Question 7

How is BookTranslate.ai different from just using ChatGPT?

Accepted Answer

Comparing BookTranslate.ai to a general-purpose AI like ChatGPT is like comparing a professional film studio to a phone camera. Both can create images, but only one is engineered for a professional masterpiece.

ChatGPT gives you a single, stateless translation, which might be inconsistent, full of hallucinations and meaning drift. BookTranslate.ai provides a complete, end-to-end literary translation ecosystem.

Here's what our system does that a general AI cannot:

Deep Literary Analysis: Before translating, our Preprocessor reads the entire book to understand its themes and authorial voice, creating a custom blueprint for the translation.
The AI Editorial Council: You can summon a panel of world-class AI models (Gemini, Claude, GPT-4o) to debate stylistic changes, ensuring accountability and preventing a single AI's bias from harming the text.
The Threadweaver: Our coherence engine performs a book-wide audit to guarantee that key terms and themes are translated consistently from Chapter 1 to Chapter 20—a feat impossible for a chat-based AI.
Structured Workflow: Our system includes a multi-pass refiner, a fidelity-auditing Finalizer, collaborator roles, and full contextual review tools. It's not a chat window; it's a professional-grade production environment.

Using ChatGPT for a book is a gamble. Using BookTranslate.ai is a professional, auditable process designed to honor the author's work with unwavering fidelity.

Question 8

What is the "AI Literary Analysis Engine" or "Translation Blueprint" feature?

Accepted Answer

Before translating your book, BookTranslate.ai employs a unique AI Literary Analysis Engine. This advanced system reads and analyzes your entire manuscript to identify key literary elements such as themes, authorial style, character voices, narrative structure, pacing, tone shifts, and even subtle techniques like foreshadowing. Based on this deep understanding, it generates a custom "Translation Blueprint" - a set of tailored global and section-specific instructions, plus a suggested glossary - that guides our translation AI to produce a version that is not only accurate but also deeply faithful to the unique spirit and nuances of your specific book.

Question 9

How does the AI Literary Analysis improve my book's translation quality?

Accepted Answer

The Translation Blueprint created by our analysis engine provides highly contextual and specific guidance to our translation AI for every paragraph. Instead of just general translation rules, the AI receives dynamic instructions on how to handle, for example, a specific character's dialogue in a particular chapter, or how to render the tone during a crucial plot point, or how to ensure consistency for a recurring symbol. This leads to translations with superior contextual accuracy, consistent character voices, appropriate tonal shifts, and a much richer reflection of your original literary intent.

Question 10

Do I need to do anything to activate or use the AI Literary Analysis?

Accepted Answer

No, this advanced analysis is a standard part of our translation process for every book you submit to BookTranslate.ai. You can run it with a single click after you upload your manuscript and before the first translation pass begins. You benefit from its insights without any extra steps. You can view the generated analysis (global guidance, section-specific instructions, and suggested glossary) in your project dashboard once it's complete.

Question 11

Can I see the "Translation Blueprint" or the analysis results for my book?

Accepted Answer

Yes! Once the AI Literary Analysis is complete for your project (this usually takes just a few minutes after running it, depending on book length), you can access and review the full "Translation Blueprint" within your project details on the dashboard. This includes the overall book guidance, the section-specific instructions with their context, and the AI-suggested glossary terms. We believe in transparency and want you to see the depth of understanding our AI brings to your work.

Question 12

Can I edit or provide input into the AI-generated Translation Blueprint?

Accepted Answer

No, the AI Literary Analysis generates the initial blueprint automatically based on its comprehensive reading. While you cannot directly edit the AI-generated instructions within the system before translation, you can significantly influence the process:

Use the "Custom Instructions" field during book upload to provide your own overarching guidelines, which the AI will consider alongside its own analysis.
Review and manage the AI-suggested glossary, and add your own terms to create the definitive project glossary that will be strictly enforced.
After the translation passes, you can use the insights from the AI analysis to guide any manual review or editing you choose to do, as you'll have a clear understanding of the stylistic and thematic intentions for each section.

