App Features

Vision-Powered Offline Document Scanning: Capture high-quality digital scans with native Apple Vision technology. The app intelligently detects document edges, corrects perspective distortion, removes shadows, and enhances text sharpness in real time. Support single-page and multi-page batch scanning for contracts, receipts, invoices, ID documents, notes, and all kinds of paper files. All scanned images are saved locally instantly with no network transmission.
On-Device Chinese & English OCR Recognition: Conduct high-precision offline bilingual text recognition entirely on your device without internet access. Extract Chinese and English text from scanned documents accurately, and support side-by-side preview of original scans and recognized text. You can manually edit and correct text errors to ensure complete and accurate digitization results. All text data is stored locally to protect your private information.
Sensitive Information Privacy Masking: Protect confidential content before file sharing with professional local masking tools. Freely select any area on scanned documents to apply Gaussian blur or solid black mask, effectively hiding ID numbers, phone numbers, transaction amounts, addresses, and other sensitive data. Support undo and redo functions to avoid incorrect edits and guarantee flexible and precise privacy protection.
Multi-Page PDF Synthesis & Dual-Quality Export: Merge multiple scanned images into a single standard PDF file with one tap. Two export modes are available to meet different usage scenarios: high-definition original quality for long-term file archiving and compressed lightweight quality for fast sharing and transmission. All PDF files are generated locally through iOS native PDFKit, ensuring standard formatting, clear presentation, and full device compatibility.
Encrypted Local Folder Storage: Create independent password-protected local folders to store confidential and sensitive documents. You can customize and reset folder passwords at any time. All files stored in encrypted folders are locally encrypted and hidden, and can only be accessed after correct password verification. There is no cloud backup or remote synchronization, completely eliminating the risk of data leakage.
Text Copy & Multi-Format File Export: Quickly select, copy, and organize all or partial OCR recognized text for daily sorting and document arrangement. Support exporting recognized text as TXT plain text and DOCX Word formats. All exported files are automatically classified and saved in the local file library for convenient preview, renaming, and management.
Local File Management & System Adaptation: Equipped with a complete local file library to uniformly classify and manage scanned images, PDF files, and exported text documents. Support batch selection, moving, deletion, and renaming operations. Adopt minimalist modern iOS native UI design, support automatic light and dark mode switching, smooth native system animations, and full screen adaptation for all iPhone and iPad models, bringing a pure and efficient user experience.
