Bilingual PDF Translation
Sometimes the translation alone is not enough: proofreading needs the original, citation needs the original sentence, and language learning is largely about seeing how the other language put it. A bilingual, parallel-text translation keeps both in one file, so you are not switching between two.
Upload a document for a bilingual translation
Bilingual output produces an extra file alongside the translation — a PDF and a Word document in which each paragraph appears in both languages, one directly after the other.
Geyi bilingual output adds a PDF and a Word file alongside the translation, with each paragraph in both languages one directly after the other, for proofreading, citation, language learning and client delivery.
Key capabilities
- Extra PDF and Word with original and translation interleaved by paragraph
- Comes in addition to the translation, not instead of it
- Independent of layout mode and precision
- Stacks with source page numbers for checking back
- Gated by plan tier, as the pricing page comparison shows
When it earns its place
- Proofreading and review: check paragraph by paragraph without a second window.
- Academic citation: take the original sentence straight from the interleaved file.
- Language learning: seeing both versions of the same paragraph teaches more than the translation alone.
- Client delivery: when the other side wants to check the source, one file covers it.
Turning it on
Tick bilingual output when you submit on the file translation page. It is independent of layout mode and precision — three separate choices. The bilingual file comes in addition to the translation, not instead of it.
The capability is gated by plan tier; the pricing page's comparison table shows which tiers include it.
How it relates to source page numbers
They stack. Every translated paragraph already carries the page it came from, which is for jumping back to the book; bilingual output puts the original right next to the translation, which is for line-by-line checking. Close reading wants both.
Geyi compared with generic machine translation and a manual workflow
The generic machine translation and manual workflow columns describe common cases; actual results vary by tool and method. The Geyi column lists only capabilities that are live in the product today.
See it in action
The first three pages of NASA’s magnetic-gear paper are processed through layout-preserving and reflowed bilingual pipelines, showing two columns, a specification table, captions and alternating English and Simplified Chinese paragraphs.
Bilingual reflow, opening page: English paragraphs followed by Simplified Chinese translations, from the three-page source excerpt.
Bilingual reflow, specifications: original Table 1 and its Chinese table are re-typeset, retaining the source values and units.
Generated through Geyi’s pipeline, then checked against the source and edited for display.

Frequently asked questions
What format is the bilingual file?
A PDF and a Word document, with original and translation interleaved paragraph by paragraph.
Does it cost extra credits?
The bilingual file is produced alongside the translation; the job is still billed on page count and the precision you chose, and the estimate shown before submission covers the whole run.
Is it available on every plan?
It is gated by plan tier — see the entitlement comparison on the pricing page.
Can scans produce a bilingual version?
Yes. Scans go through AI reflow and can produce the bilingual file just the same.
Can I add it after the fact?
It is produced while the job runs, so if it was not ticked, resubmit the job with the option on.
Can the bilingual file be edited?
The Word version can be edited directly; the PDF suits reading and archiving.