Question 13

How does this AI Analysis differ from just using good general translation prompts?

Accepted Answer

While our core translation AI already uses sophisticated general prompts and weights for quality, the AI Literary Analysis provides an additional layer of book-specific intelligence. Instead of just telling the AI "translate fiction well," it provides dynamic, targeted instructions like, "For this specific chapter of your book, which focuses on the protagonist's internal conflict, the tone should be X, and the narrative voice should emphasize Y by doing Z." This deep customization for each individual book, based on a full-manuscript reading, is what sets our process apart and leads to more authentic and nuanced results beyond what general prompting alone can achieve.

Question 14

Does the AI Literary Analysis work differently for fiction versus non-fiction?

Accepted Answer

Yes. When you mark your book as 'fiction' or 'non-fiction' during upload, our AI Literary Analysis Engine applies a genre-specific analytical lens. For fiction, it focuses more on elements like character arcs, narrative voice, plot structure, symbolism, and foreshadowing. For non-fiction, it prioritizes argumentative structure, logical cohesion, authorial stance, and precision of terminology. This ensures the generated 'Translation Blueprint' is highly relevant to the specific type of your book.

Question 15

How does the multi-pass system work at a high level?

Accepted Answer

It's an iterative editorial process. The AI first creates a high-fidelity translation, then subsequent passes refine it. Early passes focus on fluency and correcting obvious errors. Later passes (4-5) use more sophisticated instructions and an internal, multi-agent review system to tackle nuanced issues of style, tone, and authorial voice. It's designed to build quality in layers, from a solid foundation to a polished final product.

Question 16

What happens in the advanced refinement passes (4 and 5)?

Accepted Answer

This is where our system's true power activates. The AI is guided by stricter, more nuanced instructions. For certain paragraphs, it automatically triggers an internal 'Finalizer' audit to find subtle flaws. If an issue is found, a 'Fixer' persona generates a revision, which is then submitted to an internal AI Council for a vote. This recursive feedback loop ensures that any change in the final stages is a verified, high-confidence improvement.

Question 17

Can the AI truly replicate an author's unique writing style?

Accepted Answer

Yes, this is a core design principle. The system is guided by the AI Literary Analysis performed at the start, which creates a 'Stylistic Fingerprint' for your author. The later passes are explicitly instructed to preserve this unique voice—whether it's formal, archaic, or stylistically complex. The AI actively avoids 'normalizing' a distinctive style, aiming to create a translation that embodies the original's specific flavor and rhythm.

Question 18

Why do some paragraphs not change in later passes?

Accepted Answer

That's a sign of success. The later passes are intentionally conservative. If a paragraph is already fluent, accurate, and aligned with the author's voice, the system leaves it untouched to prevent over-editing or regressions. The goal is quality and stability, not change for its own sake.

Question 19

So what's the point of 5 passes if not everything changes?

Accepted Answer

The value is in aggregate quality across a full book. Even if only 1 in 10 paragraphs is improved in the final passes, that can mean hundreds of crucial fixes in a manuscript—a smoother phrase, a more precise term, or a subtle error caught. The 5-pass system isn’t about changing everything; it’s about having a rigorous process to find and polish what needs attention, which is the difference between a 'good' draft and a 'publish-ready' one.

Question 20

How does the system handle specialized or niche subject matter?

Accepted Answer

It performs exceptionally well because it combines two approaches. First, the AI's broad knowledge allows it to understand context in specialized fields. Second, our AI-suggested and user-defined glossary feature allows you to enforce perfect consistency for your most critical, niche terminology. This combination ensures both contextual understanding and terminological precision.

Question 21

Are different AI models used for different passes?

Accepted Answer

All passes are orchestrated by our proprietary system, but they are powered by different prompt strategies, not different models. Each pass gives the AI a new, more demanding role—from a basic translator to a senior literary editor. This layered, role-based approach allows a single, powerful AI to perform a sequence of increasingly sophisticated tasks.

Question 22

What technology is this built on?

