## The Problem It Solves

Paper lunch menus handed out by schools and nurseries get dirty on the fridge, are hard to read, and can't be checked when you're away from home. Answering your child's daily "What's for lunch today?" question is surprisingly inconvenient. Lunch Box uses AI technology to solve these everyday frustrations.

## Key Features

### Menu Scanning (献立表スキャン)
Photograph a paper lunch menu sheet and AI (Gemini 1.5 Flash) automatically recognizes the menu text and organizes it by date. Manual text input is also supported. A single scan registers an entire month of meals, so you only need to do it once at the beginning of each month.

### AI Image Generation
From the registered lunch menu, Gemini AI (Imagen 3) automatically generates cute bento-style illustrations. The images feature warm pastel-colored designs that are friendly and appealing to children.

### Home Screen Widget
Display the generated bento image as an iOS home screen widget. Just glancing at your phone each morning shows you today's lunch — no need to open the app. Available in Small and Medium sizes.

### Calendar View
View a full month of school lunches in calendar format. You can also check past lunches, making it easy to plan dinner around what was served at school — for example, "Today's lunch was fish, so let's have meat for dinner."

### Collection
Bookmark and save your favorite bento images. Enjoy collecting the unique AI-generated illustrations.

### Sharing
Easily share generated bento images via LINE, Instagram, and other social apps. Popular for sharing in parent group chats.

## Paper Menu vs. Lunch Box

| Paper Menu | Lunch Box |

| Gets dirty or lost and becomes unreadable | Digital records preserved indefinitely |
| Digitizing requires tedious manual entry | One camera scan registers an entire month |
| Text-only — hard to visualize the meal | AI creates cute bento images for every dish |
| Difficult to share with family members | Easy sharing via LINE and social apps |
