Book Translation Software for Authors
Translate a full manuscript with AI in 204 languages, keep every character name consistent with a glossary, and revise the draft in the built-in editor. One novelist did 63,000 words in a month for $99.
Can AI translate a whole book?
Yes. AI translates a full-length book into a first draft good enough that most of it goes straight into the manuscript, and the rest is small, findable edits. Taia is book translation software built for exactly that: whole manuscripts rather than pasted paragraphs, a glossary that holds character names steady across every chapter, and a built-in editor so you revise the draft where it lands.
Taia is an AI-first localization platform that combines instant AI translation in 204 languages and 65+ file formats, a built-in CAT editor and translation management system (TMS), and ISO 17100-certified professional linguists, with translation memory, glossary, and style guide shared across all three.
What AI does not do is save you the reading. Nobody can tell you which six percent of a translation needs changing until someone has read one hundred percent of it. A good AI translation gives you a first draft worth reading and far less to fix by the end.
A 63,000-Word Novel into English for $99
Carole Sainte-Marie is a French-Canadian novelist. She translated Dernier jour au paradis from French into English with Taia in one month, chapter by chapter, and read every line of what came back.
"Taia was superior. Some sentences were exactly the same, but in a book you also have to transmit the emotion, the feeling. And honestly, Taia was a little better than DeepL."

Every Kind of Book, Chapter by Chapter
Taia treats a book as one project rather than a stack of unrelated files, so terminology and style carry across the whole manuscript.
Novels & Literary Fiction
Full-length fiction where voice, register, and invented vocabulary have to survive the translation
Non-Fiction & Memoir
Narrative non-fiction, memoir, and essay collections translated with consistent terminology throughout
Self-Published Books
Independent authors publishing their own editions, without a publisher or a localization budget
Children's & YA
Shorter books where names, rhyme, and reading level need a human pass after the AI draft
Textbooks & Academic Work
Long-form academic and educational texts where defined terms must stay identical across chapters
Business & Technical Books
Professional titles with domain vocabulary, handled by glossary and translation memory
From Manuscript to Translated Draft
Four steps, repeated per chapter or run across the whole book. No technical setup and nothing to integrate.
Upload a Chapter or the Whole Manuscript
Drop in DOCX, PDF, or any of 65+ formats. Work chapter by chapter or all at once.
Attach Your Glossary
Add character names, place names, and invented terms so they come back the same way in every chapter.
Translate with AI
AI translates into any of 204 languages, guided by your translation memory, glossary, and style guide.
Revise in the Editor
Read the draft and fix what needs fixing in the built-in CAT editor, without leaving the platform.
A Book Is Not a Long Document
Book-length translation fails in specific, predictable ways. These are the three that matter most, and what fixes each one.
Names have to hold across 300 pages
A character or place name translated three different ways across three chapters breaks the book. Attach a glossary to the project and those terms come back identically every time. Carole kept the French name of a jeweller's shop and the Indonesian vocabulary in her Bali chapters exactly this way.
Some words should not be translated at all
Foreign words used deliberately, invented vocabulary, and proper nouns you want left in the source language are exactly what a general-purpose engine will "helpfully" convert. The glossary is what tells it not to.
You need to edit where the text lives
Exporting a draft, editing it elsewhere, and reimporting it is where book projects fall apart. Taia's built-in CAT editor lets you revise the translation in the same place it was produced, chapter by chapter.
Someone has to read the whole thing
AI translation is not 100%, and we say so before anyone buys. Whether that reader is you, your own editor, or an ISO 17100-certified linguist from Taia, a book gets read end to end before it ships.
AI Draft, Professional Review, or Both
Most independent authors run AI and edit themselves. Publishers and authors without the target language add professional review on top.
AI translation, edited by you
Right when you read the target language well enough to judge the prose. You get the whole book for the price of a subscription and do the editing pass yourself.
- Subscription pricing, not per word
- Translation memory, glossary, and style guide guide the output
- Revise in the built-in CAT editor as you go
Professional linguists on top
Right when you do not read the target language, or the edition is going to a publisher. Professional services are always pay-per-use, never subscription.
- Essential: one linguist, from €0.06/word
- Enhanced: translator plus revisor, ISO 17100, from €0.09/word
- Ultimate: full translation, editing, proofreading, from €0.12/word
What Translating a Book Actually Costs
AI translation is priced by monthly subscription, so a longer book does not automatically mean a bigger bill.
