Translate a Book with AI

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?

1. Upload your file (PDF, DOCX, EPUB, IDML, or other supported format) via the dropzone on the homepage. No account needed.
2. Choose a translation mode (Standard, Pro, or Author). Author mode first analyzes your book and lets you edit a translation guide.
3. Get a free preview of a portion of the translation (except Author mode, which costs 5€).
4. Confirm and pay for the full translation. The system translates, self-reviews, and reconstructs the file.
5. Download the translated file in the same format, with the original layout preserved.

Pricing

Translate a Book with AI uses a pay-per-use model with three tiers based on file length and language pair. Estimated ranges: Standard mode 2–15€, Pro mode 4–40€, Author mode 30–300€. Exact price is shown after upload. Free previews available for Standard and Pro modes.

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).
