Where everyday moments become the story of a lifetime.

※ what's inside ※

How Kaiary works.

Ask, and find.

“Show me Kaia at the beach last summer.”

Search your family's memories with plain language. Kaiary understands what's in your photos and what you wrote about them — so you find the moment, not just the file.

Faces, known.

Your people, recognized everywhere.

Kaiary's AI learns your family's faces from just a few photos. Browse every picture of grandma, or every shot where the kids are together — automatically grouped, completely private.

Voice in. Story kept.

Can't type? Just talk.

Record a voice note while the memory is fresh — in the car, at bedtime, holding a sleeping baby. Kaiary transcribes it and makes it searchable forever, so you never lose the details a photo can't capture.

One family. One story.

Everyone captures. Everyone belongs.

Mom snaps a photo. Dad leaves a voice note. Grandma adds a memory from across the country. Kaiary brings it all together into one shared family journal — so no one's perspective is missing.

※ privacy is non-negotiable ※

Your family's
memories,
only ever yours.

Every AI model that processes your photos runs on private infrastructure — never routed through OpenAI, Google, or any third-party AI service. Each family's data is isolated and encrypted. Your child's face is never training someone else's algorithm.

Private AI infrastructure

Face recognition, captions, search — all running on dedicated, isolated servers. Never routed through third-party AI.

No third-party AI. Period.

Your photos never leave our infrastructure. Your child is never training data for someone else's model.

Encrypted & family-scoped

All data is encrypted at rest and in transit. Every request is authenticated to your family — no one else can access your memories.

Yours forever

We never lock you in. Your data, your rules, your timeline.

※ a note from renji labs ※

“When my second daughter was born, I realized how much I had already missed with my first. Not the milestones. I had photos of those. But the small things. The way she said 'banana.' The bedtime song she only wanted for a month. The face she made the first time she tried ice cream.

Those were already fading, and no photo album was going to bring them back.

I wasn't going to let that happen twice. So I built Kaiary. Something private. Something that actually understood my family and could hold onto the moments that photos alone can't capture.

I named it after my daughter, Kaia. She's the reason all of this exists.”

Questions, answered.

Is Kaiary really private?

Yes. All AI — face recognition, photo captions, search, storybook generation — runs on servers we own. Your photos are never sent to OpenAI, Google, or any third-party AI. Each family's data is isolated and encrypted.

How is this different from Google Photos or iCloud?

Google Photos and iCloud store your files. Kaiary understands them. You can ask “when did she first ride a bike?” and get the answer. You can record a voice note at bedtime and find it linked to that day's photos months later. And nothing you store is ever used to train an ad algorithm.

What can I actually capture?

Photos, videos, voice recordings, and written journal entries. Kaiary's AI automatically captions your photos, recognizes family members' faces, and makes everything searchable by who and what's in it — not just when it was taken.

When will it be available?

We're launching on iOS first, with Android coming soon after. Join the waitlist and we'll let you know the moment each platform is ready.

Will I get spammed if I sign up?

No. We'll send you one email when Kaiary launches. That's it. We're building a privacy company — we're not about to spam you.
