A time capsule is a letter to your future self. You write it now, seal it, and slowbloom keeps it locked — even from you — until the day it's meant to be opened. It's a quiet way to send a thought forward in time.
Plant a seed
Choose Plant a seed, write your letter (words and images, just like a petal), and pick which plant it will grow as. Each plant takes a different time to bloom, and that choice sets the open date:
- Daisy — 2 months
- Tulip — 6 months
- Rose — 1 year
- Peony — 3 years
- Cherry blossom — 10 years
Watch it grow
A planted capsule appears in your garden as a little plant, working its way up through its growth stages with a gentle countdown to the day it opens. When the day arrives it blooms, and we let you know by email and push notification so you don't miss it.
Sealed until it blooms
A capsule is end-to-end encrypted from the moment you seal it, the same as everything else in slowbloom. The server only ever holds ciphertext, and the contents stay sealed until the open date — so even you can't peek early. When it blooms, it opens with your letter and any images you tucked inside.
Planting a long capsule, like a peony or cherry blossom, asks for a gentle confirmation first — opening years away is a real promise to your future self.
