Most chosen edition

The one most people start with. $19, no subscription, sealed until the day arrives. Best for anniversaries, birthdays, milestones, and any moment worth saying something today and having it land at the right time.

The pain we built it for

You have something to say today. But the day it should land is another day.

Texting it now feels too small. Saving it in your notes app feels like it will get lost.

And waiting weeks, months, years to write it feels worse. By then you might have softened it, or forgotten the feeling, or not be around to write it at all.

·

The Capsule is for that gap. Write the truth now, while it is fresh. Let it open on the day it actually means something.

Do any of these belong to you?

Moments that deserve a specific day.

These are the four pains we hear most often. If one of these is you right now, The Capsule was built for it.

Anniversaries that mean it

The anniversary you want to mark. Not with a card from the gas station.

You know the date is coming. You also know that on the morning of, you will be tired, distracted, late for something. The thing you actually want to say will not get said. It will be a text. It will not land the way it was supposed to.

Write it tonight, while you can feel it. Let it open on the morning. Same words, right moment.

NOW · AGE 3 fifteen quiet years 18TH BIRTHDAY
For a child you will not be the same age as

The letter for your kid on their 18th birthday. Written now, while they are three.

Tonight you watched them fall asleep and felt the kind of love that does not have anywhere to go. By the time they are old enough to understand it, you will be a different person, with smaller words. The version of you who is feeling this needs to be the one who writes the letter.

Capture it tonight. Set the date for the morning of their 18th. The right words from the right version of you.

For the morning of

The letter on the morning of your wedding. Or the morning after she says yes.

You will be wrecked with feeling that day. You will not be able to write anything coherent. But what you wanted to say to them has been in your chest for months. The right time to write it is tonight, while you are quiet. The right time for them to read it is then.

It will be waiting in their inbox at the hour you choose. Read while they are putting their shoes on. Or after the vows.

YOU TONIGHT YOU AT 40
To your future self

The letter to who you will be. Sealed by who you are tonight.

You promised yourself something this year. You changed somehow. You want to remember exactly how you felt. Or you are about to make a hard call and you want the future you, the one who knows how it turned out, to read what you were thinking when you decided.

Choose a date. One year. Five years. The morning you turn forty. The first day you retire. The letter waits, exactly as you wrote it.

How The Capsule works

Write today. Open on the day.

You write the letter, you design the card it lives in, you choose the date and hour. We seal everything. We do not look.

The encryption happens on your device, before your words leave it. Even we cannot read it. We hold the sealed version safely until the day you chose. On that morning, the recipient gets the email, the link, the countdown, and finally the letter you wrote on the day you wrote it.

It feels like the present. It is, technically, a small kind of time travel.

What the recipient sees

A sealed envelope with a countdown.

From the day you send it, until the day it opens.

When the link arrives in their inbox, they can already see the card you designed. The wax seal. The monogram. The occasion. Just not the letter.

A live countdown ticks until the moment you chose. Nothing reveals early. Then on that morning, at the hour you set, the seal opens and they read what you wanted them to read, at exactly the right time.

The Capsule promise

What you actually get, plainly
Encrypted on your device. Your words never reach us in the clear.
Sealed until the moment you chose. Day and hour, your timezone.
Cannot open early. Not even by us. The server itself enforces the date.
Card you design. Colors, monogram, occasion line, wax seal, all yours.
$19, one time. No subscription. No renewal.
Sealed even from us

The letter is private, even from us.

Most "schedule this email for later" tools store your message in plain text on their server. Anyone with access could open it. Anyone who bought the company in five years could open it. So could we.

The Capsule is not that. Your letter is encrypted on your device before it leaves you. We hold a sealed version we cannot read. The server is configured so that even if someone tries to open it early, including us, it returns nothing. The date is the key.

  • Up to 1,500 characters of letter. Enough to say it properly, short enough to mean it.
  • Schedule decades out if you want. The longest current Capsule opens in 2046.
  • If you lose the link, we can reissue it from your email. The letter itself stays sealed.
From tonight to the day

How a Capsule is made.

STEP 01

Write the letter

Encrypted on your device before anything leaves. Up to 1,500 characters.

STEP 02

Design the card

Theme, monogram, occasion, wax seal. The thing they see when the link opens.

STEP 03

Pick the moment

The exact day and hour, in your timezone. Tomorrow, or twenty years from now.

STEP 04

It arrives, exactly then

On the morning, the email lands. The seal opens. They read what you wrote tonight.

"Some things deserve to land on the right day. Not the day you happened to think of them. Not the day your phone reminded you. The day they were meant to be heard."
