YouTube Subtitles + — Improved and Dual-Language Subtitles for YouTube

Watch any YouTube video with improved default subtitles or use two languages at the same time. YouTube Subtitles + automatically translates captions in real-time and displays them alongside the original text — perfect for language learners, bilingual viewers, or anyone watching foreign content.

🌍 HOW IT WORKS
Turn on captions on any YouTube video. YouTube Subtitles + instantly detects them, translates them into your chosen language, and displays both the original and translated text as a clean overlay on the video. No copy-pasting. No switching tabs. It just works.

🎯 KEY FEATURES
• Massive improvment on default Youtube Captions — Changes the default choppy looking captions into an actual readable format. 
• Dual subtitles — See both the original and translated captions at the same time
• 15 languages — Spanish, French, German, Italian, Portuguese, Russian, Japanese, Chinese, Korean, Arabic, Hindi, Dutch, Turkish, Polish, and English
• Real-time translation — Captions are translated as they appear with no noticeable delay
• Three translation engines — Google Translate (recommended, free, no setup), DeepL (highest quality, free API key), and MyMemory (basic fallback)
• Fully customizable — Change text color, size, font, background color, and opacity
• Flexible positioning — Place subtitles at the top, center, or bottom of the video
• Native caption hiding — Optionally hide YouTube's default captions to avoid overlap
• Works instantly — Install, pick your language, and start watching. No account needed.

📚 GREAT FOR LANGUAGE LEARNERS
Reading subtitles in two languages simultaneously is one of the most effective ways to learn vocabulary and improve comprehension. See how words and phrases translate in real context while watching content you actually enjoy.

🔒 PRIVACY
YouTube Subtitles + does not collect, store, or transmit any personal data. All settings are stored locally on your device. Translation requests are sent directly to the translation service you choose — nothing passes through our servers.

⚡ LIGHTWEIGHT
No bloat, no ads, no premium paywalls. Every feature is free. The extension only activates on YouTube video pages and uses minimal resources.

💡 TIPS

• Google Translate is selected by default and works with no setup
• For the best translation quality, try DeepL with a free API key from deepl.com/pro-api
• Use the appearance settings to match your viewing preference
