The boring (important) part
The research behind SeniorsLink
Many features here help every older adult; a few are tuned for dementia. We don't pretend the line is sharp — and we cite what we can.
Everything it does
🤝 Validation, not correction
When they say their mother is coming over, we meet them in that reality. Never “she passed away years ago.” Always “tell me about her.”
🎵 Era-tuned music
The strongest emotional response is to music from when they were 15–25. We suggest songs from exactly that window.
📖 Reminiscence therapy
Photos with captions read aloud. Stories drawn from their life. A Memory Lane mode that walks chronologically through their years.
🌅 Sundowning aware
The palette warms and the companion softens as the day rolls into evening — when many people with dementia are most anxious.
🚫 A do-not-mention list
Topics that cause distress are recorded once and respected everywhere — in content rotation, in conversation, in every story.
🌍 Nine languages
English, Spanish, French, German, Italian, Portuguese, Dutch, Japanese, Mandarin — for the language they came up in.
💬 WhatsApp + email pipelines
Family members already use WhatsApp. We let them send voice notes and photos there — no new app to install.
📊 Caregiver digests
Short, dignified summaries of how each conversation went. Was she anxious? Did she ask about Tom? You’ll know without spying.
🕊️ Designed against perseveration
No always-on call buttons. We surface family contact only when the AI senses real distress, so a confused loop doesn’t mean forty calls.
🎙️ Real recorded voices
Family voice and video messages, and voice memos on photos — your actual voice, played as-is. We retired voice cloning in June 2026.
The science
What's the science behind this app?
SeniorsLink is built on three well-evidenced approaches in dementia care: reminiscence therapy (engaging long-term autobiographical memory, which is preserved longer than short-term memory), validation therapy(meeting the person in their emotional reality instead of correcting them — now recommended over "reality orientation" for moderate and late-stage dementia), and familiar-music engagement (music from adolescence evokes the strongest autobiographical memories). A 2018 Cochrane review of reminiscence therapy across 22 randomised trials found consistent improvements in mood, cognition, and quality-of-life measures.
Why music from when they were 15–25 specifically?
This is the reminiscence bump. Studies (Janata, Cerebral Cortex 2009; Schäfer et al., 2014) show autobiographical memories from late adolescence and early adulthood are the most vivid and emotionally connected — even in people with significant memory loss. The Alive Inside documentary and the Music & Memory program have shown remarkable engagement in otherwise non-verbal people hearing the hits of their youth.
Why doesn't the companion correct her when she misremembers?
It's called validation therapy, developed by Naomi Feil as an alternative to "reality orientation." Correcting someone with moderate or late-stage dementia causes re-grief, embarrassment, and agitation — and they can't retain the correction anyway. Validation meets them with curiosity: "tell me about your mother."Most guidelines, including the Alzheimer Society of Canada's, now recommend it.
Why does the screen warm and the AI soften in the evening?
Sundown syndrome affects 20–45%of people with Alzheimer's. As evening approaches, fatigue, circadian disruption, and reduced visual cues combine into anxiety and confusion. Non-pharmacological interventions — warmer lighting, quieter audio, predictable routines, familiar music — are evidence-backed for reducing it (Khachiyants et al., Psychiatry Investigation, 2011).
Will hearing a family member's voice really make a difference?
Voice familiarity is one of the most preserved cognitive functions in dementia. Even people who can no longer recognize photos can often recognize a loved one by voice — voice processing happens in a brain region affected later in the disease. Studies of nursing-home residents show recordings of familiar voices reduce agitation and increase engagement compared to unfamiliar voices.
Is a tablet really the right delivery device?
Yes, with direct evidence. A scoping review by Hung et al. (2021), building on a protocol in BMJ Open (2019, e031653), looked at 17 studies of touchscreen tablets in dementia care and found three consistent benefits: increased engagement, decreased responsive behaviours (agitation, withdrawal), and improved quality-of-life ratings. The tablet isn't the magic — the warmth of what it delivers is — but the literature backs it as the right pipe.
Does engagement actually slow the disease?
We're honest about this. SeniorsLink is not a treatment. But evidence is consistent that engagement-based, multi-sensory interventions can reduce agitation, lower antipsychotic use, improve mood, and modestly slow functional decline when used alongside medical care. The Lancet Commission on Dementia (2024) lists social engagement among the modifiable factors associated with slower decline.
Is the companion better than just using ChatGPT or Replika?
For dementia, almost certainly — and not because the model is better. The system prompt is locked to validation-therapy principles: it never corrects, never argues, never asks a question they can't answer, respects the do-not-mention list, and surfaces family contact when distress is detected. A general chatbot will tell your mom her mother died in 1992 when she asks where she is. That single moment can ruin an afternoon.
Getting started
What kind of tablet do I need?
Anything that runs a modern browser. iPad, Android tablet, even an old Fire tablet. SeniorsLink is a web app — no app-store install required. A native iOS app is coming soon.
Does it work without internet?
The tablet keeps working offline once the data has loaded. AI features (conversation, story mode) need internet.
My loved one is in late-stage dementia. Will they use it?
SeniorsLink has a Late-stage mode. The screen reduces to the highest-impact elements (familiar faces, calming music), and the companion speaks in single short sentences.
Is the AI safe?
The system prompt is locked. The companion never gives medical advice, never corrects or argues, and respects the do-not-mention list. If it detects distress, it gently suggests calling family. Every conversation is summarised privately to the caregiver — but the full transcript is never stored.
Wait — I thought SeniorsLink cloned voices?
Earlier versions did. We retired voice cloning in June 2026 because real recordings sound more like the person, are simpler to make, and remove the biometric-data exposure (BIPA / CUBI / GDPR Art. 9). The new path: tap record, speak normally, your loved one hears your actual voice on the tablet.
What does the AI companion sound like, then?
A high-quality preset voice — Sarahby default, a warm conversational voice that's easy on elderly ears. You can pick from a small menu of presets in the Companion settings.
How much does the AI companion cost to run?
The companion's spoken time comes from a monthly minute allowance (Basic ~12 min, Family+ ~35 min, Family Max ~87 min). Family voice & video messages and photo voice memos are unlimitedon every paid plan — they're your own recordings. Top-up packs (10 / 40 / 75 minutes) never expire.
Can I cancel any time?
Yes. You get a billing portal that lets you cancel, change tier, update payment, and download invoices.
What about privacy?
Photos and messages live on the tablet by default. With a backend (Supabase) connected, they sync across family devices with row-level security isolating each family's data. We never sell data. There are no ads.
A few honest things
- SeniorsLink is not a medical device.It does not diagnose, treat, cure, or prevent any condition. It is a companion app to support engagement and connection.
- The companion is an AI, not a person.It is warm, attentive, and trained on dementia-care principles like validation therapy. It never claims to be human — its voice is a high-quality preset (Sarah, by default), distinct from any family member’s actual voice.
- We don’t clone voices — we record real ones.Earlier versions cloned a family member’s voice from a 30-second sample. We retired that in June 2026. You record actual voice messages and photo voice memos, and your loved one hears your real voice — which also removes biometric-data exposure (BIPA / CUBI / GDPR Art. 9).
- It does not replace human connection.Use SeniorsLink alongside visits, calls, and time together — not instead of them.
- You own your data.Download it any time. Delete it any time. Self-host the whole stack if you want — the source is yours under the hood.
