LingTube
LingTube is a Chrome browser extension that adds real-time subtitle translation, AI dubbing, and study tools directly into the YouTube video player. It supports over 100 languages for translation and can generate bilingual subtitles, allowing viewers to see both the original and translated text simultaneously. The extension also provides AI-powered text-to-speech voices that read the translated subtitles aloud, enabling users to listen to foreign-language videos in their preferred language without needing to read subtitles constantly. Beyond basic translation, LingTube can rescue videos that lack any captions by first transcribing the audio using speech recognition, then translating and voicing the result. It includes an AI summary and chat feature that lets users ask questions about the video content, get key point summaries, and jump to specific timestamps. An integrated AI study mode turns any subtitle line into vocabulary drills, grammar notes, and review prompts, making it a tool for language learners. The extension works on YouTube and also supports several other video platforms including Coursera, Udemy, Bilibili, and TikTok. Translations are cached, so replaying a previously translated video does not consume additional usage. LingTube is free to install with a pricing model that likely offers a certain amount of free usage, after which paid plans may apply.
