kioku isA quiet voice when memory slips.
An audio-first second brain for people living with dementia and memory loss, set up by the people who care for them.
good morningYour day, gently.
Each morning Wren walks through what's ahead: who's coming, when meals are, what's planned. One calm summary, nothing to remember.
who's this?That's Maya.
Everyday camera glasses and a phone whisper a name as someone approaches, before the greeting. There is no screen to learn.
the right oneThe right tablet, at the right time.
Medication details come from a list the caregiver has checked, never guessed, so Wren always names the right one.
the hard partKnowing when to stay quiet.
A rules engine weighs every prompt against an interruption budget. It speaks when it helps, stays silent when unsure, and logs the reason.
private by designOnly those who said yes.
It recognizes a consented circle, matches faces on the phone, and discards everyone else's frames.
and if one is missedAsked once. Never louder.
Wren asks again in the same calm words. If the tablet still isn't taken, the caregiver gets a quiet heads-up instead.
and nextThe way home.
Guided walks past familiar landmarks, a caregiver app, and a private data home for every care home.
at the end of the dayGood night.
A gentle close to the day for the person, and a short note for the caregiver on how it went.
Why Kioku
Millions of people live with memory loss, and most of them are looked after by family. The help they need is constant, small and repeated: what day it is, who just walked in, which tablet, which door.
- 57 million
- people were living with dementia worldwide in 2021, with nearly 10 million new cases every year. (WHO)
- 5 hours
- of care and supervision a day, on average, from family and friends of someone living with dementia. (WHO)
- 19 billion
- hours of unpaid care given in 2025 by nearly 13 million Americans looking after someone with Alzheimer’s or another dementia. (Alzheimer’s Association)
For the person
A calm voice that answers the same question the same way, every time, without a sigh. More of the day can be done on their own, in their own home, for longer.
For the caregiver
Wren takes the small, repeated prompts: names, reminders, the way back to the room. That leaves you time to rest, and the moments with you can be about being together, not keeping track.
For care homes
Every resident gets a patient, personal prompt when staff can’t be in every room. Staff see a short note of what was asked and what was missed.
Built on trust
Wren only says what a caregiver has written and checked, recognizes only people who said yes, and keeps faces on the device. It stays quiet unless it’s sure.
Wren supports daily living. It doesn’t diagnose or treat anything, and it doesn’t replace a caregiver. It gives them some room to breathe.

Routines and reminders, a "who's this?" photo lookup, and geofencing with wandering alerts.
- Phase 2

Face prompts through everyday camera glasses, and "take me home" guided by landmarks a caregiver records in one walk through the building.
- Phase 3
An optional visual layer
Gentle overlays, help finding misplaced objects, and memory of recent conversations.

Care homes and more devices
An on-site box that keeps each home's records in that home, an orchestrator tuned by what actually helps, and support for more glasses and an iOS hub.
