Why Bilingual Reading Beats Full Translation
Full-page translation loses context — you cannot verify accuracy or learn vocabulary because the original text disappears. Immersive Translation solves this by showing both the original and translated text simultaneously, paragraph by paragraph. This "bilingual reading" approach is used by over 1 million users for language learning, academic research, and cross-language information access.
What is Immersive Translation?
Immersive Translation (沉浸式翻译) is a browser extension that translates web pages while preserving the original text in a bilingual format. Each paragraph shows the original language above and the translation below. It supports 10+ translation engines (DeepL, Google, OpenAI, etc.) and works on any website, PDF, EPUB, and even subtitle files. It has exploded in popularity among Chinese users accessing English content and vice versa.
