Letta lets you write letters to the people you love — sealed, private, and delivered at the exact moment you choose. For your passing. For their 18th birthday. For the day they need to hear from you most.
You don't have to be old or ill. You just have to love someone.

What a letter looks like
TO: Emma
OCCASION: 18th Birthday
To my daughter Emma, on your 18th birthday.
I wrote this when you were six. You had just learned to read and you were so proud of yourself — you read every sign we passed on the way to school, out loud, without stopping.
I want you to know that I have been proud of you every single day since. Not because of what you achieve — but because of who you are. The way you notice when someone is sad. The way you laugh. The way you love the people in your life without holding back.
Whatever happens, whatever life looks like when you read this — you were loved completely. You still are.
All my love, always.
This is a fictional example. Your letters are private — only your loved one will ever read them.
What Letta does
Write to your children, your partner, your best friend. The things you mean to say but never quite find the moment for. Write them now, while you have the chance.
Check in regularly to keep your letters sealed. If you stop, Letta escalates gently — first a reminder, then your emergency contacts — before anything is delivered.
Every letter is encrypted and sealed. No one can read them — not even us — until the exact moment you intended. Your words stay yours until they need to be theirs.
Each letter goes to one person. When the time comes, they receive a private, secure link — just for them — with everything you wrote, exactly as you intended.
How it works
Write to anyone you love. Set an occasion — on your passing, a future milestone birthday — and say as much or as little as you want. There is no word limit.
Add the people you're writing to. Letta will deliver each letter to the right person at the right time — privately and securely.
Choose how often you check in. Miss your deadline and Letta escalates gently — first a reminder, then your emergency contacts, then delivery.
Your letters are sealed and waiting. Check in whenever you want to keep them from delivering. When the time comes, they'll be there.
How delivery works
Letta doesn't just store your letters — it watches over them and delivers them at exactly the right moment, with multiple safeguards to make sure nothing is sent by mistake.
Your letter is encrypted the moment you write it. Nobody can read it — not your loved ones, not us — until the exact moment you choose. It sits sealed in your vault, waiting.
AES-256 encryption · Zero-knowledge storage
You check in regularly — weekly, monthly, however you prefer. As long as you check in, nothing is ever sent. You stay in complete control for as long as you're here.
You set the check-in interval · Reminders sent before deadline
If you miss a check-in, Letta doesn't immediately deliver. It sends you a reminder first. Then a second reminder. Then it contacts your nominated emergency contacts to verify. Only after all steps are exhausted does delivery begin.
Multiple escalation steps · Emergency contact verification
When the time comes, each person receives a private, secure email with a link that belongs only to them. They open it and find your letter — exactly as you wrote it, exactly as you intended.
One link per recipient · No account needed to read
End-to-end encrypted
Letters are encrypted before they leave your device. We cannot read them.
No surprise deliveries
Multiple escalation steps before anything is sent. You stay in control.
Delivered at the right time
Set the exact occasion. Letta waits — for years if needed — and delivers precisely.
