TwinPixCleaner

v2.2.0Apache 2.0

AI-Powered Visual Duplicate & Similar Photo Cleaner for macOS

Releases View Repository

A native macOS utility built with SwiftUI and Apple Vision Intelligence that accurately detects duplicate photos, visually similar shots, burst series, and edited screenshots without uploading a single pixel to the cloud.

Technology Stack & Frameworks

Swift 6.0SwiftUIApple Vision Framework (Rev2)Accelerate SIMD (vDSP)PhotoKitAppKit

Key Features & Capabilities

•Dual Scanning Engines: Pure SHA-256 binary hash matching and Apple Vision ML feature prints.
•Transitive Union-Find Clustering powered by Accelerate SIMD vector distance math (vDSP_distancesq).
•Native Apple Photos integration via PhotoKit to securely inspect your entire iCloud library.
•Persistent on-disk similarity cache for lightning-fast incremental subsequent scans.
•Interactive Skipped Files Inspector sheet with search, categorizations, and clipboard export.
•Safe non-destructive deletion with macOS Trash / Recently Deleted integration and ⌘Z instant Undo.
•Native Quick Look (Spacebar) preview, keyboard shortcuts, and full VoiceOver accessibility.

System Architecture Highlights

High-performance ML feature extraction running locally on Apple Neural Engine / GPU.
Zero-allocation SIMD vector math for clustering thousands of photo embeddings in milliseconds.
Zero telemetry, zero external network calls — 100% offline privacy guarantee.

NanoPress

v1.0.0Apache 2.0

Private, Local-Only Parallel Batch Compressor for Images & PDFs

Releases View Repository

A lightning-fast native macOS utility built with SwiftUI and Swift Concurrency to compress JPG, PNG, HEIC, TIFF images, and PDF documents locally on your device with zero cloud uploads.

Technology Stack & Frameworks

Swift 5.9+SwiftUISwift Concurrency (Actors, TaskGroup)CoreGraphicsImageIOPDFKit

Key Features & Capabilities

•100% Local Processing: Zero cloud uploads, zero tracking, and zero latency.
•Multi-Format Image Compression: Supports JPG, PNG, HEIC, and TIFF with custom quality sliders.
•Dual-Engine PDF Optimization: Standard mode for sharp quality and Aggressive mode for maximum size reduction.
•High-Throughput Parallel Batch Engine: Uses Swift Actors and Task Groups to process hundreds of files concurrently.
•Live Size Savings Preview: Inspect before-and-after byte reductions before committing.
•Drag-and-Drop Workflow: Seamless drag-and-drop ingestion with adaptive Light and Dark mode.

System Architecture Highlights

Actor-isolated pipeline preventing thread race conditions during heavy multi-core batch compression.
Direct CoreGraphics and ImageIO pipeline for memory-efficient streaming without buffering entire archives.
Native Swift Package Manager architecture with clean MVVM separation.
