the rest.

Hand it off. Get on with your day.
Research takes a little while, so it runs in the background and keeps going after you close Katie. A Mac notification tells you when a result is ready, or an email if the app isn't open.

Email, only when you approve.
Katie writes the email and shows you the exact draft: from, to, subject and every word. Approve it and it's sent once, from your Gmail. Katie can only send: it never reads your mail. Email is rolling out to beta accounts.

WhatsApp, ready to send.
Say who and what. Katie writes the message, you approve it, and WhatsApp opens with it filled in. You press Send: Katie never sends it for you.
You're always
in control.
No surprise emails or messages. Every draft waits on a card that shows exactly what will go out and to whom, and only your click on Approve, in the app or on the web, lets it go. Katie can't approve anything by voice, and that rule is in its code, so the AI can't skip it.
Research reads public web pages only: Katie never signs in, books, buys or pays. With Gmail, Katie can send the emails you approve and nothing else. It never reads your mail.
