As answered by people managing Linglass and LayerStack Arm-based Cloud Server.
Linglass's answer
Self-directed learners who study through immersion — watching YouTube, Netflix, anime, dramas, and interviews in a foreign language instead of taking structured courses. They're typically intermediate learners who like the "comprehensible input" approach, often studying English, Spanish, Chinese, Japanese, or Korean, and want to turn the content they already watch into study material and remember new words long-term.
Linglass's answer
Linglass started from a simple frustration: watching foreign-language video is one of the best ways to learn, but the workflow is clunky — pausing constantly, copying words into a dictionary, then into a separate flashcard app. Linglass brings all of that into the video itself: dual subtitles, one-click translation and pronunciation, and automatic flashcards. It grew from a browser extension for YouTube and Netflix into a cross-platform tool that works on seven video services, with a web app and mobile apps for iOS and Android.
Linglass's answer
It works on the videos people already watch, on seven streaming services and YouTube, not a small licensed catalog. The free tier is genuinely usable (unlimited saved words and a daily translation allowance), not a locked trial. And it combines in one place dual subtitles, click-to-translate, native pronunciation with IPA/Pinyin/Romaji, AI grammar explanations, FSRS flashcards and AI subtitles for videos without captions. It is available as a browser extension for Chrome and other Chromium browsers, as a web app, and as mobile apps for iPhone, iPad and Android.
Linglass's answer
Linglass turns the videos you already watch into a language lesson without leaving the player: YouTube, Netflix, Disney+, HBO Max, Crunchyroll, iQIYI and Viki. It shows two subtitles at once, the original and a translation, and lets you click any word for an in-context translation with native pronunciation. If a YouTube video has no subtitles at all, Linglass can generate them with speech recognition and translate them. Every word you save becomes a spaced-repetition flashcard with a screenshot and audio clip from the moment you saw it, and saved words are highlighted when they come up again in subtitles.
