Ask Sontara.

We used to call them agents. A Sontara is a partner that helps you become who you’re trying to be.

Tell it what you want, in your own words. It learns your life, does the work, and asks before anything big. By your seventh message, something you’ve been putting off for months is done.

ChatGPT is brilliant, and it meets you for the first time every single morning.

Your Sontara has been with you for months. It knows the contractor thread, the trip you planned in March, how you sign your emails. That’s the difference between a chat and a partner.

Your seventh message

What it looks like when the thing finally gets done.

By the fourth message you start seeing what’s possible. By the seventh, something that would have taken months is done. Three people we built this for — the ones from the Seven Messages films.

Maya, 34 · nurse, nights, two kids

“I've been meaning to finish my degree for four years.”

Message 7: The application is in — and the semester fits around her shifts.

Darnell, 41 · laid off, starting over

“I want to start a home-inspection business but I don't know the first step.”

Message 7: The license process is started, and five neighbors know his name.

Rosa, 58 · runs the family restaurant

“I haven't had an evening to myself in months.”

Message 7: An evening off — and the invoices didn't pile up while she took it.

On it.

How it works

Three steps. Done.

  1. 1

    Sign up

    Email, Google, or Apple. Free forever, no card.

  2. 2

    Give it a name

    It gets a private place of its own, and starts by getting to know you.

  3. 3

    Say what you're after

    In your own words. It learns your life, does the work, and asks before anything big.

Just tell it. It does the thing.

You don’t have to learn how to talk to it. It isn’t about the perfect prompt — it’s about what it knows about you. The more it knows, the more precise it gets, and it remembers, so you only tell it once. How to talk to your Sontara →

Meanwhile.

Set it. Let it run.

Run it on a schedule

Every Sun · 7:00pm

Every Sunday night, lay out the week around my shifts and the kids' schedules, and flag anything that collides.

A day with your Sontara

You woke up to it already done.

It handled the routine on its own — and stopped to ask twice. Anything it can’t take back, it checks with you first.

  1. 6:41am

    Overnight email triaged. Three need you, forty-one didn't.

  2. 8:15am

    Moved your 3pm to Thursday. The other assistant already confirmed.

  3. 11:02am

    Your contractor answered about the deck. Reply drafted, waiting on your yes.

  4. 2:30pm

    Tuition-assistance form filled in from what it already knew about you. Waiting on your yes.

  5. 5:58pm

    March flights dropped $180. Flagged, not booked — you said to ask first.

  6. 11:20pm

    Tomorrow's brief is on your desk. Goodnight.

Sontara made it incredibly easy for me, as a non-technical person, to get real help organizing my life, managing family tasks, and even thinking through business strategy in real time — without needing to know how to code.

Why it’s called Sontara · from Cornelius and Willy

Named for the two people
who make us better.

Sontara is Sonia and Tara — Willy’s fiancée, and Cornelius’s wife. Son + Tara. They’re the reason we’re better than we’d be on our own: someone who knows you completely, believes in the version of you that you’re still becoming, and won’t let you settle for less. We wanted to build that for everyone who doesn’t have it.

Then one day we noticed something we hadn’t planned. Where the n meets the t in sontara, the letters form a π — the symbol for something with no end, that you can keep discovering forever. It was already in the name. So we made it the face of what we’re building: a partner whose understanding of you never stops growing, and a version of you that never stops either.

Most people would love this kind of help and never get past the learning curve. That’s who this is for.

Cornelius & Willy

P.S. Look at the logo. It was there the whole time.

A small open-plan office: a woman on the phone taking notes, a man working a spreadsheet, a colleague laughing behind him, and on the desk beside them the plush pi mascot writing in a spiral notepad while the muppet pi mascot reaches for a sticky note on a monitor

Everyone gets one.
