About Immersive Translate
FreeBeginner-friendlyNo APIWeb · Mobile · Plugin
Immersive Translate is a free, open-source browser extension that delivers bilingual translations on any webpage, PDF, EPUB e-book, or video subtitle (YouTube, Netflix, etc.). It supports over 50 languages and lets you choose from multiple translation services including DeepL, Google Translate, OpenAI, Microsoft Translator, and more. The extension preserves the original text alongside the translation, making it ideal for language learners, researchers, and professionals who need to verify accuracy. Privacy-focused: no user data collection, translations processed client-side or via chosen API. Available on Chrome, Edge, Firefox, Safari, Android, and iOS. Core features are free with no usage limits; premium translation services may require their own API keys or subscriptions.
Behind the Verdict
Immersive Translate excels at its core mission: making foreign-language content accessible without losing context. The bilingual display is ideal for verifying translations and learning. It supports a wide range of formats (web, PDF, EPUB, video subtitles) and translation services, which is rare for a free tool. Privacy is a strong point — no data collection and client-side processing. However, it's not a full translation management system. There's no offline mode, team features, or real-time speech translation. Mobile apps have fewer features than the desktop extension. For individual learners and professionals who need quick, accurate translations, it's a solid free option.
