Frequently Asked Questions

AI models have become really good at handling text, so your translation should be really good too! This is still automated translation and the AI might sometimes make mistakes, but the technology has become really impressive.

We use DeepSeek V3, one of the most cutting-edge AI models in the world. DeepSeek released their model as open source and made the world headlines after reaching performance on par or better than models of giant companies with much fewer resources.

We also don't just pass your text to the AI model: we do a significant number of custom improvements tailored for translating books so you get the best possible result. We're always improving our tool based on feedback from users and the evolving underlying technology.

The translation time depends on your document length. In the first two translation modes most books are translated in less than 10 minutes, sometimes up to 20 minutes. Author Mode analyzes your book before translating it step by step, which can take from 3 to 12 hours.
Unfortunately, since our AI takes uses resources to produce your translation, we can't guarantee refunds for reasons other than technical difficulties (we do guarantee you'll have a working translated file, of course). We recommend doing a free preview if you're unsure about the result.

Yes! When translating your book with our tool you'll get a file in the same format as the one you uploaded, and unless specified otherwise all formatting will be preserved. This includes images, tables, links, and other typographic elements. If for some reason your file format is complex and the layout will change, we will warn you beforehand.

You'll get a beautiful book in the language of your choice in just a few minutes.

The price depends on the length of your book, the file format, the language and the structure of your file. You should upload your book to get a quote (uploaded files are automatically deleted within 24 hours if you don't purchase a translation).

We are always adding more supported formats. EPUB work especially well, and we support DOCX, HTML, IDML and TXT natively as well. PDF files are notoriously difficult to handle - we provide ample previews to help you get a sense of what the result will look like, if you don't have the original file that was used to create the PDF and have to use it.

The full list of currently supported formats is: AZW3, DOC, DOCX, EPUB, FB2, FDX, HTM, HTML, HTMLZ, IDML, MOBI, ODT, PAGES, PDF, PRC, RTF, TXT

We're regularly improving this tool - if you need a specific file extension supported, let us know!

Your data is only used to provide you with this service or reach out to you regarding your translation.

Your email is only used to send you your translation or ask for feedback.

If you upload a file without ordering a translation, it will be deleted automatically from our server after 24h. All other uploaded files and translations are automatically deleted after a month (previews, after a week). You can ask for them to be deleted at any moment before.

To run our chosen AI model we route parts of your file to providers that run the actual model for us; we only use providers that do not log the content of what's shared with them and do not train any AI model with it.

You can check the privacy policy for the full detail on all of this.

With our tool you can upload a book in any format and translate it with a cutting-edge AI that understands nuance and preserves formatting, giving you a beautiful and professional-looking result in a just few minutes.

We're proud to use an advanced AI model that supports dozens of languages and allows us to get a fluent result. You can tweak how we use the AI by switching translation modes. The system can handle files large and small, and most common file formats are supported (DOCX, EPUB, PDF, MOBI, AZW3, HTML, TXT...)

It doesn't require creating an account: the app is very simple to use and notifies you when it's done. Just upload a file and click translate!
