Birthday capsules

A birthday time capsule instead of another card

Everyone who loves them writes a note now. It stays sealed and comes back on a birthday down the line.

Notes for the birthday

  1. Writing closesAug 28
  2. It opensAugust 14, 2027

Writing closes a couple of weeks out, and the capsule opens a year later.

How it works

  1. 1

    Start the capsule

    Name it, pick the day it opens, and share the link in the group chat.

  2. 2

    Everyone adds a note

    A memory, a photo, a wish. Nobody sees anyone else's words.

  3. 3

    Open it on the day

    Every note lands at once β€” far better than a card nobody kept.

What guests see

One page with a writing box and a few gentle prompts, so nobody sits there wondering what to say:

  • A memory of you I keep coming back to…
  • What you were like this year…
  • Something I hope for you…

Notes are sealed the moment they're written. Nobody can read them early β€” not even the person who started the capsule. How we handle your words.
