Three steps to delivery
-
01
Submit the document
Upload the source. Language and fine layout are detected automatically — complex long documents settle in safely.
-
02
Deep translation
Convert by paragraph and specialist terms with precision. Charts and layout stay intact; the texture of the prose is not diluted.
-
03
Deliver the manuscript
Export an editable translation and review side by side — ready for business signing and academic archives.
Why choose CrossDoc AI?
-
01
Layout restored as it was
PDF, Office, ePub, even code and design files. Deep parsing keeps paragraphs, tables and figures in place — the translation sits where the source sat.
-
02
Models as the pen
Leading large language models hold the pen. They read context and specialised reasoning, so the line is fluent and native — not a word-for-word swap.
-
03
Read both, then revise
A parallel manuscript is made for line-by-line checking. Fine-tune the target, then regenerate the document from those revisions.
-
04
Terms as you name them
Keep a private glossary so brand names and field-specific nouns stay consistent. Multilingual mapping suits medicine, law, finance and neighbouring crafts.
-
05
Memory that grows with the page
When a new document opens, the system searches your private memory for kindred sentences, so tone and cadence stay as close as they can.
-
06
Cloud async processing
No need to stay on the page waiting anxiously. Hundred-page documents are handled steadily in the background — wait for the finished draft, then download anytime or open it from history.
Frequently asked questions
Which document formats can I translate?
We support the vast majority of mainstream professional and office formats, mapping each structure faithfully through the whole translation process:
- Office and text: Word (.docx), Excel (.xlsx), PowerPoint (.pptx), TXT / Markdown (.md)
- Deep layout and reading: PDF (.pdf), ePub ebooks (.epub)
- Audio-video and localisation: SRT subtitle files (.srt)
Our parsing engine keeps iterating, and we will continue to add dedicated formats for more specialised fields.
How long does it take to translate a document?
Processing time depends on page count, word count and layout complexity. With deep structure parsing and large-model semantic refinement, a typical document (such as a contract or report of several thousand words) usually finishes in tens of seconds to a few minutes. For hundred-page academic papers or complex financial reports, the system aligns layout page by page and polishes in depth, so a little more patience is needed.
Note: You do not have to stay on the page. Processing runs in the background; when it finishes, you can download the result or find it in your history.
How good is the translation quality, really?
Powered by the industry’s leading large language models, we go beyond literal conversion: we grasp context, specialised terms (legal clauses, academic nomenclature, financial metrics) and industry conventions. You get industrial-grade, high-precision semantic refinement at the current peak of AI translation — sharply cutting later human proofreading on professional documents.
Is the service free?
We use a transparent try-before-you-buy model. New users receive a free trial allowance on signup — enough to fully translate a short contract, paper abstract, or report excerpt. When the allowance is used up, we offer flexible, good-value on-demand credits and plans. You pay by actual word count, with no hidden subscription traps.
Do translated PDFs keep their original layout?
Yes. We use an advanced PDF deep-structure engine that accurately identifies and extracts text, columns, figures and layout hierarchy from the original. After large-language-model semantic refinement, the system reconstructs the source layout with high precision, so the translation matches the original visually and you do not have to reformat by hand.
Are my documents stored after translation?
To let you review and download history at any time, your documents are held privately on our servers with strong encryption:
- We keep them for 7 days so you can download them again whenever you need.
- Meanwhile you can click Delete in the dashboard at any time; related files and translations are erased at once, with nothing left behind.
Are my documents and data secure? Will they be leaked or used to train large models?
We understand the confidentiality of contracts, financial reports, academic papers and official documents, and apply strict industrial-grade data security and privacy standards:
- Encryption throughout: All files use strong encryption during upload, transit and cloud processing.
- Never used for training: Your document contents, translations and business data are never used to train any public large language model, and are never disclosed to third parties.
- Timed destruction: After processing, files are kept only for a short, secure period, and you can erase them completely at any time.
