Product · Document Translator

Translate real documents. Keep the layout.

Most translators flatten your file into a paragraph of text and hand it back with the styling gone. Ours doesn't. It parses your DOCX or PDF into a layout-aware Document IR, translates each paragraph with our own AI engine, then redistributes the translated text back into the original styled runs.

Why it's different

Layout-first architecture

Files pass through a Document IR — paragraphs, styled runs, alignment, headings — so translation never destroys the source structure.

40+ languages, one engine

European, Middle Eastern, South Asian and East Asian languages, with auto-detect on the source side.

Batched + deduped

Up to 40 paragraphs per gateway call with a 4-way concurrent worker pool and per-job dedup. Real docs finish in seconds, not minutes.

No third-party keys

We run our own translation service on top of our AI gateway. No DeepL, Google or Yandex account to wire up.

Supported formats

DOCX

Full round-trip. Headings, bullets, bold/italic runs preserved.

PDF

Text-based PDFs. Rebuilt as translated DOCX for editability.

TXT

Passthrough. Paragraph structure kept intact.

Markdown

Headings, lists and paragraphs preserved.

Under the hood

  1. 1

    Parse

    The file is unpacked into a Document IR — an ordered list of paragraphs, each with its own styled runs.

  2. 2

    Translate

    Paragraphs are batched, deduped and translated by our own AI engine with strict JSON-schema output for reliability.

  3. 3

    Render

    Translated text is redistributed back into the original runs and re-packaged as DOCX, PDF or plain text.
