Write a letter, attach photos or a video, set a delivery date — from tomorrow to 50 years from now. Capsule keeps it safe and delivers it exactly when you choose.
50,000+ capsules sealed and waiting to be opened
Create a capsule in minutes, set a future date, and we handle the rest — including reminding the recipient when their moment arrives.
Compose a letter, record a video, or attach photos. Rich text, audio notes, and file attachments all supported — up to 2GB per capsule.
Choose exactly when your capsule is delivered — a specific birthday, a milestone anniversary, or any date up to 50 years from now. You can also set conditions like "open only if I haven't logged in for 1 year."
Once sealed, your capsule is encrypted and stored securely. On delivery day, the recipient gets an email with a private link. No account required to open it.
From first-time parents to wedding photographers, Capsule fits naturally into the most meaningful moments in life.
Write a letter to your newborn to be opened on their 18th birthday, their wedding day, or their first day of college.
Deliver the final wedding video on the couple's first anniversary. Automatically, with a personalised message — no follow-up email needed.
Send a heartfelt message from the CEO on each employee's 1, 3, and 5-year anniversaries. Bulk scheduling for your whole team.
Write a letter to your graduating class to be delivered on their 10-year reunion. Students can contribute to a shared class capsule.
Couples write private messages on their wedding day to be opened on milestone anniversaries — 1, 5, 10, 25 years.
Write to yourself 1, 5, or 10 years from now. Reflect on goals, fears, and dreams — then receive a reminder from your past self.
Every detail of Capsule is designed around one guarantee: your message reaches the right person, at the right moment, exactly as you intended.
We're not a startup that might disappear. Capsule stores every message across three geographically separated data centres with AES-256 encryption at rest.
Paid plans include our Continuity Pledge — if Capsule ever shuts down, we transfer all capsules to a designated legacy partner before closing.
Attach photos, videos, voice notes, PDFs, and files — up to 2GB per capsule. We preserve original quality for the lifetime of the capsule.
Invite friends, family, or colleagues to each contribute a message to a shared capsule — perfect for class projects, retirement gifts, or group tributes.
Set conditions beyond a date: "deliver only if I haven't logged in for 12 months", or "let my executor unlock this at any time." Useful for estate planning.
Recipients never need to create an account. They get a private link by email, open their capsule in a browser, and that's it. Simple, beautiful, zero friction.
"I got a message from my dad on my 30th birthday. He'd written it when I was 5. Reading his voice — the exact way he put words together — destroyed me in the best way."
"I started including a Capsule delivery on every wedding package. Couples lose it when they get their video on their first anniversary with a personal note I wrote on the day. It's my best upsell."
"We set up a capsule for every new hire — from the CEO, delivered on their 1st work anniversary. Our 1-year retention went from 68% to 81% in 18 months. Small thing, enormous impact."
Your first capsule is always free. Paid plans unlock unlimited storage, longer delivery windows, and team tools.
