Loved by language learners

Real reviews from LingTube users on the Chrome Web Store.

An outstanding app that has helped my language learning enormously. Just tap a word to see its meaning — even words with multiple meanings are translated accurately based on context. It also has grammar analysis, and of all the similar tools I've used so far, I find this one's translations the most accurate. On top of that, it adds live comments (danmaku) to YouTube and Netflix and comes with AI features like note sharing, summaries and outline generation. Very practical. From now on, watching YouTube or Netflix feels so much more convenient and enjoyable.

This bilingual subtitle app is extremely useful for practicing my listening and speaking. It supports tap-to-translate and part-of-speech tagging, and the shadowing feature helps me practice speaking and compare differences in pronunciation. There are also AI summaries and outlines — very practical.

MageCode

I have to say, this is the best plugin of its kind I've ever used! It offers native AI support, which has greatly improved my learning efficiency. Both the interactivity and accuracy are top-notch—it's clear the development team has put in a lot of effort. I really appreciate you all. I wish you every success!

Dylan

Really, really great. My favorite feature is sentence merging: it joins fragmented captions into smooth, complete sentences and breaks them exactly where it should — perfect for learning English. It fixed my old pain of watching vlogs where people talk super fast in super long sentences and I had to keep pausing bit by bit... I'll keep supporting this app. It's seriously so good.

Jia Li

I'm usually busy with work and don't have time to watch full news videos, so I use LingTube to quickly generate summaries and outlines. When I need to note something down, LingTube lets me capture ideas in Markdown and later takes me back to the exact moment in the video. When YouTube's captions are poor, its transcription feature delivers high-quality reprocessing, and the quota is plenty for my daily use. Highly recommended.

仇学龙

After the improvements, real-time Korean translation is remarkably accurate. It brings together every feature you need for language learning and is really convenient — no more saving videos to analyze them separately. Shadowing and grammar analysis all happen in one extension. Super handy.

这是 YouTube 返回的 429(请求过多)限制:短时间内同一出口 IP 请求字幕太多次,就会被暂时拦截。最常见的原因是 VPN / 代理节点不够干净(很多用户共用同一 IP),并不一定是装了其他插件。遇到时请切换到纯净网络、清除浏览器缓存和 Cookie;如果同时开着其他字幕/翻译类插件,也请先关掉,等待一段时间后再试。
