Features

• Batch Testing - Queue multiple prompts and run them sequentially with pass/fail tracking
• Prompt History - Persists prompts across sessions with success rate indicators
• Gallery View - Thumbnail grid of all generated images with filtering
• Side-by-Side Comparison - Generate the same prompt in all 3 styles (Illustration, Animation, Sketch)
• Export Formats - Save as PNG, JPEG, or HEIC with quality options

Quick build (command line)

# Build with Swift Package Manager
swift build

# Or build the .app bundle directly
swiftc -parse-as-library \
    -o ImagePlaygroundTester.app/Contents/MacOS/ImagePlaygroundTester \
    Sources/ImagePlaygroundTesterApp.swift \
    -framework AppKit \
    -framework ImagePlayground \
    -framework SwiftUI \
    -framework UniformTypeIdentifiers

Run

open ImagePlaygroundTester.app

Data Storage

The app stores data in:

~/Library/Application Support/ImagePlaygroundTester/
├── prompt-history.json
├── session-results.json
└── images/
    └── YYYY-MM-DD/
        └── {uuid}.png

Notes

• The app must remain in the foreground during image generation (API requirement)
• Keep the window focused while generating, especially during batch operations
