Translation, dubbing, and study tools stay one click away while the video keeps playing.
Chrome extension · YouTube
YouTube video translation, subtitle translation, and AI dubbing in one extension.
Open a YouTube video, click once, and LingTube turns foreign-language audio or subtitles (or videos with no captions at all) into translation you can understand. Natural AI voices read it aloud while you watch — so you no longer have to keep your eyes on the subtitle line.

Core features
Built for the way you actually watch YouTube.
Translation, bilingual subtitles, AI dubbing, AI summaries, and AI study — all integrated into one Chrome extension.
YouTube video translation
Translate subtitles, speech, and videos that ship without captions — all from the YouTube page you are already watching.
Bilingual subtitles
Show translation and original on screen together, or switch to just one side when you want a cleaner view.
AI dubbing and read-aloud
Use Edge TTS quality voices or the browser-native voice to read the translation aloud while the video keeps moving.
Rescue videos without subtitles
If a video has no captions, LingTube turns speech into text first, then translates and reads it for you.
AI video summary and chat
Once the translated transcript is ready, chat with the video to summarize key points, explain jargon, and jump to the right timestamp.
AI study from the exact line
Turn the current subtitle into vocabulary, grammar notes, short drills, scoring, and review prompts.

AI study
Turn any subtitle into a complete AI study session.
Pause on a line and LingTube builds a study pack right beside the video — vocabulary, grammar, drills, and spaced-repetition review.
Fits real watching habits.
Use LingTube during commuting, shadowing practice, or deep-dive learning on a single tough sentence.
Learn while your hands are busy
Queue AI-dubbed voices for podcasts, interviews, and long videos when you want to listen more than stare at the screen.
Repeat-after-me partner
Read the original, glance at the translation, then mimic the dubbed voice for speaking practice.
Slow down on dense material
Pause on one tricky sentence and turn it into vocabulary, grammar, and review content before moving on.
Private by default.
LingTube keeps its footprint tight and predictable — which matters when it runs next to the videos you watch every day.
Runs only on YouTube pages.
Settings stay in your local browser.
