Superior to traditional EPUB translation
"Delivering a native-level reading experience for you. Shangyi AI is engineered for long-form reading, supporting translation of large-capacity eBooks. We not only translate the text, but also reconstruct the entire book’s structure—retaining table of contents navigation, CSS styles, and image layouts—allowing you to enjoy a seamless reading experience on Kindle or Apple Books."
Not just translating text,
but restoring the soul of your documents
Perfect Preservation of Flow Layout
The core advantage of EPUB is its adaptability to various screens. We rigorously preserve the file’s HTML/CSS structure after translation, ensuring your document reflows flawlessly on smartphones, tablets, or e-readers.
Supports files up to 500MB
Even the most extensive works can be completed in a single process. Whether you have an album with abundant high-definition illustrations or a multi-million-word tome, we handle every project reliably—no file splitting required.
Table of Contents and Link Navigation
Your book’s navigation remains fully intact. We automatically translate the Table of Contents (TOC) and update internal links, guaranteeing that each chapter title directs you precisely to its corresponding place in the translated content.
Vertical Text Support
Optimized for Japanese or Traditional Chinese books. We can recognize and accurately process vertical writing mode, preserving the original book's unique reading style.
Terminology Consistency
Lengthy novels are especially prone to inconsistent character names. Upload a glossary to ensure absolute consistency for main character names, place names, and specialized concepts across hundreds of thousands of words throughout the entire book.
Why does format matter?
- Precise formatting is the hallmark of professionalism.
- Reduce secondary formatting time.
- Ensure accurate and precise information delivery.
