Langora — English Vocabulary Learning

Highlight vocabulary on YouTube and any web page, study it with spaced repetition, and grow your personal library. Works offline.

Langora helps you learn English vocabulary from the content you already watch and read — on YouTube and across the web. Highlight unfamiliar words, save them in one click, and review them with spaced repetition until they stick. HOW IT WORKS 1. Watch a YouTube video — useful words are highlighted right in the subtitles. 2. Click a word to see its Arabic translation and English definition, then save it instantly. 3. On any other page, click "Highlight this page" to scan it, then save words the same way. 4. Study your saved words with flashcards that resurface each word right before you forget it. FEATURES • YouTube subtitle highlighting — build vocabulary from videos you enjoy • Page highlighting — save words from articles, blogs, and stories on any site • English–Arabic dictionary — translation and definition in one click • Spaced repetition study — daily new-word limits keep sessions short and effective • My Library — search, filter, and organize every word you save (New, Learning, Mastered) • Explore Dictionary — a built-in dictionary with 24,000+ English words and phrases • Import & export — back up your vocabulary or move it between devices as JSON • English & Arabic interface — fully translated, with right-to-left support PRIVATE BY DESIGN Everything stays on your device.
