How Do I Get My Self-Published Book Translated, and Does KDP Treat AI Translation Differently?

Book a free 25-minute call. Tell me where your book is now.

To get a self-published book translated, first check that KDP publishes in the target language, then choose between a human translator, Amazon’s Kindle Translate beta, or a translation made by an AI tool that a person edits. KDP treats the last two as AI-generated and asks you to tell it. A rights deal with a foreign publisher is a fourth route.

Which languages can I publish in on KDP?

KDP’s language help page lists the languages it supports. Check it before you pay anyone, because the ebook list is longer than the print list. Among the ebook languages are Spanish, French, German, Italian, Portuguese, Japanese, Hindi, Arabic, Hebrew and Norwegian. Polish and Ukrainian appear for paperback and hardcover but not for ebooks, and for print Japanese is paperback only. If your language is missing, you would need another store or distributor for it.

Does KDP treat AI translation differently?

Yes. KDP’s content guidelines say: “We require you to inform us of AI-generated content (text, images, or translations) when you publish a new book.” KDP defines AI-generated content as “text, images, or translations created by an AI-based tool,” and says it stays AI-generated “even if you applied substantial edits afterwards.” If readers are already saying your book reads as AI, read readers say my book is AI, what can I do?

So a machine translation that a person then polishes is still reported. What KDP does not ask you to report is AI-assisted work, such as a translator who wrote the text themselves and used a tool to check it. I go through the wording in KDP AI disclosure rules and do not repeat it here.

The same page has a rule for human translations: a book that translates another work “must credit the translator and the original author in the contributor field.”

Does the language setting matter?

Yes. KDP’s language page tells you to select the language in your Bookshelf that matches the written content, to prevent file rejection. So a Spanish translation is set up as a Spanish book, not as a version of the English one. It also notes that content in a language that is only available for ebooks can’t be turned into a paperback. If you want a print edition of the translation, check the print list first.

My book is in two languages. Which language do I choose?

KDP’s language page says that if your book includes multiple languages, you select the primary language. The language in your Bookshelf, the language the book is written in and the language in your file’s metadata must all match. Both languages also need to be on KDP’s supported list for the format you want. Arabic and Hindi are ebook only, while Ukrainian and Polish are paperback and hardcover only.

KDP’s content quality guide names facing-page translations, with one language on the left page and the same content in another on the right, among the books not suited to Kindle. They may be rejected or removed from sale. It also says text that shows in Kindle Previewer as jumbled characters or boxed question marks usually means an unsupported character.

My advice: choose the language most of the text is in, and make sure your file’s own language setting says the same. Publish a facing-page bilingual book as a paperback. For an ebook, check every page in Kindle Previewer before you upload.

What is Kindle Translate?

Kindle Translate is Amazon’s own AI translation tool for KDP ebooks, and it is in beta. Amazon’s announcement page (dated 6-Nov-25, updated 30-Jun-26) says it translates between English and Spanish, German, French, Italian and Portuguese, and is free for independent authors. You pick the languages, set the list price, and can preview the result or let it publish automatically. Translated titles are labeled as translations in the Amazon store, and they can go into KDP Select.

The page does not give a royalty rate, so check KDP before you rely on one. Because Kindle Translate is an AI tool, the translation is AI-generated under the rule above.

How do I publish the translated editions?

With Kindle Translate, KDP does the publishing, but only for eligible books. KDP’s eligibility page says the ebook must be live, reflowable and have a cover and a primary author or contributor. It can’t be a pre-order, public domain content or a book that is already a translation. KDP checks this after the ebook goes live, and the Translate option then appears on your Bookshelf. KDP’s getting started page says it creates the series for the translated titles within 5 business days of them going live. Only one translated edition per language can be available in the Kindle Store, and you can’t combine Kindle Translate ebooks with other translated ebooks in a series.

If you upload your own translation, it is a separate book in its own language. Set it up in a series in that language from Manage Series in your Bookshelf, using KDP’s series help.

Each upload also counts toward the KDP title limit: two new titles per format, reset every Sunday at 12:00 AM UTC. I found no KDP page that exempts translations, so ask KDP support before you plan a launch around one.

Does a translation need a new ISBN?

KDP’s ISBN page doesn’t mention translations. It says each format of a book, such as paperback and hardcover, needs its own ISBN, and that an ISBN can’t be reused for a new edition with significant changes from the original. It doesn’t say what counts as significant. A translation is a different text in a different language, so my advice is to give a print translation its own ISBN, and to ask KDP support if you are unsure.

Human translator, AI plus an editor, or a rights deal?

A human translator is the slowest route and the most work to manage. You hire the person, agree the fee and deadline in writing, and credit them on KDP. Rates vary a lot by language and by translator, so I am not going to quote one. Ask two or three translators for a sample page and a quote before you decide.

A machine translation with a human editor is cheaper in time. You still disclose it to KDP, and you still need a native reader to check names, jokes and anything specific to your subject. A translation that reads wrong in a language you do not speak is hard to spot yourself.

A rights deal means a publisher in the other country translates and sells the book. You give up control and part of the income, and you need a contract, so read are self-published books copyrighted first to see what you own.

If you are unsure whether a translation is worth doing before the next book, book a free discovery call and we can look at your title, your audience and which language is likely to repay the effort.
