Quick answer
Belin Doc is an AI document translator built around one requirement: the file you download should be usable straight away, with its layout, tables, and numbering intact — not a text dump you have to rebuild.
What formats it handles
- PDF, including scanned PDFs via OCR
- Word — note that Word files must be
.docx; a legacy.docneeds to be saved as.docxfirst - Excel and PowerPoint
- EPUB, TXT, and Markdown
- Images and photographed pages
What it does beyond translating the words
- Rebuilds the document structure rather than replacing text in place, so tables and multi-column pages survive
- Freezes Excel formulas so calculation logic is not translated — see preserving formulas
- Applies a glossary so terminology stays identical across a long file
- Offers side-by-side comparison of source and translation before you download
Related tools that come with it
- Split, merge, and compress PDFs
- Flatten scanned PDFs into a single layer
- Convert between PDF and Word, PDF and EPUB, and PDF and Markdown
- Video translation with subtitles and dubbing
Who it fits
- Anyone whose documents have structure worth keeping — specifications, manuals, financial models, papers
- Teams that need the same terminology across many files, via shared glossaries and organization accounts
- Organisations with data-residency requirements, via private deployment
Bottom line
The point of Belin Doc is what you get back: a document you can use, rather than a translation you have to reassemble.
