A time capsule made of people, not objects.

It isn't storage

Anything can hold files. A time capsule is defined by two things a folder doesn't have: an intended recipient, and a date it opens.

Every SENTiment has both. That's what turns a collection of recordings into something that arrives.

To be opened in 2040.

What goes in one

• Letters to a child, dated and set to open at different ages.
• A voice recording from a grandparent, kept for a grandchild.
• A video of the house, the street, the ordinary afternoon.
• A letter to your future self, opening on a date you chose.
• A note about this year that nobody will otherwise remember.

Building a family capsule

Start with one letter per person per year. Set them to open at eighteen, or on a specific birthday, or ten years out.

A decade later, a family has something genuinely rare: a sequence of honest letters, in the right voices, arriving at the right ages.

Paper, when it should be paper

Digital delivery keeps the recordings and the dates. Seal & Send turns any written letter into physical mail, so part of the capsule ends up in a drawer where somebody can find it by accident.
