What Immersive Translate is
Immersive Translate provides free bilingual web translation along with translation for documents, literary works, PDFs, EPUB ebooks, subtitle files, and plain text. Language coverage is wide, including Chinese, English, Japanese, Korean, French, German, Russian, Spanish, Portuguese, Vietnamese, Indonesian, Italian, Dutch, and Thai. You can choose between several translation engines, among them DeepL, Google, OpenAI, Youdao, Caiyu Xiaoyuan, Baidu, Volcano, and Xiaoniu, which matters because different engines handle different text types differently. The bilingual approach is the whole design: the original stays on screen, so you can check the translation and pick up language at the same time.

What to watch out for
Free translation is the stated offer, but some engines behind it require their own accounts, keys, or quotas, so the free part is the wrapper rather than every engine. Accuracy varies by engine and by text difficulty, and literary or technical passages still reward a check against the original. PDF and ebook translation can disturb layout, and complex formatting may not survive. The extension also reads the pages you visit in order to translate them, which is worth understanding if you work with sensitive material. Features and interface details may change between versions, so review the latest notes on the page before you start.
