One deep question a week

A question from Derin

What's an underrated quality I have that you don't think I get enough credit for?

Every question comes from the collection we are writing for the pilot. One like it arrives each week.

How a week works

  1. Step 1: The day you choose

    The question arrives

    Everyone in the group gets the same question on the same day, with a notification that opens it.

  2. Step 2: During the week

    Everyone answers

    In your own time, by text or voice. You see the others' answers once you've given yours, so nobody is swayed.

  3. Step 3: Whenever you like

    You talk it through

    The answers open the week's conversation in your group's private chat, with text and voice notes.

  4. Step 4: When the week ends

    A recap to keep

    A short note of what came up, what you learned about each other, and something to try next.

Made for people far apart

Weekly, not daily

One question a week leaves room for a real answer and a real conversation. A week nobody answered simply closes, so there is never a pile of questions waiting.

Any small group

A couple is a group of two. Bring a parent, your siblings or the friends you grew up with, up to ten people.

Your history stays yours

Every answer, conversation and recap stays in your group's history. Nothing you have written is ever locked behind a payment.

Only your group can read it.

Not us, not Google, not an AI company. Messages are end-to-end encrypted on your phones, with the Signal protocol that Signal and WhatsApp use.

  • Your words are never used to train AI.
  • If your group uses AI recaps, that week's messages go to our AI provider to write the recap, and are then deleted.
  • No ads, and no location tracking.

Derin starts with a four-week pilot for ten pairs: two people who live apart, one question a week, and your honest view of what worked. It's free.

Sign up and we'll email you if there's a place, with how to install the app and invite the other person.

Questions about Derin

What does Derin mean?
Derin is Turkish for deep. Turkish uses it for the sea, for sleep, for thought and for love: derin bir sevgi is a love that goes all the way down. It is also a name parents give a child, wishing them a life with depth. Miles measure how far apart you are; depth measures how close. Derin is for the depth.
Who is the pilot for?
Two people who live apart and want to talk about more than their day: partners, a parent and a grown-up child, siblings, close friends. Each of you needs an iPhone or an Android phone.
Do we both need to sign up?
No, one of you is enough. If there's a place for you, we'll email you with how to install the app and invite the other person.
When does it start, and what does it cost?
Soon, and it's free. Everyone who signs up hears from us before it starts, and only about the pilot.
Can you read our conversations?
No. Messages are end-to-end encrypted, so only the people in your group can read them. The privacy policy lists everything Derin does keep.
When can everyone download it?
After the pilot. Derin is coming to the App Store and Google Play.
