About this extension
Watch Netflix with two subtitle languages on screen at the same time — the language you are learning and your own — and study phrase by phrase.
FEATURES
• Dual subtitles: any two of the title's subtitle languages, stacked, or split between the top and bottom of the screen.
• All the subtitle tracks the title offers, not just the ones in Netflix's menu.
• Machine translation of the learning subtitle as a third line.
• Aligned lines: the native subtitle shows the sentence that matches the phrase you are hearing.
• Phrase navigation: jump to the start of the phrase, to the previous or next one, or pause automatically at the end of each phrase.
• Playback speed with a favourite speed, and audio/dub track selection.
• Size, colour, outline and position for each line; right-to-left languages rendered correctly.
• Interface in 47 languages.
KEYBOARD SHORTCUTS
S settings panel · B/Q rewind · G/E forward · N/A start of phrase · H/D next phrase · X pause at the end of each phrase · V/Z/T hide learning/native/translation · C hide controls · , and . slower/faster · K favourite speed
PRIVACY
No account, no analytics, no ads. Your settings stay in your browser. Machine translation is off until you turn it on; in Chrome it then runs on your device, and in Firefox, which has no on-device translation, it uses a remote engine that sends the subtitle text to Google Translate.
Free, with no ads and no tracking. Donations are welcome but optional, and unlock nothing.
