PurePaper - Minimalist Scanner

宇航 吴

PurePaper is a high-end document scanning tool designed for those who value both aesthetics and efficiency. We believe a tool should be invisible—it shouldn't track you, it shouldn't require a subscription, and it certainly shouldn't upload your private documents to a server. [CORE FEATURES] • The "Flatbed Look": Our adaptive thresholding algorithm eliminates shadows and gradients caused by phones or lamps, restoring a pure white background. • Precision Warping: High-accuracy edge detection and perspective correction transform skewed photos into perfectly rectangular documents. • Text Sharpening: Boosts contrast for handwriting, stamps, and printed text, making them crisp and legible. • Three Core Modes: Magic Color (preserves original ink), B&W Document (high-contrast copy), and Original Photo (geometry correction only). • Privacy First: 100% on-device processing. Your documents stay in your sandbox or your chosen private cloud (iCloud/WebDAV). [WHY PUREPAPER?] • Ultra-Minimalism: A clean, native UI inspired by Apple’s design philosophy. No clutter, just scanning. • Anti-Subscription: One-time purchase, lifetime ownership. • Performance: Built with a native Swift stack for near-instant launch and processing.
