## Description

LinguaLens turns everyday reading into vocabulary practice. On supported webpages and in supported YouTube subtitles, eligible occurrences of words you have studied can appear in your target language when the matching, context, and grammar pipeline can establish a safe result. Hover review controls and FSRS scheduling turn those encounters into retrieval practice. Import from Anki or Skritter, choose a starter deck, or build your own. Privacy-first: when contextual resolution is needed, LinguaLens sends only a bounded, short visible-text clause around the studied word—never full pages, URLs, or browsing history.
