PdfTranslator: Professional AI Translator Keeping Original Layout. Deeply optimized for various mainstream document types including academic papers, business contracts, patent documents, and presentations. One-tap mutual translation, keeping the original formatting intact. Now optimized for iPad, with annotation and note mode. [ Core Advantages ] - Keep Original Layout: Deeply analyzes the underlying PDF grid. The translated text is perfectly embedded into its original position. Images, charts, tables, and multi-column layouts remain fully intact without shifting, offering a native reading experience. - Dual Translation Engines: Supports both a built-in local translation engine for 100% offline translation and an AI translation engine powered by the latest large language models (LLMs). - 100% Local & Offline: With the local engine, PDF layout analysis, rendering, and translation are completed entirely on your device with zero internet dependence. Medical records, unpublished papers, and confidential business contracts never leave your device, preventing privacy leaks from the source. - Cutting-Edge LLM Driven: Say goodbye to rigid word-for-word translation. The AI engine leverages the latest large language models for deep contextual understanding and semantic reorganization, delivering precise terminology and natural, fluent translations. Only the text fragments needed for translation are sent โ€” your full document is never uploaded, and your translation data is never stored. - Smart Layout Optimization: Intelligently recognizes document elements such as titles and paragraphs. It dynamically plans the display position and font size of the translated text, optimizing readability while respecting the original layout. - Annotation & Note Mode: Mark up PDFs with pen, pencil, highlighter, and lasso tools โ€” precision-tuned for Apple Pencil with palm rejection. Take handwritten notes directly on the page while reading, alongside the translation. [ Features ] - Flexible View Modes: Switch freely among "Original Text Only", "Translated Text Only", and "Bilingual Parallel Translation" modes. - Academic Journal Adaptation: Specially optimized for mainstream academic journal PDFs, perfectly handling complex chart hyphenation and formula text wrapping. - Comprehensive Multilingual Support: Easily translate among over 20 mainstream languages, including English, Japanese, Korean, German, French, and Spanish. - Hardware Acceleration: Fully leverages the computing power of Apple Silicon chips to process hundred-page documents in seconds, providing instant local rendering without the wait. - Scanned Document Support: Built-in OCR capabilities ensure scanned PDFs and documents achieve the exact same layout recognition and high-quality translation results. - Native iPad Support: Optimized for iPadOS with Apple Pencil and Split View, delivering a seamless large-screen reading experience. [ Target Audience ] - Researchers & Students: Swiftly conquer foreign-language academic papers and seamlessly track global research trends. - Legal & Business Professionals: Review commercial contracts, industry whitepapers, and patent specifications offline with total peace of mind. - Avid Readers: Read imported original PDF e-books and long technical manuals without any language barriers.
