Founder-led publishing experience
Built by someone who understands authors
BookLingua was founded by Teddy Smith, an author, publishing marketer and host of The Publishing Performance Show. Through the romance book-discovery newsletter My Romance Reads, he has also built an audience of more than 18,000 romance readers and helped independent authors promote their books.
Teddy created BookLingua to give authors a faster, more affordable way to reach international readers—without losing the voice and personality that made their books worth translating in the first place.
What You Get Back
Your translated files, AI editorial highlights and native-speaker proofreading report
If you upload EPUB
Your translated EPUB will look great and read naturally - in the clean, standard ebook style readers are used to. Chapter structure and paragraphs are preserved.
If your original has custom styling (special fonts, drop caps, complex layouts), you'll want to review and apply those in your formatting tool before publishing. Many authors go straight from BookLingua to KDP upload.
If you upload DOCX
We do our best to keep your original formatting - fonts, spacing, headings, bold and italic text - so your translated file looks as close to the original as possible.
Most customers can go straight from BookLingua to KDP or print setup, but it's worth a quick review to make sure you're fully happy before going to print.

Frequently Asked Questions
Everything you need to know before you get started
Is this better than Google Translate?
Yes - significantly. BookLingua uses a specialist AI translation pass followed by a separate AI editorial-review stage that refines idioms, adapts cultural context, and improves natural phrasing. Every AI editorial change is highlighted so you stay in control. A native-speaker proofreader then carries out an independent human quality check and provides a report.
What file formats do you support?
EPUB, DOCX, and TXT. We recommend DOCX for best results - it gives the most accurate word count and preserves formatting perfectly. PDF is not supported as formatting is lost during conversion.
How long does translation take?
Most books complete within 2-6 hours depending on length. You'll receive an email with your download link as soon as it's ready.
Can I see examples before I buy?
Absolutely - visit our Examples page to see real side-by-side translations with editorial highlights.
View Examples →What if I'm not happy with the translation?
Email us within 7 days and we'll work with you to make it right.
Do you offer pricing for publishers with larger catalogues?
Yes - if you have 10 or more books, we offer custom bulk pricing and a hands-off pipeline.
Learn more →How much does AI book translation cost?
Our pricing is based on word count: $99 for up to 40k words, $149 for up to 80k words, and $199 for up to 150k words — per language. If you translate into multiple languages, bundle discounts apply automatically, up to 20% off when you translate into 6 or more languages.
Is AI book translation good enough to publish?
It can be — with the right process. BookLingua combines a cultural scan, AI translation, a separate AI editorial-review pass, consistency checks, and an included native-speaker proofreading report. The human proofreader assesses how the translation reads rather than rewriting every sentence.
What languages can I translate my book into?
We currently support Spanish (Spain), Spanish (Latin America), French, German, Italian, Portuguese (Portugal), Portuguese (Brazil), Polish, and Japanese.
Can AI translate fiction and keep my author voice?
Yes. We use genre-specific prompts and a translation brief to preserve your tone, style, character voices, and narrative pacing. The AI editorial-review stage then refines idioms, dialogue, and cultural references, before a native-speaker proofreader provides an independent assessment.
Will my manuscript formatting be preserved?
DOCX gives the best formatting preservation. EPUB comes back ebook-ready. TXT is supported for plain text. PDF is not supported because formatting is lost during conversion.
Is every translation checked by a human?
Yes. After BookLingua completes its translation and AI editorial-review stages, a native-speaker proofreader carries out an independent quality check. You receive their report alongside your translated files, so you can see how the book reads to a real person in the target language.
Can I translate my whole book series?
Yes. We build a shared glossary and style guide so character names, invented terms, place names, and voice stay consistent across every book in the series.