Accepted Answer

Our platform is model-agnostic, using a custom orchestration layer to leverage world-class AI models from providers like Google, Anthropic, and OpenAI. The real 'secret sauce' is not any single model, but our proprietary system of layered prompts, multi-agent workflows, and the recursive self-correction loops built into the later passes. This architecture allows us to produce results that consistently surpass what any single model can achieve on its own.

Question 23

What is the "Finalizer" or AI Final Review Engine in BookTranslate.ai?

Accepted Answer

The Finalizer is your personal, on-demand quality assurance engine. While our advanced refinement passes (4 and 5) have their own internal finalizer logic, you can run this module as a separate, final step. It gives you a complete, paragraph-by-paragraph audit of your translation against the original, acting as an expert AI "second opinion" to catch any remaining subtle issues and give you maximum publishing confidence.

Question 24

Why would I need the Finalizer if the 5-pass system is already ~98% publishable?

Accepted Answer

That's a great question! Our 5-pass system is indeed designed to produce exceptionally high-quality, near-publishable translations. The Finalizer isn't about fixing major flaws from that system; it's about striving for an even higher level of refinement and confidence.

It helps by:

Catching ultra-subtle nuances: Issues that might be almost imperceptible but could elevate the text further (e.g., the perfect idiomatic expression, slight tonal shifts, optimal word choice for specific authorial voice).
Providing a different "critical lens": The Finalizer is prompted differently than the translation/proofreading passes. It looks at the already polished translation with a specific mandate to find "publication-relevant" discrepancies against the original, sometimes highlighting things that the iterative self-improvement of the 5 passes might have stabilized.
Reinforcing consistency: It can act as a final check on critical elements like glossary adherence or the consistent application of global stylistic instructions across the entire book.
Building maximum confidence: For authors and publishers who want the utmost assurance in their translated work, the Finalizer offers an additional layer of AI-driven scrutiny.

Question 25

Does using the Finalizer mean my initial 5-pass translation was bad or erroneous?

Accepted Answer

Not at all. The Finalizer is designed to work on translations that are already very good. If the 5-pass translation were full of basic errors, the Finalizer's feedback would be overwhelming and less useful for fine-tuning. The fact that the Finalizer often identifies very nuanced points (like those seen in our Lovecraft or Böhm-Bawerk review examples) in a 5-pass translation is a testament to the quality of both systems: one for excellent generation, and one for highly detailed critique. It’s about taking something from 98% to potentially 99.x% in terms of polish and fidelity.

Question 26

What kind of issues does the Finalizer typically identify?

Accepted Answer

The Finalizer is prompted to focus on "publication-relevant" issues and to ignore minor stylistic preferences or nitpicks. It typically looks for:

Mistranslations: Subtle inaccuracies in meaning, lost information not caught earlier, or slight logical disconnects.
Awkward/Unnatural Phrasing: Sentences or phrases that, while perhaps grammatically correct, might subtly disrupt the reading flow or sound slightly "off" to native speakers in the target language.
Loss/Distortion of Tone & Style: Instances where the authorial voice or intended atmosphere might be slightly diminished or altered.
Critical Omissions/Additions: Significant missing or added words/clauses that impact meaning, or major structural discrepancies (like incorrect paragraphing of key elements).
Consistency Issues: Checks against established glossary terms or global instructions.

Question 27

How does the Finalizer process work technically?

Accepted Answer

The Finalizer uses the same advanced AI model family as our other core processes. It takes your original manuscript and the final (Pass 5) translation as input. These are typically processed in manageable chunks for efficiency. The AI is then guided by a specialized prompt that instructs it to perform a comparative review, identify specific types of issues, and return its findings in a structured format (detailing the paragraph, issue, and often a suggested fix and severity).

Question 28

What’s the difference between the Finalizer and the earlier proofreading passes?

Accepted Answer

Earlier passes are iterative self-improvements where the translation is refined based on prior outputs and structured instructions. They’re primarily inward-facing.

