Ebook translation FAQ
Can I translate a 50 000 to 100 000-word novel?
Yes. AI Glot is designed for large-scale document translation. It processes all chapter files systematically while maintaining stylistic coherence throughout the manuscript.
Will chapter formatting and italics be lost?
No. AI Glot parses XHTML tags (such as
<em>, <strong>, and custom class spans) as structure. The narrative text is translated around them, leaving inline styles untouched.Is the translated EPUB compatible with Amazon Kindle, Apple Books, and Kobo?
Yes. The output passes standard EPUBCheck validation and can be uploaded directly to Amazon KDP, Kobo Writing Life, and Apple Books.
How do I prevent character names and fictional lore from being translated?
Add your character names, fictional places, and magic systems to your translation prompt (e.g. "Do not translate character names like Stoneheart").
Why not use Google Translate or ChatGPT to translate my ebook?
DeepL and ChatGPT cannot handle EPUB archives directly. Pasting raw text loses all chapter division, styling, internal links, and table of contents. Pasting raw HTML causes ChatGPT to truncate files or corrupt XML closing tags. AI Glot preserves the complete archive structure.
How does AI Glot handle the table of contents (TOC)?
Both EPUB 2 NCX and EPUB 3 Navigation documents are preserved. Chapter titles in the TOC are translated to match the chapter headings in the text, keeping internal links active.
What happens with text expansion in languages like German or French?
European languages are often 20% to 30% longer than English. Because EPUB is a reflowable format, e-readers automatically paginate the translated text without clipping or layout break.
Can I try translating an ebook for free?
Yes. Upload your .epub file into the free tool above to translate sample chapters or full manuscripts up to 25 000 tokens free of charge.
