Frequently Asked Questions
Everything you need to know about Torii's document translator.
What file types can I translate?
Torii supports PDF, DOCX (Microsoft Word), EPUB (eBooks), PPTX (PowerPoint presentations), XLSX (Excel spreadsheets), SRT and ASS subtitle files, plain TXT, and Markdown (.md) files. You can translate multiple files at once in a single session.
How accurate is the AI translation?
Torii uses state-of-the-art large language models such as Gemini, GPT, Claude, and DeepSeek to produce natural, context-aware translations. Unlike older machine translation tools, these models understand nuance, idioms, and domain-specific language — making them significantly more accurate for complex or literary text.
Does the translation preserve the document layout?
Yes. Torii is designed to preserve the original structure of your document as much as possible. For DOCX files, paragraph styles, headings, and tables are maintained. For EPUB files, the chapter structure and formatting is preserved. PDF translations extract text content and deliver it in a clean, readable format.
How much does it cost to translate a document?
Translation cost depends on the document's length and the AI model selected. Torii uses a credit system — you can estimate the cost before translating.
Can I translate Japanese light novels or manga scripts?
Absolutely. Torii was originally built for the scanlation and fan-translation community. It excels at translating Japanese, Korean, and Chinese fiction, including light novels (EPUB/TXT), manga scripts, and visual novel scripts. The AI models used are trained on a wide variety of source material and handle Japanese honorifics, character speech styles, and cultural nuance well. Note that this tool works on text-based files only — if you need to translate manga pages or images directly, check out the Torii Image Translator instead.
Is my document kept private and secure?
Documents are processed in your browser where possible and sent to AI model APIs only for translation. Torii does not permanently store the content of your documents. Please review our privacy policy for full details on data handling.
