NAMU

One line a day, peace of mind recorded. Your storybook for family after a year.

Inspiration

Loneliness and the fear of being forgotten quietly erode peace of mind- especially for older adults who spend long stretches alone. We asked: what if calm didn't come from "emptying the mind," but from making meaning-capturing stories, being heard, and gently connecting with family? That became NAMU: a psychological companion that turns anxiety into legacy and loneliness into connection.

  • Human purpose we serve: the need to feel seen, heard, and that one's life mattered-especially in late life.
  • Deep pain: long hours alone, fear of being forgotten, nights that don't "close" with meaning.
  • Macro trends (urgency): rapid population aging, more elders living alone, dispersed families, seniors using smartphones but avoiding complex UIs.
  • Why us: we translate reminiscence science into a 90-second daily ritual that creates immediate calm and near-term connection-not just logs.

What it does

  • One gentle prompt a day (text or voice): "Can you recall a nickname…?"
  • Edit-Lock: entries are safely locked to quiet perfectionism and over-editing.
  • Active listening → specific follow-ups: NAMU analyzes the entry and asks a personal, context-aware question (not a generic prompt).
  • Senior-first UX: large type, high contrast, minimal motion, voice input.
  • Family Bridge (optional): share a single story to loved ones with one tap.
  • Autobiography over time: simple, cumulative, zero overwhelm.
    Toothbrush test: A nightly, 90-second ritual people want to use. If daily completion probability is rrr, expected monthly stories =30r=30r=30r. A small nudge Δr=0.1\Delta r=0.1Δr=0.1 yields +3+3+3 more preserved memories/month-each a chance for family connection.

How we built it

  • App: React Native (Expo) with TypeScript; voice input via on-device STT; TTS for gentle read-backs.
  • Backend: Firebase/Firestore for entries & permissions; Cloud Functions for async processing.
  • AI: Prompt-chained LLM for (1) understanding the memory, (2) drafting the specific follow-up, (3) producing a short validation message, (4) generating tomorrow's connected prompt + keywords.
  • Safety & privacy: content moderation step; PII-light schema; "share" uses per-recipient consent tokens; delete-on-device cache; simple Lock primitive that prevents accidental edits.
  • Design system: senior-first components (44+ pt defaults), focus states, high-contrast palette, and a single primary action per screen.

Challenges we ran into

  • Grounding AI in this person's story without drifting into generic advice.
  • Emotionally heavy memories: crafting copy that validates without re-traumatizing; adding a one-tap "lighten the prompt" option.
  • Over-editing habit: users kept polishing; the Lock pattern reduced friction and improved completion.

Accomplishments that we're proud of

  • A tight daily loop: prompt → lock → specific follow-up → validation → tomorrow's thread.
  • The Family Bridge that converts private reflection into present-day connection.
  • A calm, dignified interface older adults can actually navigate on the first try.
  • An AI flow that feels like listening-not just generating text.
  • We operationalize reminiscence evidence into a product people actually use daily.

What we learned

  • Calm often follows being heard, not silence.
  • Specific, situated follow-ups beat generic prompts for engagement.
  • Tiny rituals (same time, one screen, one action) are stronger than big features.
  • "You've shared wisdom" lands better than achievement badges for this audience.
  • Accessibility isn't a checklist-it's a design language (contrast, spacing, motion, copy tone).
  • "You've shared wisdom" resonates more than badges or streak flames.

What's next for NAMU

  • Care-circle channels: group sharing to a small, private circle (family, caregiver).
  • Printed keepsakes automation: in-app proofing and one-tap order.
  • Multilingual support (e.g., Korean ↔ English) so families can read across languages.
  • On-device personalization: lightweight local memory of themes to deepen follow-ups.
  • Clinically informed modes: optional guardrails and resources when heavy topics appear.
  • Research collab: pilot studies to quantify changes in loneliness/anxiety and adherence.
  • Insertion (fit): lives between wellness and communication-a home ritual that optionally spills into existing family chats.
  • *Acquisition (bowling-pin):
    *
    • Adult children gift Namu to a parent →
    • Senior centers run "30-day Story Month" →
    • Caregiver networks adopt prompts as conversation starters →
    • Community/faith groups host themed months; libraries offer print-on-demand booklets.
  • Roadmap: care-circle channels, multilingual support (e.g., Korean ↔ English), on-device personalization, clinically-informed guardrails, automated booklet proofing/ordering.
