Some things shouldn't be read right away. Some feelings need distance before they make sense. Some words are meant for a version of you that doesn't exist yet — and won't exist for months, maybe years.
That's the idea behind a time capsule journal. You write something today, seal it, and set a date. When that date arrives, the capsule opens. Your own words, waiting. Written by someone you no longer are, to someone you hadn't yet become.
When you write a regular journal entry, you're recording the present for the past. When you write a time capsule, you're reaching forward. It's a different kind of writing — more intentional, more vulnerable, because you know the person reading it will have lived through things you can't predict yet.
A time capsule is a letter that crosses time in one direction only. You can send it, but you can't take it back.
People use time capsules for all kinds of moments. Before a big life change — a move, a new job, a breakup. On New Year's, when you're full of hope. On an ordinary Tuesday, when nothing special is happening and you just want your future self to remember what ordinary felt like.
In Yearbound, creating a time capsule takes about a minute. You write your message, choose a date, and seal it. The capsule disappears from view until the date arrives. No peeking, no editing, no deleting. When the day comes, you get a quiet notification: something you wrote in the past has arrived.
Unlike physical time capsules buried in backyards, a digital time capsule inside an encrypted journal is protected. End-to-end AES-256 encryption means no one reads it before you do — not even us.
Write to yourself one year from now. Tell future-you what you're worried about today. What you're hoping for. What you believe. A year later, reading those words, you'll see how much has changed — and how much was already in motion without you knowing.
Or write to yourself for tomorrow morning. Just three lines about today. Sometimes the shortest distance a message can travel — one single night — is enough to surprise you.
