Blab Translation

Free bilingual web page translation. PDFs keep their layout, dual YouTube subtitles, EPUB/Word, comics. Bring your own AI model.

Blab Translation — read anything in two languages. Original and translation side by side, on web pages, PDFs, ebooks, videos and comics. Bring the AI you trust local models — or Chrome's free on-device translator. ★ BILINGUAL WEB PAGES • Translation under every paragraph. Formatting, links and images untouched. • Translation only? One key: Alt+T. • Main content first — menus and sidebars stay out of the way. Alt+W for the whole page. • Reaches inside iframes and Shadow DOM. • Math, LaTeX and code stay intact. Papers stay readable. • 6 translation styles. 76 languages. Right-to-left done right. ★ AUTO-TRANSLATE THAT KNOWS WHEN TO STOP • Sentences already in your language are skipped — even when packed with foreign terms. • Private messages are never auto-translated. • Site rules: point at any area — "Don't translate", "Keep original" or "Only translate here". Pin an engine, add CSS. Rules sync with your account. ★ PDFS THAT KEEP THEIR LAYOUT • Bilingual or translation-only PDFs, with figures, formulas and layout exactly where they were. • Free pages every month with sign-in. ★ EBOOKS & DOCUMENTS • Word, EPUB, TXT and Markdown → bilingual or translated files. • MOBI and AZW3 read bilingually in the web reader. ★ DUAL SUBTITLES • YouTube subtitles translated live: original and translation, two lines. • Works with any HTML5 player that has a standard subtitle track. • One-click toggle right in the player's control bar. ★ SELECT, HOVER, LOOK UP • Select text to translate — retranslate, switch engine, copy, read aloud. • Built-in dictionary for words and phrases: pronunciation, senses, examples, word forms. • Hold a modifier key and hover to translate a single paragraph. • Typing in a different language from the page? Translate it with one click. ★ COMICS & IMAGES • Comic pages redrawn in your language — and colorized if you like. • Text in images recognized by on-device OCR, then translated. ★ PRIVATE BY DEFAULT • Web pages translate on your device by default. Your text never leaves your computer. • With an AI engine, text goes straight to your endpoint with your own key — never through us. • PDF, document and comic files are processed on our servers and deleted after 7 days. • No analytics. No ad tracking. SHORTCUTS Alt+A translate / restore · Alt+T bilingual / translation only · Alt+W whole page · Alt+M PDF or comic Privacy policy: https://blab-translation.com/app/legal/privacy
