Now Available Mac app and iPhone preview

Zero is a personal assistant with a small team of helpers called Zips. Give Zero a task, and the right Zip gets it done and comes back with the finished work.

iPhone preview through TestFlight. Mac app, signed by Apple.

Demo: you ask Zero to email Jordan about the lease. Zero hands the job to a Zip called Home, which writes the email and shows you a card with a Send button. After you tap Send, Home confirms the email went out.

Free to Run and Open Source

Run Zero on your own Mac or home computer with the ChatGPT or Claude plan you already have, and read every line of its code. Hosted plans, for people who would rather not run anything, open later.

Message Zero Like a Teammate

Ask in plain words, the way you would ask a friend who is good with details. Zero keeps track of what every Zip is doing, so you only ever talk to one place.

  • Remembers what you tell it. Zero keeps the details you mention and brings them up when they matter.
  • Answers like a teammate. Replies are a few sentences, with the full details one tap away.
  • Knows who is writing. Each Zip has its own picture and its own sound in your notifications.

Work With Many Zips at Once

You can ask for several things at once. Each Zip takes its own job, and they all work at the same time.

Each Zip Has Its Own Computer

Zips sign in to websites and use them on their own computers and browsers, so your phone stays yours. With your okay, they can work on your Mac too.

Zero Asks Short Questions

When something needs a decision, Zero asks one short question with answers you can tap.

Zips Keep Your Routines

Set up a routine once, like a look at the week ahead every Monday, and the Zip runs it on schedule.

Zero Reads Your Gmail and Calendar

Sign in with Google, and your Zips can see what lands in your inbox and what is on your schedule.

Give Each Zip a Job

Keeps track of what you owe. Bills reads bill emails in your Gmail, tells you what is due and when, and asks before it pays anything.

You can make a Zip for any job you want to hand off.

Who Decides What Zips Do?

You decide, and Zips do the work.

Nothing Goes Out Until You Allow It

Before a Zip sends a message, spends money or deletes something, it shows you a card with the details and waits for your tap.

Sensitive Sites Always Ask

When a Zip wants to sign in to a site that involves money, health or account settings, it asks you every time.

You Can Watch or Take Over

Open any Zip’s computer to see what it is doing, and take over whenever you want.

Where Do You Use Zero?

Zero is on your iPhone and your Mac. Type a message, say it out loud, or call Zero and talk it through.
