A message to one person
A letter and a recording for a child, a partner, a friend. Opened on a birthday, a graduation, or a date you name.
Preserve · Beta
A private capsule for the people who come after you
Letters, recordings, photographs and documents, sealed for the people you name and opened when you choose. Add to it over the years. Invite family to add too.
Preserve is in beta
Preserve is in beta. Capsules you create now are private, exportable and yours to delete. We are building the release process carefully and will not promise a delivery date we cannot keep. Your own exports are always the surest copy. How we think about continuity
How it works
Five steps, taken at your own pace
Create a capsule
Personal, or shared with family. Give it a name and a purpose.
Add what matters
Letters, voice notes, video, photographs, scans. Note the context behind each item so it is understood later.
Invite contributors
Family and trusted people can add their own items. You decide who may see what.
Name the recipients
One person or several, with a legacy contact who can help if you no longer can.
Choose the opening
A date, a milestone, or a decision left to your legacy contact. Change it any time.
Plain language
What a capsule is, and what it is not
What we do
- Store capsule content privately, off any public address, with access checked on every request.
- Keep an activity log you can read, so you know who added, changed or viewed what.
- Let you export everything as a plain archive at any time, and delete it when you decide.
- Keep administrators out of capsule content by default. Any access is a deliberate, logged act.
- Publish a continuity plan and keep it current.
What we do not promise
- That any online service, including this one, will exist unchanged in fifty years.
- That an email address given today will still reach someone in decades. We ask for several ways to reach recipients and check in over time.
- Automatic release during the beta. Release is handled carefully by people until the safeguards are proven.
- That a capsule replaces your own copies. Keep your export somewhere you trust.
