What is Lingosive?

One account, three ways to use it

Chrome extension. In a browser on your computer, Lingosive shows the subtitles on YouTube, Netflix, Prime Video, Disney+ and HBO Max in two lines: the original line in the language you're learning and a translation into your own language underneath. Hover over a word for a quick translation; click it to see other meanings, the pronunciation and the lines where it appears, and add it to your word list. Install it from the download page; there's a setup guide for each platform under dual subtitles.

Mobile app. For iPhone and iPad (iOS 16.4 or later) and Android (7.0 or later). Watch a curated library of YouTube videos with a translation line, read books, and review your saved words with spaced-repetition cards. The app does not play Netflix or the other streaming services. More on the mobile app page.

Web learning center. At lingosive.com/learn, with nothing to install: videos with dual subtitles, your saved words, review cards and Word in Film. In Word in Film you type a word or a short phrase and watch short movie and TV scenes where it's said.

All three use the same account (sign in with Google, Apple or email), so a word you save in one place shows up in the others.

Where it works and where it doesn't

Works:

• YouTube videos on youtube.com, Netflix, Prime Video (on primevideo.com and on the video pages of amazon.com, amazon.co.uk, amazon.de and amazon.co.jp), Disney+ and HBO Max, in a browser on a computer.
• Chrome, Edge, Brave and other Chromium-based browsers (Chrome 111 or later). The extension is installed from the Chrome Web Store, in Edge too.

Doesn't work:

• Firefox and Safari: there is no version for them, and no separate listing in the Edge Add-ons store either.
• The Netflix, YouTube and other apps on phones, tablets and smart TVs: those apps can't run browser extensions.
• YouTube Shorts, YouTube Music and YouTube players embedded on other websites.
• Other services such as Crunchyroll, Viki, Apple TV+, Paramount+ and Hulu, and video files on your computer.

Right-click translation and the selected-text translator work on any website, but they are not dual subtitles.

Languages

• The interface is available in 13 languages: English, Spanish, German, French, Italian, Turkish, Portuguese, Hindi, Russian, Japanese, Korean, Simplified Chinese and Traditional Chinese.
• Your own language, used for the translation line and for word meanings, comes from a much longer list: 68 languages in the extension.
• Word-level tools (clickable words, the word card) work best in 37 subtitle languages.
• Word in Film covers English, Spanish, French, German and Japanese on the web and in the extension; the mobile app adds Italian, Portuguese and Russian.
• The app's video library and card practice are available in 8 languages: English, Spanish, French, German, Italian, Portuguese, Russian and Japanese.

Free plan and Premium

Installing the extension and using dual subtitles is free, and dual subtitles and word translations work without an account. A free account lets you save up to 100 words, and each day you get 10 Lingosive AI explanations and Word in Film searches for 3 different words or phrases. In the mobile app you also get 5 minutes of video a day and the first 20 pages of every book. Premium removes these limits. Plans and current prices are on the pricing page; prices can vary by country. Common questions are answered in the FAQ.
