For the moments you want to keep.

The idea behind JoyCapsule: a little place for the things that matter to you.

  1. 1

    Keep the moment

    A photo, a thought and a few words. What makes this moment yours?

  2. 2

    Seal it for later

    Choose a future date. In three months, a year or for a special occasion.

  3. 3

    Open the memory

    Meet your past self and the little details you may have already forgotten.

Some moments are yours alone.

JoyCapsule is being built as a private place for personal memories. You decide what matters to you.

  • Private by default, as planned
  • Room for your own happy moments
  • Your pace, without a daily obligation

Even an ordinary day can be worth remembering.

In a study using time capsules, participants underestimated how interesting everyday memories would be months later.

A few more questions?

Some answers about the idea and the planned launch.

Can I use JoyCapsule yet?

JoyCapsule is still in development. The sample capsules on this page show you the idea. You can't sign up or save your own memories here yet.

What is a digital time capsule?

A memory for which you choose a future opening date. Photos and texts for your future self are planned for the first test.

Are my moments public?

JoyCapsule is intended as a private place. At launch, new moments are planned to be visible only to you. Intentional sharing with others is planned for later.

Do I have to capture something every day?

You decide when and what you'd like to capture. The planned launch has no daily obligation and no public leaderboard.
