A digital time capsule, built of letters

How it works

Three steps, and no magic beyond what time does on its own:

• Write the letter like any other: stationery, seal, your own pace.
• Choose the time-capsule ritual and a delivery date — a specific day, not “someday”.
• The letter waits as an encrypted envelope. The server does not receive its readable content.

What people write into a capsule

A time capsule needs no grand occasion, but a few moments suit it especially well:

• New Year’s Eve or a birthday — a letter to reckon with, one year out.
• The eve of a big change: a move, a new job, a wedding.
• A letter to your future self — the honest kind, since there is nobody to pose for.
• An anniversary letter — to yourself, or to the two of you.

Why it beats memory

Memory smooths things over. Years later we keep the conclusions and lose the ordinary days — and the ordinary days are what is worth rereading. A letter freezes the day as it was: the prices, the sounds, the worries that felt enormous.

Unlike a notes app, a scheduled letter is written for a specific future moment. You can still review, edit, reschedule, or cancel it before delivery; the recipient cannot receive or open it until the chosen date.