The Finalizer is a comparative QA step. It reviews the final output against the original source text, paragraph by paragraph, with a mandate to flag any remaining fidelity issues, idiomatic weaknesses, or glossary/style mismatches. It's not improving by rewriting — it's auditing for correctness, clarity, and polish from a critical distance.

Question 29

Are the Finalizer's suggestions automatically applied to my translation?

Accepted Answer

No, absolutely not. The Finalizer provides suggestions for your review. You will receive a report or be able to see these suggestions alongside your text. You always retain full control over your translation. The Finalizer’s suggestions are meant to assist your judgment - not to overwrite it. You can preview, apply, edit, or ignore each issue individually.

Question 30

When should I consider using the Finalizer?

Accepted Answer

The Finalizer is most beneficial when:

You are aiming for the absolute highest standard of literary or academic quality.
Your book is highly nuanced, stylistically complex, or contains very specific terminology.
You want an extra layer of AI-driven scrutiny to catch anything that might have been missed before publishing.
You appreciate detailed feedback that can help you understand potential areas of refinement in your translation.

It's an optional step for those who want to go the extra mile in perfecting their translated work.

Question 31

Will the Finalizer find issues in every book?

Accepted Answer

Not necessarily. If your 5-pass translation is already exceptionally clean and faithful for a given text, the Finalizer might return very few suggestions, or even none. This would be a strong indicator of the initial translation's quality. However, for complex literary or academic works, its keen "eye" often finds subtle points that can further enhance the text. The goal is to provide valuable insights where they exist.

Question 32

What is the difference between the Finalizer and the Naturalizer?

Accepted Answer

They have opposite missions. The Finalizer is a meticulous proofreader, hunting for objective errors to ensure foundational fidelity to the original text.

The Naturalizer is a master literary stylist. It assumes the translation is already accurate and suggests subjective, artistic improvements to rhythm and flow. The Finalizer ensures the translation is correct; the Naturalizer aims to make it compelling.

Question 33

Why do I need to approve every Naturalizer suggestion individually?

Accepted Answer

Because stylistic changes are a matter of taste and carry risk. The Naturalizer explores every possibility to elevate the prose, but some suggestions might subtly alter the author's voice. We call this 'creative temptation.' There is no 'mass auto-apply' because you are the final steward of the author's legacy. Your judgment is essential, so every change is your call.

Question 34

What is the AI Editorial Council?

Accepted Answer

For any Naturalizer suggestion you are unsure about, you can summon the AI Editorial Council. This is our ultimate accountability feature. A panel of world-class AI models (Gemini, Claude, GPT-4o) will independently review the proposed change, providing a transparent "verdict" and justification. You see the full debate—the different AI perspectives on the stylistic trade-off—and then make the final call.

Question 35

What is the Threadweaver?

Accepted Answer

The Threadweaver is the final, book-wide mastering pass. It is an AI coherence engine designed to solve a problem that is fundamentally impossible for human teams to manage at scale: long-form consistency. It protects the structural integrity of your entire book, ensuring the author's vision remains intact from the first page to the last.

Question 36

How does the Threadweaver work?

Accepted Answer

It operates in two main phases:

Blueprint Phase: It first performs a deep, multi-pass scan of your manuscript (Lexical, Semantic, Relational) to create a CoherenceLedger—a map of your book's key terms, core themes, and character voices.
Audit & Repair Phase: It then audits the entire translation against this master plan. If it finds an inconsistency (e.g., a key phrase translated two different ways), it flags the error and allows you to generate a surgical repair with a single click, rewriting the sentence to enforce the correct, canonical version.

Question 37

Why is the Threadweaver necessary?

Accepted Answer

Because a single missed callback, a broken motif, or a key term translated three different ways can silently sabotage a book's power. Human teams, no matter how skilled, cannot systematically track hundreds of these threads across a 300-page manuscript. Threadweaver prevents this collapse by auditing with the tireless precision of a machine. It guarantees a level of cohesion that traditional methods simply cannot.

Question 38

What languages do you support?

