Descriptions
Learn a language from YouTube with AI.
Language learning app that turns YouTube into practice: bilingual subtitles, shadowing, spaced repetition.
PlayLingo turns any YouTube video into language practice. Subtitles split by sentence, translation in context, and Lingo explains any word with a tap. Five ways to watch the same video: follow along, hide the translation, listen without text, rebuild the line, or say it out loud. Saved words come back with the scene where you heard them.
You know the words, but real speech still gets away from you: fast, blurred, half the sounds gone. PlayLingo turns any YouTube video into practice. Subtitles are split by sentence and synced with the video, every line has a translation in context, and Lingo, the in-app assistant, explains a word or an idiom in this exact sentence. The same video can be watched five ways: with subtitles, with the translation hidden, by ear only, by rebuilding the line from its words, or by saying it out loud while words light up as you speak. Words you save go into review on FSRS-6, the spaced-repetition algorithm used by Anki, and every card keeps the scene and the sentence. 67 languages, curated catalogs by level from A1 to C2, iPhone, iPad and Android.
