A reverse family journal. Instead of waiting for your kids to ask, write to them now — from the trenches of raising them. Bath-time disasters, hard lessons, proud moments. Sealed away in their mailbox for someday.

See it
Write a small thing tonight. It lands in your child's private mailbox — some letters they read this weekend, others stay sealed until a birthday years from now.
A letter takes two minutes. Use the prompt or write freeform.
Each letter waits in your child's mailbox. Some open today. Others stay sealed for years.
Try it
Four small beats. Two minutes tonight, fourteen years of waiting, one moment they read it. Tap Next — or just watch.
You climbed onto the kitchen counter
and announced you were in charge
of the toast now.
I almost said no. Then I watched you
very seriously butter four pieces…
Tonight, you write a small thing.
Two minutes between bath and bedtime. A prompt makes it easy.
How it works
01
One profile per child. Even your unborn ones — start a letter for the baby you haven't met yet.
02
Two minutes or two hours. Use a prompt or write freeform. Tag the moment, attach a photo, send it.
03
Each letter waits in their personal mailbox. Some open today. Others stay sealed until their 18th birthday.
Stuck for words?
Daily prompts adapt to your child's age — from a newborn's sleeping face to a teenager's music taste. Funny, proud, hard, deep. Whatever the day asked of you.
"What's the funniest thing Theo said this week?"
"Write about a moment you saw Olivia show kindness."
"What's something you wish your parents had told you at this age?"
"It's their birthday — write a letter for the same day, years from now."
"I started one for my newborn at 2am during a feed. Now I can't stop. It's the only journal I've ever kept."
"I locked one for my son's 18th birthday. Knowing it's there waiting for him changed how I parent today."
"We invited my husband. Now both of us write. The kids are going to inherit a story told from both sides."

Built to outlast us
You're trusting us with the most important thing you'll ever write. Here's exactly how we hold it — and what happens if we ever can't.
Every letter is encrypted in our database. Your words are never used to train AI, never sold, never scanned for ads.
Hosted on infrastructure with daily backups across multiple regions. Your archive doesn't live on one hard drive in one room.
We're the caretakers, not the owners. You can delete everything in two clicks — or hand it to your children.
Download your full archive whenever you want — no questions, no friction. Keep a copy on your own drive, or hand it down on a USB stick.
Free on every plan
Order your child's mailbox as a hardcover book — letters, photos, and dates, printed on cream paper and shipped to your door.
Or pay-per-book on Free & Keeper
We don't plan to. But if we ever wind down, here's our written commitment:
Privacy & export details live in your account settings from day one.
You'll forget what they said today. You won't forget that you wrote it down.
