Write to your child across a lifetime.
Not a baby book. Not a diary about them. Momoir is where you write to them, by name, the things you want them to read one day. The funny lines. The photos. The voice notes. The hard-won advice. The truths you don't quite know how to say out loud yet.
Some letters to give today. Some sealed for the days you might not be there.
One day, all of it becomes a book they'll hold. Your words to read. Your voice to hear.

✨ Takes about a minute. Your words stay private to you.
Our promise
Every other journaling app has you write about your child.Momoir lets you write to them.
One day, when they hold this in their hands, it won't read like a report. It will read like a letter from you, written across decades, addressed by name.
How Momoir works
Three small steps. The rest is just you, writing to the person who will one day read this.
Begin a book
One book per child, at any age. Pick their name and a cover that feels like them.
Write to them
A line. A photo. A voice note. A piece of advice. Always addressed to them, never about them.
Give it to them, one day
When the moment comes, close the book and hand them everything you wrote. They were the audience all along.
A book for every age. Yours, and theirs.
Part baby book, part book of life. Whatever you want them to one day know has a place here, written in your own voice.
Firsts
Tell them about their first steps, first word, first day of school.
Quotes
The hilarious, sweet, unforgettable things they say. Saved for them.
Love notes
Tender things you want them to feel one day, addressed to them.
Milestones
Birthdays, graduations, weddings. Write to them through every chapter.
Wisdom & advice
What you wish you'd been told. What you want them to carry.
Photos & voice notes
Their giggle, your lullaby, the picture that tells it all.
What makes Momoir different
Quiet by design. Built for the moms who don't want one more app shouting for attention.
Private by default
No public feed, no followers, no comments. Ever.
Never used to train AI
Your photos, voice notes and words are not training data.
No ads, no tracking
We don't sell your attention or your data.
Guilt‑free
No streaks, no badges. Write when it matters. That's enough.
I built Momoir because I wanted somewhere quiet. Ana Paula
From a daughter who has already read her mother's letters
"This is so unique. It is both sentimental and practical. I love the sealed letter feature, where my mom is able to write to me and save her words for the moments I need her the most. Especially as a recent graduate who moved away from home, this platform helps me stay connected with my mom in a way that truly matters. Even with the distance between us, it makes her feel right there with me."
For the things you want them to know one day
"After losing my mom so suddenly, I understood what really stays. I wish I'd had her voice, her thoughts, her small moments. Now I can leave mine for my children."
"I truly think this app's idea is beautiful. Being able to write letters to my child now and imagine them reading it in the future really touches me. It's simple, but full of meaning, a way to preserve love in words."
"What a beautiful and unique app this is. Such a perfect way to leave a legacy of love and memories for my son and grandchildren to unlock one day. A time capsule of my deep love for each of them, our special moments, my prayers as they grow and for their futures. The ability to leave them voice notes is truly a treasure and so special. I wish my mom or grandmother could have done this for me."
With gratitude to the mothers who shared their words.
A note from the founder
Why I built Momoir
I'm Ana Paula.
A few days ago, I tried to remember something funny one of my children said when they were little, the exact words, the way they said it. I couldn't. I always believed I would never forget those moments, but I did.
My kids are 20, 22, and 23 now. They're grown, yet they still call me when they have a hard test, when they're sad, when they're worried. They tell me my voice calms them, and somehow, I always know what to say.
One day, I won't be there to say it.
I built Momoir so I could leave them my voice, my words, and the life we've shared. The things they may still need one day.
Every email that comes through Momoir, I read myself. If you ever write to me, I'll be there.
Ana Paula
A quiet place. Yours alone.

Read our privacy promiseOne day, they'll read this. Start writing to them.
The first letter takes a minute. Start with the one thing you'd want them to know if you could only tell them one.
Takes about a minute. Private to you.
