DualView Translator

Browser translation that shows the original and translation side by side. Selection and full-page modes.

Tired of translation tools that swallow the original text? DualView Translator keeps it right there — the translation slides in **right under** the original, so you never lose the context. Great for language learners, anyone reading foreign articles, or when you just want to double-check what a translator gave you. ■ What you get - **Dual-view display** — the translation appears right under the original, no jumping back and forth - **8 translation modes** — pick what fits: a single line, the whole page, just one element, with or without AI summary - **Auto-translation rules** — set up your favorite sites once, and they get translated automatically when you open them - **Translation reset** — undo per element with the × button, or wipe everything in one tap - **Two engines** — Google Translate (free, no setup) or DeepL (sharper translations) - **AI summaries** — Claude or Gemini sums up the translated content in 3–5 lines - **Tabbed popup** — translation actions and settings, neatly separated - **Keyboard shortcuts** — Ctrl+Shift+T, you know the drill - **11 UI languages** — Japanese, English, Chinese (Simplified/Traditional), Korean, French, German, Spanish, Portuguese, Russian, Arabic - **Dark / Light theme** — follows your OS, no fuss ■ The 8 translation modes 1. **Selection translation** — highlight text, the panel pops up 2. **Full-page translation** — translate the whole page in dual view 3. **Full-page + AI summary** — translation plus a quick overview 4. **Element selection translation** — click the element you care about 5. **Element selection + AI summary** — same, but with a summary 6. **Right-click translation** — select text, right-click, done 7. **Element translation (right-click)** — right-click on a block to translate it 8. **Element translation + AI summary** — same, with a summary ■ The translation bar Open a foreign-language page and a small bar pops up at the top. One click to "Translate", one click to "Translate & Summarize". That's it. ■ Auto-translation rules Got a site you read in another language every day? Register it once with a URL pattern, narrow down to the part you care about with a CSS selector (or just click the element to generate one), and you're set. Works with SPAs, dynamic content, even webmail. ■ Dynamic content Lazy-loaded sections, infinite scroll — they get picked up and translated as they appear. No need to keep clicking "translate" again. ■ Translation engines - **Google Translate**: free, no API key, ready to roll (default) - **DeepL**: better quality. Free tier covers 500,000 characters/month ■ AI summaries Hook up Claude (Anthropic) or Gemini (Google) and get a quick 3–5 line summary of the page you just translated. API key needed for these. ■ Privacy, plain and simple - Your text only goes to the translation engine you picked - API keys live in your browser's local storage, nowhere else - No history collection, no tracking, no data goes to us
