You’ve done the hard work of writing a book. Could translating it help you reach a whole new audience?

For many independent authors, the idea is appealing, but the questions soon follow. How much will it cost? Can AI handle humour and character voice? And how can you judge a German or Italian translation if you don’t speak the language?

In a recent episode of The Publishing Performance Show, my wife Clare took over as interviewer to ask me about BookLingua, the AI-assisted book translation service I built for independent authors.

Clare is an author herself, so these were practical questions about translating and publishing her own books. What follows is an edited Q&A based on our conversation, rather than a verbatim transcript.

Why don’t more independent authors translate their books?

I think the biggest obstacle is cost.

Commissioning a professional translator for a full-length book can represent a substantial investment. Depending on the manuscript and service, that can run into thousands of dollars.

For an independent author, that’s a big commitment to a market where you may not have any readers yet.

You also have to think beyond translation. There’s the cover, the book’s sales page and the work of promoting it. If you have a whole series, those costs can quickly add up.

Working directly with a professional translator can be a good choice for authors who have the budget and want that close creative partnership. But many authors I speak to couldn’t consider translation at that price.

That’s the opportunity I wanted BookLingua to address: making it more affordable to test a book in another language. Our guide to book translation costs explains what to include when comparing different options.

How does BookLingua translate a book?

There’s preparation before the translation begins.

First, we ask you to complete a translation brief. This is where you tell us about your book and explain how you want particular details handled.

For example, you might want invented names to stay in English, a character to retain a particular speaking style, or romantic scenes to keep the same level of explicitness. Our translation brief guide explains what information is most useful.

We also use a cultural scan: an automated review that flags details which may need a translation decision. These might include expressions, measurements, references to schools or invented terminology.

Imagine your story is set in America and a character travels 20 miles. Should that remain in miles, or be expressed in kilometres? The right choice depends on the setting and your intentions.

The scan helps identify questions like these, although it shouldn’t be treated as an exhaustive list of every possible issue.

We identify the book’s structure, including its chapters, and use that structure and your instructions during translation. A separate AI editorial pass then reviews the translated writing and checks for issues such as inconsistent names, terminology or tone.

Can AI preserve romance, humour and character voice?

These are some of the hardest parts to get right.

You want a cheeky character to remain cheeky. You want a romantic scene to retain its atmosphere. A technically understandable translation can still miss those qualities.

That’s why the information you provide beforehand matters. The translation brief helps establish what we’re trying to preserve, and the editorial pass reviews the result with those choices in mind.

In the episode, we talked about how a poorly handled intimate scene can end up sounding like a medical textbook. The words might describe what’s happening, but the mood has disappeared.

Non-fiction has its own challenges. If you’re writing in a friendly, conversational voice, that should carry across. Some languages also make distinctions between formal and informal ways of addressing readers that English doesn’t express in the same way.

The aim is to preserve the experience of reading your book, as well as its meaning. That takes more attention than translating isolated blocks of text.

What does the professional translator review involve?

BookLingua packages come with a Targeted Professional Translator Review.

A professional translator reads selected passages where professional judgement is particularly useful. Depending on the book, these can include dialogue, humour, idioms, culturally specific references and emotionally important scenes.

They consider whether the language reads naturally, whether the writing is consistent and whether anything disrupts the reading experience.

This is an assessment of the translation. It isn’t a judgement about whether the reviewer personally likes your story or genre.

It also isn’t a full-manuscript proofread or line-by-line edit. That distinction is important when deciding whether you want to arrange additional review before publication.

How can I check a translation when I don’t speak the language?

Clare asked exactly this: if she translated her book into German but only knew basic German herself, how could she feel confident about it?

The targeted professional review provides feedback from someone who can assess the translated language. It sits alongside the AI editorial pass and consistency checks.

You can also commission an independent proofreader to review the full translated manuscript if you want that additional level of checking.

Knowing what has been reviewed—and how much of the book that covers—is more useful than relying on a general promise of quality.

Which language should I choose first?

It’s tempting to choose whichever language has the most speakers. But audience size is only one part of the decision.

In our conversation, I highlighted Italian and German as markets worth investigating, particularly for certain kinds of romance and non-fiction.

That doesn’t mean either language is automatically right for your book. You need to look at your genre, comparable titles and the readers you hope to reach.

Explore books similar to yours in that market. Look at how they’re presented, what they cost and what readers say about them.

Competition and advertising costs may also differ between markets. A smaller audience can still offer an opportunity, but cheaper advertising or strong sales should never be assumed.

The question is: where does your particular book have a promising fit?

Should I launch in more than one language?

You can, but it depends on your budget, experience and confidence.

Some of the work can be managed together. For example, you can oversee advertising campaigns for different Amazon marketplaces from the same advertising account.

But each edition still needs suitable publishing information and promotion. Translating into several languages creates more decisions and more spending to manage.

My advice is to test one language first. See how you find the process and what response you get before deciding whether to expand.

How does the Launch Strategy Pack help?

One of the questions authors kept asking was: “Once my book is translated, how do I market it?”

That led us to create the BookLingua Launch Strategy Pack, an optional paid add-on with materials and suggestions for publishing and promoting the translated edition.

It includes market-specific book-description copy, Amazon search keywords, advertising keywords, category suggestions, pricing guidance, researched promotional opportunities and a 30-day launch plan.

These need research in the language and market you’re publishing in. Simply translating your English keywords may miss the phrases readers actually use.

The pack gives you a practical starting point. You still make the publishing decisions and carry out the marketing, including checking that any suggested promotion opportunities remain suitable. For more detail, read our translated-book marketing guide.

The Launch Strategy Pack is priced separately from translation: $29 for one language or $49 when your order includes more than one language.

What should I prepare before submitting my book?

Send the version you’re happy to publish.

If you change the English manuscript after translation, those changes may also need to be made in the translated edition.

A Word document saved as a DOCX file is my preferred starting point. Clearly marked, consistent chapter headings help us identify the structure. BookLingua also accepts EPUB and TXT files.

We don’t accept PDFs for this process.

For your translation brief, gather any information that will help us understand your choices. If you write fantasy, that might include a glossary explaining invented names, places and spells, plus instructions about which terms should remain unchanged.

You don’t need translation expertise. You’re sharing the knowledge you already have as the author. Use our manuscript preparation guide before uploading your final file.

Where do professional translators fit alongside AI?

Clare asked whether services like BookLingua take work away from professional translators.

My view is that budget makes a significant difference. An author considering a translation costing thousands of dollars may have different needs and resources from someone testing a new language with a much smaller budget.

Working directly with a professional translator offers a different level of collaboration. For authors who want and can afford that relationship, it can be a valuable option.

BookLingua offers another route, while involving professional translators in targeted review. Authors should understand the scope of each service and choose the approach that suits their book and budget.

What’s your main advice to authors considering translation?

Start with a manageable test.

You’ve already invested time in writing your book. A translated edition gives you another way to offer it to readers—but it still needs appropriate presentation, promotion and a realistic budget.

Choose one language, understand the costs and decide how you’ll introduce the book to that audience. Then use what you learn to guide your next step.
