Polygloat is a language learning app built on comprehensible input. Instead of flashcards or grammar drills, you watch a feed of short videos in the language you're learning. Tap any word in the subtitles to see what it means, and the app remembers it. It's free on Google Play, with Dutch, Spanish, and Mandarin Chinese available today.
Comprehensible input is language you can mostly understand — material where you already know most of the words and can work the rest out from context. The idea, associated with linguist Stephen Krashen, is that you acquire a language by understanding messages in it rather than by studying rules about it. Polygloat puts that into practice by scoring every video against the words you personally know, and showing you the ones that sit just past your current level.
Flashcard apps ask you to review words out of context, on a schedule. Polygloat spaces the repetition too, but the review is a new video: a word you're due to see again turns up in a different sentence, from a different speaker, days later. You never work through a deck — you keep watching, and the feed handles the timing.
Dutch, Spanish, and Mandarin Chinese. The app itself — menus, word meanings, and sentence translations — is available in English, Spanish, Dutch, and Chinese in both Simplified and Traditional script. More languages to learn are on the way.
It tracks every word you meet: the ones you looked up, the ones you watched past without stopping, and how often each has come back. That builds a word-by-word picture of your vocabulary, and every video in the library is scored against it. The feed then favours videos where you already know most of the words — which is the condition that makes input comprehensible.
Polygloat is free to download and use on Google Play.
