Dementia Conversation Cue Cards is a startup idea for dementia caregivers and family caregivers. A parent with dementia brings up the same conversation again and again, and the caregiver is emotionally drained inventing an answer every time. A thread in r/AgingParents drew 165 upvotes and 94 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Notes app and Dementia support forums, and that still leaves this job open. Hotness is 4.05, Scorching. Strong pain. Some willingness to pay. The thread drew 165 upvotes and 94 comments. No real solution exists. A 1-2 week mvp. A first version is weekend-easy, about 2 weeks, priced under $10 a month and charged as a free tier and a paid upgrade. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Left out on purpose
Replacing notes app. Version one does the one job above and stops there.

Market size · estimate
How big this could get
A bottom-up estimate for Dementia Conversation Cue Cards: real customer counts × a realistic price. Not a forecast.
$278M a year
5.8M caregivers · 50% of US unpaid dementia caregivers
$81.6M a year
1.7M caregivers · online, through dementia groups
$1.2M a year
26,000 caregivers · 1.5% of the reachable segment in three years
What that means
26,000 caregivers at $4/mo = $1.2M ARR
Medium confidenceHow we estimated this
- Base: 11,500,000 US unpaid dementia caregivers.
- Has the problem: 50% (assume half would use conversation aids).
- Revenue per caregiver: $48 per year ($4/mo).
- Reachable: 30% (online, through dementia groups).
- Three-year capture: 1.5% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Is this idea already taken?
People already use Notes app, Dementia support forums. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Weekend-easy. A tight MVP is about 2 weeks (2 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is dementia caregivers and family caregivers. Charge a free tier and a paid upgrade, and test a price under $10 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