Accepted Answer

You can select from 40+ languages including English, Chinese, Japanese, French, Spanish, German, Hungarian, Russian, and more. But you can toggle the Experimental mode during upload, which allows you to input anything as a target language.

Question 39

Can I use this for fiction? What about poetry?

Accepted Answer

Yes, BookTranslate.ai excels at fiction. Our dedicated Fiction Mode enhances character dialogue, emotional nuance, and narrative voice. It performs well across most genres, from drama to light fantasy. For highly stylized or lore-heavy writing (sci-fi, experimental prose), the system provides an excellent foundation that gets you 80-90% of the way there. Just make sure to toggle the Fiction Mode during upload.

Poetry, however, is not recommended. The system is built for prose and struggles with the non-literal meanings, complex rhythms, and dense metaphors that define poetry.

Question 40

How does the "Experimental mode" for target languages work, and what are its limitations?

Accepted Answer

Experimental Mode is a special option you can toggle during upload that unlocks limitless translation styles and target languages. In normal mode, you choose from our supported list of 40+ languages. With Experimental Mode, you can type in anything as the target “language” – whether it’s a specific dialect, a historical tone, or even a fun stylistic twist. For example, you could ask for Shakespearean English, 1940s Noir-style narration, or even a tongue-in-cheek “Yoda speak” translation. The system will do its best to accommodate creative requests. Important: Because this mode lets you venture outside typical languages, the results can be unpredictable (occasionally hilariously so). We recommend using clear custom instructions alongside experimental requests to guide the AI, and maybe start with a small sample to ensure the style is on point. In short, Experimental Mode is our “choose your own adventure” setting – it gives you ultimate flexibility for tone and language, just use it with care if your project needs precision.

Question 41

Can BookTranslate.ai translate between different dialects of the same language (e.g., UK English to US English, or European Spanish to Latin American Spanish)?

Accepted Answer

Yes, you can guide the translation toward specific dialects by setting custom instructions or using Experimental Mode. For example, if you're translating from French to English and want the result in UK spelling and tone, just specify “British English” as the target. The system will adapt vocabulary, spelling, and phrasing accordingly. Similarly, you can direct it toward Latin American Spanish, Canadian French, or even more stylistic variants like “formal corporate tone” or “casual Gen Z slang” using Experimental Mode.

Question 42

Are there any types of content or genres that BookTranslate.ai is NOT recommended for?

Accepted Answer

While BookTranslate.ai handles nonfiction, essays, and narrative prose very well, it's not recommended for:

Highly poetic or experimental literature with non-literal meanings
Legal or financial contracts where precise legal terms must be preserved
Sacred texts or scripture, due to the need for theological precision
Heavily scanned image-based books or PDFs (we don't currently support OCR)
Children’s books with image-driven context, which the AI can’t interpret

For general nonfiction, fiction, and academic prose, the platform performs excellently - but always consider human review if the stakes are high.

Question 43

How does the system handle translation of idioms, cultural references, or humor?

Accepted Answer

BookTranslate.ai performs surprisingly well at handling idioms, cultural references, and even humor - far beyond what you'd expect from generic AI translation. Our custom multi-pass system doesn't just translate - it refines. In each pass, it reevaluates awkward or overly literal phrasing and replaces it with natural, context-aware equivalents in the target language.

This works especially well for idiomatic expressions, regional sayings, and emotional subtext. Even humor and sarcasm - historically difficult for machines - are often preserved through careful emphasis on tone and narrative voice.

That said, humor that relies on deep wordplay, cultural in-jokes, or puns may still require human tweaks. You can use our glossary to polish those sections. But in most cases, the AI will get you very close to publication-ready, even with complex idiomatic content.

Question 44

Can I translate books that contain dialogue in multiple languages?

Accepted Answer

Yes, mixed-language dialogue is supported - the system will attempt to translate all parts of the text into your chosen target language unless instructed otherwise. If you want certain parts (like character lines in French or Latin) to remain untranslated, you can specify that in the custom glossary or instructions field when uploading. The system is flexible, but by default it will treat all paragraphs as translatable unless told not to.

