Hi everyone! I'm the maker of LingTube. I built it because watching foreign-language YouTube videos was frustrating — I kept pausing to read subtitles. LingTube translates subtitles and speech, then dubs the translation in a natural voice, plus bilingual captions, transcription, AI video summary and language-learning tools. Works on YouTube, Coursera, Udemy, Bilibili.tv and TikTok. Try it free — happy to answer any questions!
