What people use it for

Ten everyday things it does for you.

Everything below happens by voice, with a written summary afterward. Nothing is bought or paid for without your OK.

  • 01

    Replace your voicemail

    Forward the calls you miss to your Bot. Callers get your Chief of Staff instead of a beep. It knows who you are and takes real notes.

  • 02

    Take a call and get the details

    The contractor, the school, the pharmacy. Your Bot asks the follow-up questions and writes down the price, the date, and the options.

  • 03

    Book a table

    Say the place and the time. Your Bot calls the restaurant, works out the slot, and books it under your name.

  • 04

    Order dinner

    Say what you want. Your Bot builds the order. Nothing is charged until you confirm.

  • 05

    Groceries

    Read out a list or a recipe. Your Bot fills the cart. You check out.

  • 06

    Move a meeting, or say you're late

    “Hold four to five with Priya.” “I'm twelve minutes late.” Your Bot updates the calendar and lets the other side know.

  • 07

    Everyday errands

    Dry cleaning, the florist, the pharmacy callback. Say it once. Your Bot handles the call and sends you the note.

  • 08

    Notes on the go

    Walking between meetings, tell your Bot what can wait and what it should draft. It's waiting in your Bot's chat when you sit down.

  • 09

    Travel callbacks

    Airline, hotel, rental car. Your Bot answers the callback, takes the details, and pings you only if there's a decision to make.

  • 10

    Family gets through

    A short list of people you approve reaches you through the line. Everyone else gets a polite assistant.

Related questions

Straight answers.

Can it book restaurants on OpenTable or Resy?

It books restaurants the way that works everywhere: it calls them. It asks for the time, gives your name and a callback number, and confirms the details. OpenTable, Resy, and Tock don't let outside assistants book through their apps, so the phone is the clean path, and it works for any restaurant with a phone number.

Can it replace my voicemail?

Yes. Forward the calls you miss on your mobile to your line. Your carrier has a short code for this, and Settings → Replace voicemail shows it filled in with your number. Callers then reach your assistant instead of a beep. It takes real notes, and the summary is marked “Missed on mobile.”

Can it spend money or commit me to things?

On a call, no. It never gives out a card number or agrees to a charge, so a booking or appointment is the most it commits you to. Your plan's minutes are the only thing the line itself spends, and app orders (dinner, groceries) go through only after you confirm.
