Chapter One — bilingual review
Translationالمصدر
Juha sold his house, but kept one nail in the wall.
باع جُحا داره، لكنّه أبقى مسمارًا واحدًا في الجدار.
Every day he came to admire it, hanging his cloak, then his hat.
وفي كل يومٍ كان يأتي ليتأمّله، يعلّق عليه عباءته، ثم قبّعته.
Then he hung a dead donkey on the nail, and the buyer fled his own house.
ثم علّق على المسمار حمارًا ميتًا، فهرب المشتري من داره.

From manuscript to faithful translation

A pipeline built for books, not snippets — with two gates standing between draft and done.

01

Upload

Drop in a manuscript — Word (.docx), Markdown or plain text — or just paste it. We segment it into chapters and paragraphs.

02

Translate

The engine renders each segment in small, faithful chunks, conditioned on the Anchor and your glossary.

03

Two gates

A structural gate checks coverage, images, and terms; a stronger model runs a separate semantic gate. Verification comes with a paid plan.

04

Review & ship

Approve sentence by sentence in the bilingual workspace, then export a clean manuscript.

Where fluent mistranslations go to die

The hard part of book translation isn't grammar — it's keeping meaning, voice, and consistency across hundreds of pages.

Bilingual review

Source and translation side by side, sentence-aligned. Cross-highlight any passage to see its mate.

Glossary consistency

Names, terms, and recurring phrases render the same way everywhere — enforced on every run.

Human-in-the-loop

Approve, comment, and suggest edits sentence by sentence. Nothing ships without a human's nod.

The Anchor

A conditioned ground-truth context travels into every prompt — catching drift a fluent guess would hide.
