About DiaryVault
DiaryVault: Your life, remembered.
DiaryVault is a private memory vault on iOS, Android, and the web. You save photos, voice notes, and quick captures, then turn the ones worth keeping into Memory Cards. Echo, your AI companion, suggests the people, places, and feelings each memory connects to. You verify. Only confirmed connections become part of Your Constellation, the living map of memories that grows as you keep building.
Echo suggests. You verify. Only confirmed connections enter Your Constellation.
How It Works
Quick Capture
Save a photo, a voice note, or a quick line in the moment. It lands in Moments to Keep, no commitment required. Nothing about your life has to be polished to be remembered.
Make a Memory Card
When a moment is worth keeping, write what you want to remember about it. Echo reads your photo and your line, then suggests candidate connections: the person you were with, the place it happened, the feeling that defined it, the theme it belongs to. You confirm what's true, edit or remove what isn't, and save. The card joins Your Constellation with full provenance back to the moment that created it.
Your Constellation
Every confirmed Memory Card is a point in Your Constellation. People, places, feelings, and themes connect across cards based only on the links you verified. Nothing enters without your confirmation. The Constellation grows as you keep building, showing the threads that keep returning in your life.
Echo, your reflection companion
Beyond suggestions on each Memory Card, Echo can reflect across Your Constellation. Ask what's been on your mind this season. Notice the people who keep showing up. Surface patterns in feelings or places. Echo only reads what you've added to DiaryVault, not your email, calendar, messages, or browsing history.
Eras, Identity Snapshot, Year Review
Confirmed Memory Cards become the substrate for bigger reflections. DiaryVault clusters your memories into Eras with auto-generated chapter titles. Your Identity Snapshot summarizes who you are right now, drawn from what you've actually confirmed. Year Review is your year, written from what you actually lived.
- Reflection feed. A separate stream of your own reflections, in your own words.
- On This Day. Resurfaces Memory Cards from past years on the same date.
- Films. Turn a handful of photos into a short film with motion and music, free to make.
- Translation. Translate any entry into 11 languages with one tap.
- Social Sign-In. Google, Apple, Microsoft.
- Cloud Sync. iOS, Android, and web stay in sync.
- Private by default. Encrypted entries, no social feed, no ads, ever.
What Makes DiaryVault Different
Most journaling apps give you a blank page. The blank page is the bottleneck. Most people don't write because writing from scratch is hard, especially on the days that matter most.
DiaryVault solves a different problem. The hard part isn't writing the entry. The hard part is remembering what mattered, finding it again later, and seeing the connections between the moments of your life. Memory Cards make those connections explicit. Echo suggests them; you confirm them. Your Constellation makes them navigable.
The signal sources are narrow on purpose. Echo only reads what you've added to DiaryVault and the photos you choose for Memory Cards or Echo drafts. We don't read your inbox, your messages, your location pings, or your browsing history. Everything in Your Constellation is there because you put it there.
The doctrine does not bend: Echo suggests, you verify, only confirmed connections enter Your Constellation. This is the difference between an AI that journals for you and an AI that helps you remember what's already yours.
Who DiaryVault Is For
DiaryVault's first audience is new parents. A baby's first year is already in the camera roll: hundreds of photos, taken daily, that never become a story. DiaryVault turns those photos into Memory Cards with the details that disappear first, and the first 10 Memory Cards are free so the earliest weeks can be kept without paying.
More broadly, DiaryVault is for people who want their life remembered without having to write from scratch every day, and who don't want a journaling app reading their email, calendar, or messages to do it. If you take photos but don't journal, if you've tried journaling apps and stopped within a week, if you want a private place to keep your life that gets richer the more you build, DiaryVault is built for you.
Pricing
Free is enough to try the core loop. Capture moments, create your first 10 Memory Cards, let Echo suggest people, places, feelings, and themes, and watch your Constellation begin to form. You decide what becomes part of your memory graph.
