SMILE: See More of Islands' Landmarks and Events
Every postcard is a quest. Every mailbox is a finish line.

THE PROBLEM
Post offices around the world are going quiet as people stop sending letters, and in the Philippines many
small towns with beautiful landmarks and festivals rarely see tourists. Home-based makers (nano
entrepreneurs) who weave hablon, bake piaya or craft Capiz shell have no physical store, so travelers never
find them. Local governments also lack clear data on which places draw visitors and which need a push.

WHAT I BUILT
SMILE is a mobile web app (PWA) that turns travel in Western Visayas and the Negros Island Region into a
postal adventure. I built it solo during the hackathon, starting October 27, 2026; nothing existed before.

- Travelers buy SMILE postcards (stamp included) from local merchants, plan their day with Isidro, an AI
  travel buddy they can talk to, and scan the postcard's QR at each landmark to collect stamps and rank up
  from E to SSS.
- "Near me" uses GPS so Isidro points to the nearest eats, landmarks, festivals, shops and inns, with a blue
  route in Google Maps.
- At the nearest post office they mail their postcard and adopt a random one from another traveler to
  follow that person's journey, bringing people back to the post office.
- Nano-Shops let home-based makers sell online: Add to Cart, PayMongo checkout (GCash, Maya, card), delivery
  by SMILE riders with an order tracker, and daily rider and weekly merchant settlement through a Post
  Office portal.
- An LGU and DOT Partner portal shows anonymous totals: check-ins, local vs foreign travelers, purchases at
  local merchants, and AI insights on what is working.
- A Hotline button keeps 911, the Red Cross (143) and verified local emergency numbers one tap away.

META MODELS
- Muse Spark: Isidro's chat and trip plans in Hiligaynon, English or Tagalog; Near me suggestions; landmark
  photo checks; journal polishing and translation; safety checks; merchant listings; partner insights.
- Muse Voice Transcribe: talk to Isidro and speak your travel journal.
- Muse Image: the AI photobooth "CONQUERED" postcard.
- SAM 3.1: finds the product in merchant photos and promo videos for close-ups.

TECH
Vanilla JavaScript PWA on GitHub Pages, Google Apps Script backend with Google Sheets and Drive, the Meta
Model API, and the PayMongo Checkout API. API keys stay on the server only. Traveler addresses are shared
only with the rider who claims the order, following the Philippine Data Privacy Act.

IMPACT
SMILE brings travelers to small towns, gives nano entrepreneurs and riders a way to earn, gives post offices
a new reason to be visited, and gives local governments data to grow tourism. It starts with 8 provinces and
73 places and is designed to scale to the whole Philippines.
