Immersive Translate is a browser extension that displays bilingual translations of web pages, PDFs, e-books, and video subtitles directly alongside the original text. The tool launched in 2022 and has grown to more than 20 million users, earning recognition as Chrome's Best Extension for 2024.
Rather than replacing the source text, Immersive Translate overlays a translated line beneath or beside the original, so readers keep the source language visible for context, useful for language learners and researchers cross-checking technical terms. The extension routes translation through more than 10 engines including DeepL, Google Translate, and OpenAI models, letting users pick an engine per site or fall back automatically if one is rate-limited.
Immersive Translate suits language learners, researchers, and international readers browsing foreign-language sites and papers on a recurring basis, more than someone needing a one-off translation. The extension is free to use with its default engines; a premium subscription at $4.99 a month or $39.99 a year unlocks unlimited use of premium translation engines like DeepL and OpenAI without the free tier's usage caps.