Typical Book Lengths
- Children's picture book 500-2,000 words
- Novella 20,000-40,000 words
- Business / non-fiction title 40,000-60,000 words
- Standard novel 60,000-90,000 words
- Epic / literary fiction 100,000+ words
Carole's novel was 63,000 words across 27 chapters, translated inside one month.

Looking for a DeepL alternative for full books?
Taia is built for full-document translation where DeepL is built primarily for shorter text, and over a book-length manuscript that difference compounds. Taia translates entire files in 65+ formats with formatting preserved, keeps your glossary and translation memory attached across every chapter, and gives you a built-in editor to revise in place.
Carole Sainte-Marie translated her first chapter in both tools before she chose. Her search was, almost word for word, "best DeepL alternative."
Frequently Asked Questions
What is the best book translation software?
The best book translation software handles a whole manuscript rather than a paragraph at a time, keeps character names and invented terms consistent across every chapter, and lets you edit the result without exporting it somewhere else. Taia does all three: upload a chapter or a full manuscript, translate it with AI in 204 languages, attach a glossary so names come back the way you want them, and revise the output in the built-in editor. Novelist Carole Sainte-Marie translated a 63,000-word novel from French into English this way in one month.
Can AI translate an entire book?
Yes. AI translates a full-length book quickly and accurately enough to serve as a strong first draft, but it is not a finished edition on its own. When Carole Sainte-Marie translated her 63,000-word novel with Taia, 94% of segments went into the manuscript exactly as the AI delivered them and she revised the remaining six percent herself. The reading still has to happen, because nobody can tell you which six percent needs changing until someone has read all of it.
Is there a free AI book translator?
Taia is free for the first 5,000 words a month, which is enough to translate a sample chapter and judge the quality before you pay anything. A full-length book runs past that: a 63,000-word novel needs a paid month. Paid plans start at €9/month for 20,000 words (Basic) and €39/month for 100,000 words (Pro), which adds Translation Memory, Glossary, and Style Guide. Start at translate.taia.io and translate a chapter free first.
How much does it cost to translate a book?
With AI translation, a full book costs the price of a monthly subscription rather than a per-word fee. Carole Sainte-Marie translated her whole 63,000-word English edition inside a single month at $99. If you want professional linguists instead of AI alone, Taia's pay-per-use tiers run from €0.06/word (Essential, one linguist), €0.09/word (Enhanced, translator plus revisor, ISO 17100-certified), and €0.12/word (Ultimate, full translation-editing-proofreading). For a 63,000-word novel, professional translation is a different order of cost from AI, which is why most independent authors run AI first and edit themselves.
What is the best DeepL alternative for translating full books?
Taia is built for full-document translation where DeepL is built primarily for shorter text, which is the difference that matters over a book-length manuscript. Taia translates entire files in 65+ formats with formatting preserved, keeps a glossary and translation memory attached across every chapter of the project, and gives you a built-in editor to revise the output in place. Carole Sainte-Marie translated her first chapter in both tools and chose Taia. See our full Taia vs. DeepL comparison for a feature-by-feature breakdown.
Can I use Google Translate to read a book in another language?
Google Translate is fine for reading a book to understand it and useless for publishing one. It gives you the gist page by page, with no way to keep character names consistent, no formatting preserved across a long manuscript, and no editor to fix what it got wrong. If you want to read, any free tool will do. If you want an edition other people will read, you need software that treats the book as one project, which is what Taia does.
How do I keep character names and invented terms consistent across chapters?
Attach a glossary to the project and the engine returns those terms the same way every time. This is the single most useful feature for fiction, because novels are full of words a translation engine should leave alone: character and place names, invented vocabulary, foreign words used deliberately. Carole Sainte-Marie kept the French name of a jeweller's shop and the Indonesian vocabulary running through her Bali chapters by putting them in a glossary and attaching it to every chapter project.
Do I still need a human editor after AI translation?
Yes, and we say so before anyone buys. AI translation is not 100%, and a book needs someone who reads the target language to go over the whole thing. Typical fixes are small and specific: a gendered adjective attached to the wrong speaker, straight quotation marks where literature wants curly ones. You can do this yourself if you read the language, hire your own editor, or add ISO 17100-certified professional review from Taia on top of the AI draft.
