Sealed means sealed
Nobody reads a sealed note before it opens. Not the other guests, not you, and not even the person who wrote it. You see how many are waiting; that is all there is to see.
The part that arrives later
A wooden box in a garage depends on somebody remembering it exists. This doesn't. Your guests fill it in while they RSVP, it seals, and on the day it opens we email it to you to pass on — a first anniversary, a child's eighteenth, ten years after a graduation party.

One for each occasion
Guests write to the person that baby will become, and the letters open on their 18th birthday — or a date you pick. Nobody writes "congrats" to someone who isn't here yet, which is exactly why the letters come out extraordinary.
At a bridal shower, guests write to the couple, and the letters open a year after the wedding date you enter. Paper is the traditional first-anniversary gift.
At a graduation, guests call where the grad will be living and what they'll be doing; at a retirement, how the first year will go. When it opens, the guest of honor says what actually happened and everybody finds out who called it.
Setting one up
Every capsule already shows the day it will open, worked out from something you've told us — the party date, the wedding date you entered for the shower, the baby's real birth date once it exists. Your job is to read it and agree. A date that has already gone is refused rather than opening the second you press the button.
Written on the day it all happened. Opened on the day it means the most.
What we can and can't promise
Nobody reads a sealed note before it opens. Not the other guests, not you, and not even the person who wrote it. You see how many are waiting; that is all there is to see.
The capsule is complete the moment your guests write it. It doesn't need the invitation, the event page, or you logging in again — and the private link inside never changes.
The reveal is emailed to the account that owns the event, and the link can be forwarded — so you pass the graduate their own capsule when the day comes.
We keep the recipient's email that whole time, and an email address can stop working without us knowing. For an eighteen-year horizon, use an address you expect to keep.
Opened years from now
Letters and predictions your guests seal at the party, arriving on the anniversary, the birthday or the decade you choose.

Common questions
To the email address on the account that owns the event, and the link inside can be forwarded — it never changes. The one exception: when the baby arrives and you enter the real stats, the guests with the closest predictions are emailed that they won.
No. Sealed notes are held server-side and there is no screen — host, guest or author — that shows one before the day it opens.
The graduation and retirement capsules ask structured questions — which city, what job, married, kids. When it opens, the guest of honor types what actually happened and every guess is scored against it. No login required a decade later; the link is the key.
It still opens, and says so plainly, rather than arriving as a confusing empty page.
Cancel a scheduled capsule at any time and it stops immediately. Delete the event and it goes with it — nothing is delivered afterwards.
Four occasions, each with the capsule that fits: Letters to the baby, A letter for year one at a bridal shower, The 10-year capsule at a graduation and The one-year capsule at a retirement. Birthdays don't have a capsule.
