First day of kindergarten
You wore the blue dress with the strawberries. We walked the long way so we'd pass the bakery, and you held my hand the whole block.
6weeks in a row
Write to the adult your child will become. Momento holds every letter, voice memo, and photograph in a private vault — sealed until their eighteenth birthday.
You wore the blue dress with the strawberries. We walked the long way so we'd pass the bakery, and you held my hand the whole block.
We send one prompt. You write a sentence, record a voice memo, or both. Years from now, your child opens the vault and finds you waiting.
A gentle Sunday-night nudge. "What does this summer smell like to you?" Two sentences. Three. Whatever you have.
Voice memos capture what writing can't — the laugh, the long pause, the sound of you when you were the parent of a five-year-old.
Everything is encrypted and sealed. You won't get nostalgic on a Tuesday. Your future child will, on a morning that matters.
Texts fade. Photos forget context. A two-minute voice memo from when your daughter was four is something photographs can never give back.
Recording — she'll hear your voice on her 18th birthday.
Neither parent can read the other's entries. Both will be read together — by your child, when they turn eighteen.
Single parent, co-parenting together, or co-parenting apart — Momento works for all of it. Each parent has their own private journal that even the other parent can't read.
One weekly streak. One free pass per month. Miss a week and we won't make you feel bad — we'll just remind you that one sentence is enough to start again.

You're trusting us with letters that need to outlive most software companies. We've thought hard about that.
Every January, we generate a beautifully-typeset PDF and a ZIP of all your raw entries and voice memos. Yours to keep, on your terms, regardless of what happens to us.
For each year, an optional hardbound book — letterpress cover, archival paper, voice memos as QR codes printed in the margins. Premium only, $48 per year.
Every encrypted vault is mirrored to an independent legal escrow with a 100-year retention agreement. If Momento ever goes away, your child still gets the email on their eighteenth birthday.
Two things, neither of which require you to do anything. First, every entry is mirrored to a third-party legal escrow under a 100-year retention agreement. Second, you can export everything as a PDF or ZIP at any time — and we automatically email you that export every January.
No. The vault is sealed by design. Even we can't read your letters — they're end-to-end encrypted with a key that's only released to your child on the unlock date you choose. Most parents pick 18, but you can choose any age between 12 and 30.
You both write separate, completely private journals. Neither parent can read the other's entries — but your child reads both timelines, side by side, when the vault opens. It works for couples, separated parents, single parents with a chosen second adult, anyone.
Free for unlimited text entries, photos, and voice memos. Premium is $48 a year and adds the hardbound printed book, unlimited co-parent invitations, and offline-first sync. There's no in-app advertising and we don't sell data — your subscription is how this works.
The vault still opens on the unlock date you set. You can also designate a trusted person who receives a one-time notice if the app detects six months of inactivity, so they can confirm the unlock date or pass along context. Your child still gets every letter.
You have until the vault unlocks to edit or delete any entry. Drafts auto-save while you write. We'd rather you write the messy, honest thing now and reshape it later than not write at all.
Four minutes. One sentence. The vault is patient.
