- Fix names, terms, and phrasing by hand
- Lose formatting, structure, and layout

Powerful features to transform your reading experience
Built for whole books, not just sentences. From context-aware translation to layout that stays intact, every detail is handled so you can just read.
Context-aware translation
Our AI reads each passage in full, capturing tone, nuance, and cultural meaning, so every chapter flows as naturally as the original. Never word-by-word.
“It's raining cats and dogs our there.”
外面正在下着猫和狗。
外面下着倾盆大雨。
Auto glossary
BookTranslator tracks every name, place, and key term and applies them consistently across the whole book with a built-in glossary, so a character is never renamed halfway through and technical terms stay accurate from first page to last.
The rain hammered down on London, echoing the tension in Sherlock Holmes' study at 221B Baker Street. Watson glanced nervously at the telegram from Mycroft, knowing that Moriarty's shadow loomed ever closer.
雨水猛烈地敲打着伦敦，映照出贝克街221B号福尔摩斯书房里的紧张气氛。华生紧张地瞥了一眼迈克罗夫特的电报，知道莫里亚蒂的阴影正日益逼近。
Layout preservation
Tables, images, footnotes, and formatting stay exactly where they belong. Your translated file looks just like the original, with zero cleanup.
OCR for scanned PDFs
Built-in OCR reads text straight off scanned books and image-only PDFs, then translates it cleanly, so even old scans and photographed pages become readable in any language.
Bilingual reading
Read the original and the translation side by side, to check accuracy, study a new language, or savor the author's exact words. Download bilingual version anytime.
Under the pale crescent moon, Elara moved silently through the ancient woods. Her breath barely stirred the cool night air, blending with the soft rustle of leaves. Each step took her further into the depths where mysteries lay dormant, waiting for the morning light to reveal their stories.
在淡淡的新月光下，艾拉悄无声息地穿行于古老的树林中。她的呼吸几乎未搅动凉爽的夜风，融入树叶的轻轻沙沙声中。每一步都将她带入更深的林间，那些沉睡的秘密等待着晨光揭示它们的故事。
The forest seemed to hold its breath, and so did she. Poised between the unknown and her destiny, Elara felt the weight of discovery pressing close.
森林仿佛屏住了呼吸，她也是。艾拉站在未知与命运的交汇处，感受到发现的重压近在咫尺。
