Translate a Book with AI is an online book translation service that uses a custom pipeline with the best AI models to translate your manuscript in minutes to hours while preserving layout, with free previews and no account required.
What is Translate a Book with AI?
Translate a Book with AI is a web-based service that takes your book file (PDF, DOCX, EPUB, IDML, MOBI, AZW3, HTML, TXT, and over 20 other formats) and produces a translated file in the same format with layout intact. It runs on a custom self-correcting pipeline using a blend of Google Gemini Pro 2.5, OpenAI GPT-5, and DeepSeek V3 models. The service is offered by the team at Translate a Book ([email protected]) and used by over 2,198+ happy authors.
Key Features
- Layout Preservation — Translates directly into the original file structure; font weights, images, footnotes, headings, tables, and links are preserved for all formats except PDF (where layout may change but text is extracted via advanced OCR).
- Three Quality Tiers — Standard mode (2–15€, a few minutes), Pro mode (4–40€, a few minutes), and Author mode (30–300€, a few hours) with increasing consistency and a translation guide.
- Translation Guide (Author Mode) — The AI reads your whole manuscript and drafts an editable guide covering characters, terminology, tone, and style preferences to ensure consistency across the book.
- Self-Review Loop — After translation, the system automatically fixes errors, inconsistencies, and awkward phrasing before delivering the file.
- Proofreading Report — Uses the academic MQM framework to score translation quality (e.g., 98.6/100) and surfaces each error with suggested corrections.
- Privacy & Security — No AI trains on your content; files are automatically deleted after 30 days (or 24 hours if not purchased). No account required to get a quote or free preview.
- Free Previews — Translate a portion of your book for free (Standard/Pro) or for 5€ (Author mode) before committing.
- No AI Training — The AI providers used do not log or train on your content; your manuscript stays yours.
Who is it for?
- Indie authors — Translate a self-published novel into multiple languages quickly and affordably to reach international readers.
- Academic researchers — Translate a thesis, dissertation, or scientific book while preserving complex formatting (tables, footnotes, references).
- Publishers — Produce draft translations of manuscripts for review without weeks of human translator turnaround.
- Non-fiction writers — Translate a how-to guide, memoir, or history book with consistent terminology and tone across hundreds of pages.
What can you do with Translate a Book with AI?
- Translate a novel to Spanish: Upload an EPUB, choose Standard mode, and get a readable translation in under 15 minutes with layout preserved.
- Translate a complex academic PDF: Use the advanced PDF analyzer (OCR for scanned pages) to extract text and rebuild the translation; perfect for multi-column, footnoted documents.
- Translate an InDesign file (IDML): Upload and receive a translated IDML where text is inserted in place, saving hours of manual layout work.
- Proofread a translation: After translation, run the built-in proofreading tool to get a detailed error report with MQM scores and suggested fixes.
How does it work?
- Upload your file (PDF, DOCX, EPUB, IDML, or other supported format) via the dropzone on the homepage. No account needed.
- Choose a translation mode (Standard, Pro, or Author). Author mode first analyzes your book and lets you edit a translation guide.
- Get a free preview of a portion of the translation (except Author mode, which costs 5€).
- Confirm and pay for the full translation. The system translates, self-reviews, and reconstructs the file.
- Download the translated file in the same format, with the original layout preserved.

Pros and cons
- Pros: No subscription; files are private and automatically deleted; layout preserved for all non-PDF formats; free previews; three quality tiers with different speeds; translation guide for consistency.
- Cons: PDF layout cannot be preserved (text is reflowed); Author mode takes several hours; AI translation may still require light proofreading (though built-in proofreading tool helps).
