ToolifyNav verdict
Immersive Translate solves a specific reading problem well: seeing a foreign text and its translation together without losing your place. That parallel view, applied consistently across web pages, academic PDFs, ebooks and video subtitles, is why it belongs in the education category rather than being just another translator. The engine choice is a bonus for people who prefer DeepL for European languages or a large language model for technical prose. Its token-based plans take some decoding, and it does not replace professional localization. For self-directed learners and researchers, it is among the most practical translation tools around.
About
About Immersive Translate
Immersive Translate is a browser extension and companion app that keeps the original text visible while inserting a translation beneath each paragraph, which is why it is popular with language learners and researchers reading foreign sources. It started on Chrome and now runs on Edge, Firefox and Safari, as a userscript, and on iOS and Android, with the company claiming more than 30 million users.
Coverage is wide. Web pages translate in place, including sites such as Steam and AO3. PDF translation comes in two flavors, with PDF Pro and the BabelDOC engine preserving the layout of papers and reports. ePUB books, Zotero libraries and Google Docs are supported. For video, it adds bilingual subtitles on YouTube, Netflix and other players, generates AI subtitles for videos without them, translates YouTube live streams and online meetings, and exports subtitle files. Image, comic and screen-area translation handle text inside pictures, and input-box translation helps when replying in another language.
Users choose among more than 20 engines, including DeepL, DeepSeek, Gemini, Claude and OpenAI models, and can apply terminology libraries for consistent wording. The company says translated content is not retained or used for training and cites ISO 27001 and ISO 27701 certification.
