Overview
Immersive Translation is a revolutionary browser translation plugin that adopts a "bilingual comparison" translation method—retaining the original text while displaying the translation below each paragraph. This approach allows users to see the original text for accuracy while quickly understanding the content through the translation, offering the best experience for reading foreign language web pages.
Immersive Translation supports mainstream browsers such as Chrome, Firefox, and Edge, and can connect to multiple translation engines including DeepL, Google, and ChatGPT. It also supports translation of offline documents such as PDFs, ebooks (EPUB), and subtitle files.
**📌 2026 Update**: Immersive Translation has evolved from a "web translation plugin" to a **full-scenario AI translation tool**—the web version supports **online video subtitle translation** (YouTube, Netflix, etc.) + **real-time meeting translation** (Zoom, Meet) + **PDF translation** + **manga translation**. The built-in engine has expanded to **20+ top AI translation engines** (including new domestic models like DeepSeek, Gemini, and Kimi K3), with full support across all platforms (Chrome / Edge / Firefox / Safari / iOS / Android / macOS / Windows).