Question 45

Is there a list of upcoming languages planned for support?

Accepted Answer

BookTranslate.ai already supports 40+ major languages, and more are being tested regularly. While we don’t publish a fixed roadmap, support for additional languages - especially regional dialects and low-resource languages - is coming in future updates. If you need something specific, you can request it via our contact page or try Experimental Mode, which lets you test unsupported targets right away.

Question 46

How do you ensure quality for less commonly translated language pairs?

Accepted Answer

The quality of translation depends on both the language pair and the source text clarity. For lower-resource languages, BookTranslate.ai still uses the same multi-pass refinement system, which helps improve output regardless of the base model’s limitations. We also recommend using custom glossaries and clear author instructions when working with niche language pairs. If a language is labeled “experimental,” that means it may be more prone to rough edges - but the multi-pass approach still does a lot to polish it up.

Question 47

Why do I need to log in to translate?

Accepted Answer

We require login so your translations, glossary, custom instructions and progress are securely saved to your account. This lets you:

Pause and resume translations anytime
Access your projects across devices
Keep your data private and accessible only to you
Share projects via public links if you choose

Translation is a multi-step process, and login ensures you don’t lose your work. We never share or train on your content - everything stays tied to your private account.

Question 48

Can I translate only specific chapters or sections of a book, rather than the entire manuscript?

Accepted Answer

Yes - you’re in full control of what gets translated. If you only want to translate certain chapters or excerpts, you can simply upload those specific sections as a standalone file. BookTranslate.ai treats each upload as its own project, so there's no need to upload the full book if you don’t want to. This is great for authors testing the waters, publishers doing samples, or editors working in batches.

Question 49

Is there a way to pause a translation job and resume it later?

Accepted Answer

Yes, you can pause and continue the process anytime. When a translation begins, you'll see an overlay appear on the website with a pause/resume button and the current progress. You can even pause on a device and continue it on another whenever you'd like.

Question 50

Can I use this AI to translate articles?

Accepted Answer

Absolutely, you can translate any text you want. Just upload the text and let the system handle the rest.

Question 51

Does the platform offer any tools for side-by-side comparison of the original text and the translated versions?

Accepted Answer

Yes. BookTranslate.ai lets you review all five AI-generated passes alongside the original text, paragraph by paragraph. You can easily switch between passes to track how the translation evolves over time, compare different versions, and catch subtle differences or improvements. This level of transparency helps you choose the strongest version and ensures you're never stuck with a black-box result.

Question 52

Can I export each of the 5 passes individually if I prefer an earlier version of a section?

Accepted Answer

Yes - you can export all five passes individually or just pick the one you prefer. After translation, you’ll see download buttons that let you export the raw first pass, the polished fifth pass, or anything in between. If you prefer an earlier version for tone or accuracy reasons, it’s yours to keep. You’re not locked into just the “final” result.

Question 53

How does the platform handle footnotes, endnotes, chapter titles, or other structural elements of a book?

Accepted Answer

BookTranslate.ai keeps basic structural elements like chapter titles, headings, and section breaks intact during translation. It recognizes these elements based on line formatting and typical patterns (e.g., "Chapter 3", "Part I", or markdown-style headers). However, footnotes and endnotes are treated as regular inline text - they are translated just like any other paragraph unless manually removed.

Advanced handling like auto-linking footnote markers, reflowing references, or creating dynamic note formatting is not yet supported. We recommend reviewing and reapplying structural polish (like notes formatting or styling) after translation, especially if your manuscript is heavily annotated.

Question 54

Can I manually edit the translation results on the platform?

Accepted Answer

Currently, the platform does not support full in-browser text editing from scratch. However, you can make targeted changes by accepting or rejecting suggestions from the Finalizer, Naturalizer, and Threadweaver. For a full manual rewrite of a paragraph, you would export the text and use your preferred external editor.

Question 55

Are there any collaboration features for working with an editor or proofreader within BookTranslate.ai?

