Sunli is open on the web as an early version. The phone apps are not ready yet.

One small thing a day for the people who matter.

Today’s card

RuthMother

eye appointment at 3

Ruth sees the eye doctor at three.

Ring her after.

Your mother’s appointment on Thursday. The friend who starts a new job on Monday. Sunli keeps things like these, and each morning it puts one in front of you. You decide what each person sees of you.

How it works

Each morning, one person and one small thing.

Most of us are not careless with the people we love. We are busy, and we don’t always know what would help.

The screens in the film are a preview of the design, captured from the prototype. The app is still being built. The voice was made with a computer.

What the film says

You meant to ring your sister today. She lives in Toronto now, and you’re never sure what time it is there.

Everyone has an orbit. The people who matter to you: near, far, gone, or still to come.

Sunli helps you be good to them. It remembers what matters, and gives you one small thing to do today.

Put your people in your orbit. Anyone who matters to you, near or far.

Each person gets a page. Nora likes cardamom tea and long voice notes. She hates the cold. Tell Sunli once, and it remembers.

Hard days go better when people know what helps. Lena wrote it once, in her own words, and chose who reads it.

So when she says nothing’s wrong, Daniel has one small thing he can do today.

Someone far away? See the hours you’re both awake.

Someone gone? Their page stays, with the things they always said.

Talk to the companion. When it isn’t sure, it asks.

By text or by voice. What it keeps about your people, you can see and change.

Sunli. Everyone has an orbit. See how it works — sunli.app

  1. The orbit screen: you in the middle and six people on three rings, Daniel, Ivy, Ruth, Thomas, Clara, and Nora far away in Toronto.

    Put your people in your orbit

    Your wife or husband, your parents, a friend, a colleague. Some live in your house and some are an ocean away. The closest stand nearest to you.

  2. Lena’s Guide, titled “In my own words”, with lines such as “On slow days I don’t want solutions” and who reads each one.

    They write what helps, in their own words

    Anyone can keep a Guide: what helps on a slow day, what not to ask at the door. They choose who reads which line.

  3. Daniel’s Today screen. One card about Lena: she set her signal to “quiet” this morning, a line from her Guide asks for dark chocolate and not much talking, and the small thing is to bring chocolate home and take dinner off her hands.

    Each morning, one small thing

    A card for one person, built from what you know and what they wrote. Ring her after the appointment. Have the kettle on.

A preview of the design, captured from the prototype. The app is still being built.

Everyone has an orbit.

The people who matter to you, drawn as a small sky with you in the middle. Some of them live in your house. Some are an ocean away. One may have died, and some you haven’t met yet. All of them belong.

  • Near

    The people you see every day

    Being near someone doesn’t mean you know what would help today. Sunli gives you one thing, and often it comes from what they wrote themselves.

    For him: “She said nothing’s wrong.”

  • Far

    The people a few time zones away

    Sunli keeps their clock beside yours and tells you a good hour to ring. Your mother doesn’t need the app for any of this.

    Far from family: “Is it too late to ring Mum?”

  • Remembered

    Someone who died

    They stay in your orbit. Their page keeps the things they always said and the dates that matter, and it goes quiet on the days that hurt. Nothing in Sunli ever speaks as them.

    Remembering someone: “Her page stays.”

  • Still to come

    When there is hardly anyone yet

    Start with one name, someone you already know. Sunli suggests one small step a week towards them, and helps you write the first line.

A conversation with the companion. You write that your sister moved to Toronto, and it asks which sister you mean, Nora or Clara.

A preview of the design, captured from the prototype. The app is still being built.

The companion

It says so when it doesn’t know.

You can write to the companion about the people in your life, for help with the next small step. It knows only what you tell it in that conversation. It does not read your people’s pages and does not change them.

It is an AI with a face, so you always know what you are talking to. It doesn’t play a person, it doesn’t diagnose, and it never speaks as someone who has died.

Before your first message, the app asks if your messages may go to OpenAI, which writes the replies. A small review team at Sunli can read conversations, to make the answers better. You can delete any conversation.

You decide what each person in your orbit sees.

These are the rules Sunli is built by. The privacy policy says what is kept, who can read it and how to delete it.

  1. Nothing you write is sold, and there are no adverts. A small team at Sunli can read it, to improve the app and to help you.
  2. The people in your orbit see only what you chose to show them. Every new person starts at “Nothing”.
  3. You can delete any conversation with the companion.
  4. What you tell the companion is never shown to anyone else who uses Sunli.
  5. Nothing on your lock screen says what kind of day you are having.

Works today

Is it too late to ring Mum?

Pick two cities and see the hours when you are both awake, and a good time to ring. It runs in your browser and keeps nothing.

How often should I call my parents?

There is no right number. Four questions help you find a rhythm you can keep and they would like, and one short conversation makes it stick.

Where things stand

Sunli is open on the web as an early version. The iPhone and Android apps are being prepared.

There is no list to join. When there is a way to hear from us, it will be on this page.

The early version works on the web today: Open the web app

One part of it works already, here on the site: When can I ring?
