Frequently asked questions
Is the translation as good as a human translation?
No, and we do not claim it is. A great literary translator is still better. But the chain we use — style sheet, passage-by-passage translation, review by independent agents, arbitration, automatic checks — produces a text that is faithful, consistent and pleasant to read, for a fraction of the price. For a book that would otherwise never be translated, it is the difference between existing in a language or not.
How long does it take?
24 to 72 hours in general, depending on the length of the book and the number of languages. All our translations run in deferred processing, which lets us keep prices low. You follow every step online.
Which formats do you accept?
DOCX (Word), ODT (LibreOffice), EPUB, Markdown and plain text. No PDF: a PDF has lost the structure of its paragraphs. Export the source file from your word processor.
Is my manuscript used to train an AI?
No. Your text is sent to our model provider through its professional interface, which does not train its models on this data. We neither publish nor resell it, and we delete your files 90 days after delivery.
Do I have to disclose AI on KDP?
Yes. Amazon asks you to declare AI-generated content in the “Content” tab of your book — an AI-produced translation counts, even if you review it afterward. It is a declaration to Amazon, and it is not shown to readers.
An 80,000-word novel costs €480 at the Quality level, review and arbitration included.