Accepted Answer

Yes. BookTranslate.ai is built for professional team workflows. You can invite collaborators to any project and assign them 'Viewer' or 'Editor' roles. Editors can review and set the status of all Finalizer and Naturalizer suggestions (e.g., mark them as 'ignored' or 'rejected'), creating a pre-vetted list for the project owner. The owner retains ultimate authority and can then quickly 'auto-apply' the suggestions the editor has approved, dramatically streamlining the review process.

Question 56

What output formats are available for the final translated book (e.g., .epub, .mobi, .pdf)?

Accepted Answer

Currently, all translated passes can be exported as clean .txt files. This ensures maximum compatibility with any word processor or layout software for your final formatting.

Question 57

Does the system preserve formatting from the original document (e.g., bold, italics, lists from a .docx file)?

Accepted Answer

No - BookTranslate.ai currently does not retain advanced formatting from .docx files, such as bold, italics, underlining, bullet points, or styles. The system extracts and processes plain text only. Basic structure like paragraphs, line breaks, and some headings are preserved, but all visual or stylistic formatting is stripped.

If formatting matters for your project, we recommend reapplying it after translation in your preferred word processor.

That said, our system does attempt to preserve markdown-style formatting (e.g., *, #, >). If you convert your .docx file to markdown using an online tool that preserves formatting in markdown syntax, you may be able to retain most of it through the translation process.

Question 58

Is an API available for developers to integrate BookTranslate.ai into other applications or workflows?

Accepted Answer

Not yet, but it’s under consideration. BookTranslate.ai currently runs as a web-based app with no public-facing API. If you're a developer and interested in API access for automation, bulk translation, or integration with publishing tools, we’d love to hear from you. Feel free to email hello@booktranslate.ai to register interest - we’re actively collecting feedback on potential use cases.

Question 59

Will the AI suggest terms for my glossary based on the content of my book?

Accepted Answer

Yes. During the initial 'AI Literary Analysis' phase, the system reads your entire book and automatically identifies recurring key terms, names, and concepts. It then presents these to you as a 'Suggested Glossary' with contextual translations. You can toggle these AI suggestions on or off, and add your own terms to create the definitive glossary that will be strictly enforced throughout the translation.

Question 60

Are there any limits on the number of terms or phrases I can add to a custom glossary?

Accepted Answer

There’s no hard cap, but for best results, we recommend keeping your glossary under a hundred entries. Each glossary is injected into the AI’s context window during translation, so extremely large glossaries may reduce model performance or cause context clipping. For most books, even 30–100 terms is enough to maintain consistency without overloading the prompt.

Question 61

Can I import or export glossaries, for example, from a CSV file?

Accepted Answer

Not yet - glossary entries are currently added manually through the upload form. CSV import/export is on the roadmap, and we know it would make term management much easier for large projects.

Question 62

How does the system handle conflicts if a glossary term could be translated in multiple ways depending on context?

Accepted Answer

The glossary acts as a hard constraint: if a term is defined there, the AI is instructed to use the specified translation every time it sees that term. This ensures consistency, but it also means nuanced or context-sensitive translations may be overridden. If a word could have multiple meanings, we recommend not adding it to the glossary - or using clarifying instructions (e.g. “Translate ‘right’ as ‘correct’, not a direction”).

Question 63

Can I share my glossaries across multiple book projects?

Accepted Answer

Not automatically. Each glossary is currently tied to a specific upload, so if you want to reuse a set of terms, you’ll need to manually copy them over when uploading your next book. Cross-project glossary management is a planned feature, and we’re actively designing ways to let users save, reuse, and manage multiple glossaries more easily.

Question 64

Can I review each pass myself?

Accepted Answer

Yes, you have complete transparency. After translation, you can use our pass-by-pass viewer to see the original text alongside all five AI passes. For a deeper review, the Context Viewer allows you to see any Finalizer or Naturalizer suggestion within the full context of its surrounding paragraph, ensuring you never have to make a decision in a vacuum.
