Immersive Translate

A browser extension for bilingual side-by-side webpage translation, with support for PDF, video subtitle, and EPUB ebook translation.

Immersive Translate is a browser extension that provides bilingual side-by-side webpage translation — the original text and its translation are displayed side by side rather than replacing the original, which is its core distinction from tools like Google Translate. This design lets users understand the content while learning the language by comparing against the original, making it especially well-suited for reading foreign-language news, technical documentation, and academic papers. As of 2026, Immersive Translate supports more than 10 translation engines (DeepL, Google, Tencent, OpenAI GPT-4o, Claude, and more), and users can switch freely based on content type and budget. Beyond webpage translation, it also supports PDF document translation (with formatting preserved), EPUB ebook translation (bilingual side-by-side), and video subtitle translation (real-time bilingual subtitles on YouTube and Netflix).

The free version offers basic webpage translation and limited PDF translation; Pro, at $9.99/month, unlocks all translation engines, unlimited PDF/EPUB translation, video subtitles, and priority support. Immersive Translate’s pricing sits in the mid-range among translation tools, but its unique “bilingual side-by-side” experience makes it irreplaceable in certain scenarios.

In terms of market positioning, Immersive Translate is a differentiated player among browser translation extensions — unlike Google Translate’s “replace the original” approach, it emphasizes “side-by-side reading”; and unlike DeepL’s focus on “document translation,” it concentrates on real-time webpage translation. Its user base consists mainly of researchers, developers, students, and language learners who frequently read foreign-language content. After integrating GPT-4o and Claude in 2026, translation quality improved significantly, approaching DeepL’s level at a lower cost. It is ideal for users who need to read large volumes of English technical documentation, news, and academic papers.

Note: A browser extension installation is required (Chrome/Edge/Firefox/Safari); the free version is subject to daily translation quota limits; video subtitle translation currently supports only YouTube and Netflix; some complex pages (e.g., heavily JS-rendered SPAs) may fail to correctly identify content areas.
