Description
AI bilingual web page translator with side-by-side reading, selection translation & built-in dictionary. Supports 6+ languages. This extension requires you to provide your own AI API key. It is NOT a free translation service — it will not translate anything for you out of the box. If you don't know what an API key is, please research before installing to avoid disappointment. iTranslate lets you read any webpage in your language, as naturally as if it were written that way. Why You Need iTranslate Over 70% of internet content is in a language you might not speak natively. Technical documentation, research papers, industry news, product reviews — the best information is often locked behind a language barrier. Traditional solutions force you to switch between translation tools and the original page, breaking your reading flow and losing context. iTranslate takes a different approach: it embeds AI translations directly below the original text, in a slightly muted style. No tab-switching. No full-page replacement. Original and translation coexist in the same view — read what you understand, glance down when you need help. One seamless experience. What Makes It Different Most page translators do "replacement" — they swap the entire page with machine-translated text. Two problems: you lose the original for cross-referencing, and page layouts often break. iTranslate does "overlay" — the original stays untouched, and translations are inserted beneath each paragraph as a supplementary layer. The page structure, images, code blocks, and styling remain intact. Think of translations as "subtitles" for the web. Key Advantages AI-powered, not machine translation. iTranslate calls large language models — GPT, DeepSeek, Claude — not statistical MT engines. It understands context, recognizes technical terms, and handles complex sentences. Translation quality far exceeds built-in browser translation. You use your own API key. iTranslate doesn't sell translation as a service. It's a bridge between you and the AI model you choose. Your data goes directly from your browser to your designated API provider. No intermediary servers ever touch your data. All data stays local. API keys, translation cache, language preferences — everything lives in your browser. No account registration, no data upload, no ads, no tracking. Your browsing privacy and translation content are entirely under your control. Translation cache saves you money. Translated sentences are cached locally. Encounter the same content again and results appear instantly, with zero API cost. Cache hit rates are high when browsing multiple pages on the same site.
