StayScope

Have you ever booked an accommodation based on beautiful photos, great ratings, and a reasonable price—only to arrive and realize the nearest convenience store is a 20-minute walk away, there's no subway, and you need a cab just to reach a pharmacy?

StayScope was built to solve exactly that.

Before you even click "Book," StayScope tells you in seconds:
✔ Is there a supermarket nearby? How far is the closest convenience store?
✔ Where are the nearest subway and bus stations?
✔ How far is the closest hospital or pharmacy?
✔ Are there parks, cafes, or decent restaurants nearby?
✔ What local attractions are worth visiting?

No more manually copying addresses, pasting them into Google Maps, and running individual searches.
StayScope automates all of this for you.

🌍 Local Language Search Covering 20+ Countries
━━━━━━━━━━━━━━━━━━━━━━━━━━━

When searching for listings in Japan, StayScope automatically searches for supermarkets using "スーパー" and convenience stores using "コンビニ"—instead of English terms like "supermarket in Tokyo" (which often yield poor results).

StayScope is optimized for over 20 countries and regions, defaulting to the correct keywords in the local language:

Taiwan / Hong Kong / Macau / Mainland China
Japan / South Korea / Thailand / Vietnam / Indonesia /
Malaysia / Philippines / Singapore
USA / UK / Canada / Australia / New Zealand
France / Germany / Italy / Spain /
Portugal / Netherlands / Greece / Turkey / UAE

The system automatically switches based on the listing's country—zero manual configuration needed.

━━━━━━━━━━━━━━━━━━━━━━━━━━━
💰 Price Tracking: Never Overpay Again
━━━━━━━━━━━━━━━━━━━━━━━━━━━

Every time you open the same listing, StayScope automatically records the price you see (including the currency) and displays it in the popup:

💰 NT$ 2,480 / night ↑ 15% more expensive than last time
💰 ¥ 12,800 / night ↓ 8% cheaper than last time
💰 $ 89 / night — Same as last time

Know instantly if the price has gone up or down, helping you decide if it's the right time to book.
All price history is stored entirely locally in your browser. Nothing is ever sent to our servers.

⭐ Favorite Listings + Location Score Checklist
━━━━━━━━━━━━━━━━━━━━━━━━━━━

After browsing a few properties, it's easy to forget which one had the best location. StayScope lets you save your favorite listings and creates a Location Checklist for each:

🛒 Supermarket ✅ Yes
💊 Pharmacy ✅ Yes
🌳 Park ❌ Not found
🚇 Subway ✅ Yes
🏥 Hospital ✅ Yes
🍽️ Restaurant ✅ Yes
🏪 Convenience Store ✅ Yes
☕ Cafe ❌ A bit far

The system automatically calculates a location score based on your checked items (e.g., "⭐ 7/8"), letting you see at a glance which property has the best amenities.

You can also add custom tags to your saved listings (e.g., "Kid-friendly," "Near the beach," "Business trip") for easy filtering later to find your perfect match.

━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚖️ Side-by-Side Comparison (Up to 5 Listings)
━━━━━━━━━━━━━━━━━━━━━━━━━━━

Select 2–5 listings from your favorites for a side-by-side comparison.
The comparison card displays:

▸ Country flag + City
▸ Location Score (Checklist results)
▸ Latest recorded price + Time recorded
▸ Status of each location amenity (clear emoji icons)

Say goodbye to the nightmare of switching between 10 open tabs.

Advanced users can click "Full-Page Comparison" to view all listing details simultaneously on a dedicated page. It also supports one-click sharing of your comparison results (in plain text format, perfect for pasting directly into LINE or WhatsApp to discuss with travel companions).

━━━━━━━━━━━━━━━━━━━━━━━━━━━
🎒 Quick Travel Type Switching
━━━━━━━━━━━━━━━━━━━━━━━━━━━

Different trips require completely different amenities.
StayScope provides 6 travel type presets (quick switch buttons):

🎒 Backpacker — Supermarkets, Pharmacies, Subway/Metro, Cafes
👨‍👩‍👧 Family — Supermarkets, Pharmacies, Parks, Hospitals
💑 Couples — Restaurants, Cafes, Parks, Convenience Stores

━━━━━━━━━━━━━━━━━━━━━━━━━━━
📏 Adjustable Search Radius
━━━━━━━━━━━━━━━━━━━━━━━━━━━

Looking for a supermarket within 500 meters? Or an airport within 3 kilometers?
StayScope supports 5 different search radius options: 500m / 1km / 2km / 3km / 5km.
Adjust it with one click in the settings page, or toggle it directly during individual searches.

━━━━━━━━━━━━━━━━━━━━━━━━━━━
🛠️ Custom Search Categories
━━━━━━━━━━━━━━━━━━━━━━━━━━━

The default 23 categories cover most needs, but if you have specific preferences—like "Organic grocery stores," "Pet-friendly cafes," "Hot springs," or "Yoga studios"—you can easily add custom search categories in the settings. Your custom search buttons will then appear on the main interface, completely personalized for you.

━━━━━━━━━━━━━━━━━━━━━━━━━━━
🌐 12 Interface Languages
━━━━━━━━━━━━━━━━━━━━━━━━━━━

The StayScope interface itself supports 12 languages:

Traditional Chinese / Simplified Chinese / English / Japanese /
Korean / Thai / Vietnamese / Indonesian /
Malay / Spanish / French / German

The system automatically detects your Chrome browser's language, or you can manually switch it in the settings. No matter your native language, you can use StayScope in the most intuitive way possible.

━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔒 100% Offline, Zero Backend, Full Privacy
━━━━━━━━━━━━━━━━━━━━━━━━━━━

StayScope requires no account, no logins, and doesn't connect to any servers.

All data (favorites, checklists, price history, settings) is stored locally in your own Chrome browser:
▸ chrome.storage.sync — Automatically syncs across your personal devices via your Google account.
▸ chrome.storage.local — Used for larger local data (like price history).

No ads. No usage tracking. No analytics SDKs.
Risa Studio will never know where you are searching or which listings you've saved.

All page information read by StayScope (coordinates, prices, listing names) is the exact same public information visible to any visitor—we don't do anything beyond what is strictly necessary.

━━━━━━━━━━━━━━━━━━━━━━━━━━━
