This service is for authors who want their books automatically translated by one of the most advanced AI models in the world.

TranslateAI can translate your book from any language into up to 31 languages.

(Note that with the prices below, if you choose to translate a book which is over 200,000 words, there is an extra charge which will be shown below. However, almost all Leanpub books are shorter than that, so chances are this doesn't apply to you.)

When you buy a TranslateAI translation into 1 language for just $249, we give you TranslateAI translations into 2 additional languages for free!

TranslateAI is only $249 for 1-3 languages, $499 for 4-6 languages, $749 for 7-9 languages, $999 for 10-12 languages, and so on. Also, if you choose to translate into all 31 supported languages, we only charge you $2499 -- we include the 31st language for free as well.

(TranslateAI is $249 for the first group of 3 languages. If you want to translate into more than 3 languages, it's just $250 for each additional group of 3 languages. The reason that it's $250 instead of $249 is that we want to keep the pricing ending in 9, because it looks nicer!)

Regardless of how many languages you choose, this is a great deal! Since we pay 80% royalties, if you sell just a handful of copies of your book in each language, you'll already be ahead...

TranslateAI translations for all 31 supported languages are also included in all of our amazing GlobalAuthor bundles, which also include creating an index with IndexAI, creating a course with CourseAI, and publishing on Amazon if you buy GlobalAuthor Pro or Max.

The TranslateAI service is fully automated, and typically takes under 4 hours per language chosen.

Due to the nature of the service, we can't guarantee a specific turnaround time. However, if you don't get an automated email within one business day, please email hello@leanpub.com and we'll look into it for you.

To see the output of TranslateAI right now, you can check out How To Be a Modern Scientist and The Elements of Data Analytic Style by bestselling Leanpub author Jeffrey Leek. You can also check out Lean Publishing by Leanpub Founder Peter Armstrong, which has been translated into 31 languages with the GlobalAuthor Pro bundle.

All three of these books have been translated into 31 languages using our TranslateAI service for non-fiction authors! Scroll down on the books' landing pages to see the translations. All three of these books and all their translations have a free minimum price, so feel free to buy it for free in both the English language version and in one or more translations if you want to see what TranslateAI can do.

For another example of TranslateAI, you can also check out Cloud Strategy by bestselling Leanpub author Gregor Hohpe. This book has been translated into 29 of the 31 languages in GlobalAuthor using TranslateAI. (We skipped Japanese and Korean, since Gregor already had translations for those.) Note that Cloud Strategy and its translations have a paid minimum price, so to review the output of those, you'll need to buy them!

Yes. You own your TranslateAI translations, both those purchased individually or as part of a GlobalAuthor bundle.

You can sell your TranslateAI translations anywhere that allows AI translations to be sold as ebooks or print books. (This currently includes Amazon KDP, but we obviously don't control Amazon's policies about AI translations.)

You do not need to give Leanpub any of your money from sales on other platforms, either of your translation or your original book. You own your work, and you own your AI translations too.

We built TranslateAI for one obvious reason: the more languages your book is available in, the more readers you can reach.

Leanpub exists to serve our authors. We want to help you reach as many readers as possible, and we want to help you make as much money as possible. We also want to help you save time, so you can spend more time writing and less time doing other things.

Now, the best way for readers to read your book is in their preferred language. This is their first language: what they grew up speaking, and what they are most comfortable reading in.

For our authors who write in English: just because many people in the world can read English as a second language to some extent doesn't mean they should have to read your book that way. Furthermore, billions of people cannot read English, even as a second language. If you want to reach these people, you need to translate your book into their language. First and foremost, this is a question of accessibility: if your readers cannot read your book, it does not matter how good it is.

For our authors who write in a language other than English: TranslateAI is even more valuable for you, especially if you're writing a computer programming book or business book. English is the largest market for these books, and you're really missing out by not having an English version of your book!

So, just as Leanpub automates the process of creating a PDF and EPUB ebook from your book manuscript, and automates the process of producing a print-ready PDF, we also wanted to automate the process of translating your book into other languages.

We've always tried to give our authors even more than what they get from a traditional publisher: a better royalty rate, more royalties overall, more control, more flexibility, etc. Now, with TranslateAI, we can even give you more translations!

We've worked very hard on TranslateAI, spending months tuning it and testing it, and we're very happy with the results. We hope you will be too!

The TranslateAI service uses Claude Sonnet 3.5 v2 or GPT-4o for great quality AI translations.

We use Claude Sonnet 3.5 v2 or GPT-4o via one of their APIs, to automatically translate your book. The specific model we use is chosen on a per-language basis, based on our internal testing. We also automatically validate the translation to ensure that everything was translated, except for code samples and images which are preserved unchanged.

TranslateAI works with books written in Markua 0.30, Markua 0.10 or Leanpub Flavoured Markdown (LFM).

If you're not happy with the results, or if your book is not a good fit for the service, we'll fully refund your money.

Yes, our 60 Day 100% Happiness Guarantee applies here, just like it does with all Leanpub purchases!

Now, this is technically risky for us, since you'll have the translated manuscript either way. But we're so confident in our services and in our authors that we're happy to offer our full money back guarantee for all our services.

You can only find out how good the service is by trying it, and because of our 100% money back guarantee there's literally no risk to do so!

So, there's no reason not to try the service, is there?
