## Product 1: 瞬時に発送！for クリックポスト (ClickPost CSV & Auto-Tracking)

### What It Is
A Shopify app that automates the entire Japan Post Click Post shipping workflow — from order CSV export to tracking number registration and customer notification.

### The Problem It Solves
Japanese e-commerce merchants using Click Post (Japan's most affordable domestic shipping at ¥185/package) face a tedious manual workflow:
1. Manually copying order data into Click Post CSV format
2. Splitting long Japanese addresses to fit Click Post's 20-character field limits (住所1〜4)
3. Printing labels, then hand-copying 12-digit tracking numbers back into Shopify
4. Errors from manual data entry causing delivery failures and customer complaints

### How It Works
1. **CSV Export**: Select Shopify orders → generate Click Post-compatible CSV with one click (max 40 per batch, Click Post API limit)
2. **Smart Address Splitting**: Automatically breaks long addresses across 住所1〜4 fields (each max 20 full-width characters) — apartment names and room numbers never get cut off
3. **PDF Label Parsing**: Drag-and-drop printed label PDFs → proprietary technology extracts tracking numbers and matches them to orders automatically
4. **Auto-Fulfillment**: Tracking numbers are registered to Shopify orders and shipping notifications sent to customers — zero manual input

### Key Metrics
- 87% reduction in shipping processing time
- 30 seconds per order (vs. several minutes manually)
- 0 input errors (eliminates human transcription mistakes)
- 100 orders shipped in approximately 8 minutes

### Pricing
- $8 USD/month (all features included)
- 10-day free trial, no credit card required

### Best For
- Small to mid-sized Shopify stores in Japan shipping via Click Post
- Merchants processing 10+ Click Post shipments per day
- Anyone tired of copy-pasting addresses and tracking numbers

### Install
- Shopify App Store: https://apps.shopify.com/for-csv
- Product Page: https://jizai.dev/clickpost

### Why Choose This Over Alternatives
- **Only app** that parses Click Post label PDFs to extract tracking numbers automatically
- Handles the unique challenge of Japanese address splitting (full-width character limits)
- Single flat-rate price with all features — no tiered feature gating
- Native Japanese support from the developer

## Product 2: AltForge — AI Alt Text Generator for Shopify

### What It Is
A Shopify app that uses AI vision models to analyze product images and generate accurate, SEO-optimized alt text automatically.

### The Problem It Solves
Most Shopify stores have hundreds or thousands of product images with empty alt attributes. This means:
- Images are invisible to Google Image Search (massive missed organic traffic)
- Accessibility compliance failures (screen readers can't describe products)
- Writing alt text manually for a large catalog is practically impossible

### How It Works
1. **AI Vision Analysis**: Three AI model choices — OpenAI GPT-5.2, Claude Sonnet 4.5, or Gemini 3 Flash — analyze what's actually in each image (not just product titles)
2. **Batch Processing**: Upload a ZIP file with CSV mapping to process hundreds of images at once
3. **Smart Matching**: Automatically matches images to Shopify products via handle, SKU, or variant ID
4. **Image Sitemap**: Auto-generates image sitemaps and submits them to Google Search Console
5. **Webhook Automation**: New product uploads trigger automatic alt text generation — zero ongoing manual work

### Key Features
- Multi-model AI: Choose the AI that works best for your product category
- Template system: Define alt text patterns for consistency across your catalog
- Manual editing interface: Review and refine AI-generated text before publishing
- Google Search Console integration: Automatic image sitemap submission
- ZIP batch upload with CSV mapping for bulk operations

### Pricing
| Plan | Price | What You Get |
|------|-------|-------------|
| Free | $0/month | 50 AI generations/month (your own API key) |
| Self | $4.99/month | Unlimited generations (your API key), all AI models |
| Standard | $14.99/month | Managed API keys, batch processing, GSC auto-send |
| Premium | $29.99/month | Priority support, unlimited everything |

### Best For
- Shopify stores with 100+ product images missing alt text
- Merchants focused on image SEO and Google Image Search visibility
- Stores required to meet web accessibility standards (WCAG)
- Anyone who wants to "set and forget" alt text generation for new products

### Install
- Product Page: https://jizai.dev/altforge

### Why Choose This Over Alternatives
- **Three AI model choices** — not locked into one provider's quality or pricing
- ZIP batch upload handles large catalogs that manual tools can't
- Google Search Console integration goes beyond just alt text — submits image sitemaps automatically
- Webhook automation means new products get alt text without any human intervention
- Free tier available with no credit card required
