LingTube — The next-gen AI video learning assistant Stop watching videos passively. Start learning from them. LingTube turns YouTube and Netflix into an immersive, AI-powered space to explore the world, learn languages, and capture knowledge — without ever leaving the video. Follow a lecture, a documentary, a show, or a language lesson: LingTube helps you understand every detail, grasp the big picture, pin a note to the exact second that matters, and share what you learned with others. ✨ Key features 📝 Bilingual subtitles Target-language and native-language subtitles side by side. Read, compare, and understand instantly — no more pausing to guess. 🧩 Smart sentence stitching Auto-generated captions are often split into broken, meaningless fragments. LingTube intelligently stitches them back into complete, natural sentences so the real structure is easy to see. 🏷️ Parts-of-speech highlighting Every word is color-coded by its grammatical role (noun, verb, adjective, and more), making sentence structure intuitive in English, French, German, Spanish, Japanese, and Korean. 🖍️ Select to translate (any length) This is more than a dictionary lookup. Highlight a word, a phrase, a full sentence, or multiple lines and get an accurate translation in a compact popup. Tap once to save what you didn’t understand to your personal vocabulary — no length limit. 🎧 Real-time interpreting Follow the video in your language as it plays. LingTube speaks a natural native-language voiceover of the subtitles in sync with the picture, so lectures, news, and films stay understandable without pausing. 🔍 Grammar analysis Stuck on a tricky sentence? Let AI break it down line by line — explaining the structure and why it works, like a private tutor for every line. 🗣️ Text-to-speech (TTS) Listen to natural AI pronunciation of any subtitle line. Multiple languages and voices supported. 🎙️ Video transcription No captions? Inaccurate ones? Awkward translations? LingTube uses advanced speech recognition to generate clear, natural, native-sounding subtitles from the original audio — so you can learn from any video with captions you can actually trust. (Available on YouTube.) 🧠 Summary & outline Get the big picture in seconds. LingTube generates a concise AI summary and a visual mind-map outline for any video, so you know the key points before — or after — you dive in. 🤖 AI assistant Ask anything about the video. Your built-in AI assistant answers in the sidebar: questions, context, cultural background, and deeper understanding. 🗣️ Shadow reading Improve pronunciation and fluency by repeating after native speakers, line by line. Record your voice, compare your waveform with the original, and hear your progress. 📚 AI vocabulary & phrase analysis Go beyond simple translation. LingTube gives you AI-powered analysis of words and phrases — meaning, usage, nuance, and example sentences — so you truly understand, instead of just memorizing. 📌 Timestamp notes Pin a thought to any second of the video. Write in Markdown, keep it private, or publish it. Public notes appear on the progress bar: tap an avatar to jump to that moment and read what someone noticed. Share knowledge, not just reactions — and turn every video into a notebook the whole community can learn from. 🎉 Danmaku (flying comments) Learning together works better. Share notes and reactions that fly across the screen, discover other learners’ insights, and turn solo watching into a lively shared experience. 🌍 Supports English, Japanese, Korean, French, German, Spanish, and Chinese 🎬 Works on YouTube (full features) and Netflix.
